Hi Dino. I found your channel today while installing my (used) 5.3 gal Acerbis tank and I didn't have an installation guide. Yours was the only video detailed enough to show the hardware and answered my questions. I can't say enough good things about your videos. The quality, care, preparation, and effort you put into them is amazing and your positive attitude makes them even better. I feel like I'm watching a fully produced show on cable. You got an instant subscriber here 👍 Please keep it up and I'll continue watching and learning from you
Thank you for the comment and I'm glad you are enjoying the content
Dino
No one is as professional on youtube as you. Thank you!
Your welcome, glad you enjoy the videos.
Dino
@@DinosTinkerShed I do! I don't know if you could help but.
Unfortunatly it look like I can't tune my bike correctly even with your videos :(
The first 1/8_1/4 of throttle is boging. All stock except Main jet is 142. A 2021 with 40 000k. I have a Factory Pro jet kit from Procycle. I tried the new needle with many clip position didnt work so I put the stock one back. I have a another pilot jet screw in my kit should I install it?
Hi Dino, just wanted to thank you for your detailed and meticulous videos - they are really amazing..! I am a DR owner (albeit the 800 BIG variety) and I changed my clutch last weekend by following your step-by-step guide. It worked a treat - THANK YOU!
So glad it was helpful. The first DR I ever rode was a friend of mine who bought a brand new DR750 in the late 80's. Awesome ride.
Dino
This video is very detailed - voice and picture - regarding the DR 650 carburettor. It has all (and some more) of the information needed for servicing the carburettor (which has some delicate parts being a diaphragm carby). This video does not skip over the important aspects of gently handling the disassembly or the need to be careful with compressed air - both pressure and direction. Anyone who does DR maintenance will find this useful. Thankyou Dino.
Thank you Mal, glad you liked it. I hope you enjoy the next part on the jet kit installation as well
Dino
Thanks Dino, I can’t tell you how useful this video is. After 19 years of ownership I have finally decided to try servicing my non functioning carb on my 2002 DR650 SE. Cheers from Bristol UK.
That is great, glad I was able to help. Good luck with the servicing, just take your time and you will be OK.
Dino
You're the only channel to my knowledge that actually makes everything CLEAR and give a CLEAR view of everything and easy to understand!
Wow, thank you for the feedback. I'm trying.
Dino
@@DinosTinkerShed No, you're more than trying. It works. I've been into bikes my whole life but working on them has been a struggle for me due to just only loving riding and not fixing them and not having enough space or tools but with this video, I feel confident enough to try and work on it.
Wow, I am very happy that my videos help you out. Thank you again for taking the time to comment. It is really appreciated. 😁
Dino
Hello Dino your carb video helped me get mine cleaned and my DR up and running and I just viewed your clutch adjustment before ride that wax about to be cancelled because of issues. Your channel is very easy to follow and a life and money saver for me and a lot of other really fees I expect - thank you
I'm glad that you enjoyed the videos and find them helpful, thank you for the comment.
Dino
Hey, thanks for the in-depth on how to remove the carb. A lot of the forums just say “it’s the easiest thing!” But I’ve barely ever worked on a bike and barely understand what a carb even does….your help much appreciated.
So glad you find it helpful, I know myself the first time I popped open a carb it was intimidating. An actual mechanic once told me that if you take your time, take pictures as you go and do a bit of research before you start, most anyone can repair things. The key is taking the time to try, good on you for taking the steps.
Dino
Wow, this was an excellent video! Thank you for the thorough explanation of all the steps, they’re really helpful.
I see I will need JSI screw drivers, and welding tip cleaners. I' me learning alot from your highly instructive video classes. Thankyou.
I am really glad you are finding the content useful. If you are going to buy just one driver, and not the set, the #2 is the most often used driver I have.
Tha ks for the comment
Dino
man, i love your patience and dedication to do this tutorial, thanks from chile, southamerica
Thank you for the kind words, so glad you like the content.
Dino
Thanks , Dino. Love your channel !
What a fantastic video. So thorough and in-depth. DR650 owner’s are very lucky to have your expertise. Thank you so much and please keep up the good work.
Thank you for the feed back, I'm glad you enjoyed it.
Dino
Great video, my new favorite DR tutorial Channel. Keep them coming Dino.
Thanks man, nice clear video for a beginner like myself 👍🏼
Ha, ha! that's what I did yesterday. I pulled out my BST40 outta my 640 Adventure, cleaned it, out back together and mounted back on the bike. That was really satisfying. I ran out of time yesterday so today is a startup day... Hopefuly everything works. BTW i watched your video after the job but still had tomake sure I put everything back together correctly
Sounds like you had a fun project.
Thank you for the comment.
Dino
I just wanted to say thank you for the videos. I’m a novice at best and these are very helpful. Nice job and glad I found your page.
Awesome, thank you! Glad you enjoy it.
Dino
VESSEL - makes some GREAT JIS screwdrivers and other tools. The Suzuki DR650 is such an AWESOME BIKE and way underrated by those who say it is 'outdated'.
Thanks for the tip on the vessel tools I'll check them out. Sometimes I think we " outdate" things ourselves and forget about the benefits of simplicity, is the DR perfect, no but neither is any other bike.
Thanks again for the comments.
Dino
@@DinosTinkerShed Agree - the DR the small mods make huge differences. You will like the Jet kit it is AWESOME!
They do an awesome impact screwdriver. A little pricy but it's well worth it, I just bought one to disassemble my CCM 644 engine (which is a twin carb version of the DR650 from the xf650). I'll never go back to trying to make do with a Phillips head.
@@elobiretv Agree, the Vessel are like kinda a hidden gem. If only I knew about them like long time ago.
Wow.. the Milwaukee trick was just perfect. I was able to put a lot of force on those bolts without damaging anything. Your videos are great and easy to understand! Thanks Dino!
Thank you, I'm glad you enjoy the videos. Thank you for the comment.
Dino
Thanks Dino, you must be a teacher. Great vid
Thank you for the complement, I hold teachers in high regard but I am arborist by trade, I just like to talk lol.
Thank you again for the comment.
Dino
This is one of the best videos I've watched. Very in depth. Thanks.
So glad you enjoyed it,

Fantastic video, Dino!
Very concise, and paced perfectly!
I’m off to watch part 2!
Awesome, thank you! enjoy part two.
Dino
@@DinosTinkerShed when?
@@slavkomesiah3615 When will the next part be out? I already released that one and am working on the tuning video now.
Dino
Hey Dino! Thanks for the vids. I definitely would not have taken on the carb clean and pro cycle jet kit without your videos. I sincerely appreciate it. If you ever find yourself in western Colorado, give me a holler!!!
Wow, glad the videos helped you out. And thank you for the offer I would like to visit Colorado sometime.
Thanks again
Dino
Bloody great vid mate. From Australia
Thank you so much, glad you enjoyed it
Dino
I got a 2006 DR650 with 1,200 original miles it had been sitting (put on a Clarke gas tank as the original was rusted) from siting. I got a Mikuni made 'kit' from Procycle worked perfect. Been riding for years - Carbs are easy to work with and easy to tune. The JD Jet kit wakes up the DR650 first thing I did as well. I put on Twin-Air as well, and got rid of the vacuum petcock. Put on a manual (Raptor Yamaha one). --- EXCELLENT VIDEOS!!!!!
Thanks for the comment. Even in tuned the throttle response in the shed is noticable to be. Can't wait to tune it and try it out.
Dino
@@DinosTinkerShed It is a 'night/day' difference. I have put about 500 miles on it and I put on new tires/tubes as well. Did the 520 - oring conversion kit to. I am going to put on the GSXR exhaust - Procycle offers the pipe to connect. Then hopefully do front suspension Fork Cartridge Emulators. I got a RM250 I am rebuilding right now as well.
Great vid! Very informative and well presented. I’ll be reviewing this again, and I’m looking forward to the next installment. Thanks Dino!
Glad you enjoyed it
Dino
Thank you Dino, amazing job with the video and description!
Well done nice presentation Similar carb on my Suzuki ATV helped greatly.
Thanks Brother from Utah. My 2017 Dr has seen the Rockies and Moab more times than I can remember. Would not start this spring. I did the usual Sea Foam treatment, etc. Pulled the carb today and was surprised from all the fine red dirt from Moab and utah. Used a carb cleaning fluid and reassembled. The slide was filthy, which surprised me. Anyway, adjusted the valves and cleaned all the gunk from the spark plugs from the resulting in many...many attempts to start prior to cleaning. I put it all back together just two hours ago. Installed a new fuel filter. And..Wow..I just touch the starter and she runs good. I did adjust the mixture and idle of course. I'm 57 and this bike will give me many more years in the Mountains and Desserts of Utah. God Bless...
Hi Dino, thank you for your videos. If I am on your CZcams channel it is because my bike does not start (not cool) but with your guidance, I feel confident enough to clean this out myself with a friend. Thank you this is perfect for someone with bike issues and without a dad into bikes or mechanics.
You'll do fine, make sure to check for spark as well, a friend always helps, they can sometimes see things you may not. Good luck
Dino
I buy a used bushpig about 2 months ago. Pass test for full endorsement 4 days ago. Yay me......
Anyway, I cant find any videos covering adjustments without taking things apart.
Video suggestion: adjustments to stock bike without taking anything apart.
I buy my 2005 bushpiggy with mods: frs exhaust. Kn filter. Finger idle screw. Pro Taper handle bar. Acerbi 4+ tank. Acerbi bark buster. Acerbi bash guard. I just bought it, I love it and I dont want to take it apart! I buy from unknown previous owner. Engine and gearing are stock im told. Only cosmetic mod or upgrade cause you broke something.
Thank you for the comment and suggestion. many of the adjustments do require some disassembly. Would you be thinking of things like clutch cable adjustment, oil changes, air filter cleaning ect?
Please let me know.
Thank you again
Dino
Thank you for making this video Dino! This was my first time cleaning/rebuilding a carb and it was an immense help.
Great info! Very detailed.
Great information! Your channel is awesome. The information in your videos has inspired my wife to learn how to work on her own bike. Keep up the good work! Cheers
That's great, I am glad that you and your wife enjoy the content, it's a fun hobby for sure and for me anyway part of the fun is learning about the bikes I have ridden.

Top notch videos
Thank you, glad you enjoy them
Dino
Thanks for great detailed video,
Fun fact difference between JIS and Philips screwdriver is the tip of the screwdriver.
JIS = flat tip
Philips = pointed tip
Use JIS on any Philip head screw but not Philips on any screw.
Simple solution take a Philips head screwdriver and flat-out the sharp bottom out. Thus now u have JIS.
Very cool, the ps3.
Thanks not sure where ps3 Came from, auto correct I guess.

I see the pilot jet at 24:55 . Thanks again Dino ! 👍
LOL I was going to recommend checking out the the cleaning video but you found it, fantastic. please keep me posted on how you make out.

Dino can you list the part numbers for the float gauge and ultrasonic cleaner please or are they listed somewhere
Excellent Video clear and precise, The details we're extremely clear some of the best camera work I have seen on CZcams, well done just as a matter of interest what make and model of Camera did you use ? 👏 👍
Thank you for the comment, I am glad you like the video and camera work. For most of my shots I use a Sony ax53 video camera. I do have a video on all the equipment I use and you can find it on my CZcams page.
Thanks again for the question
Dino
Thanks for the reply be safe 👍
You deserve way more subscribers!
It helps if you secure the carb in a vise with protective jaws which allows very accurate pressure on the screws, also never use torch cleaning tips, they have serrations that will damage the orifices of the jets, just use smooth wire, while your at it replace any rubber O rings and seals with one's that can resist ethanol fuel, a guy named Gregory Bender at thisoldtractor sells the kits.
Good tips, thank you. I will say that every small engine mechanic I know uses tip cleaners to clan carbs, I am not saying they are right but they have never indicated that they have issues with the proccess.
Thank you again for the comments.
Dino
@@DinosTinkerShed Thanks Dino, I can't tell you how many mechanics I've known who's heart wasn't in it, they don't know any better.
Hi Dino, Today i noticed that if you fasten the front screws on the Safari-tank first and then the 2 at the seat it goes on much easier. You wont need as much force.
Interesting, Ill have to try that next time I have the tank off. Thank you for taking the time to pass this information on.👍
Dino
Hello,
Thanks for your video.
Have you ever had, at constant speed (90km/hr), like a slight lack of gas or a slight variation in speed? My chain tension is good. I doubt my carburetor.
Thank you, Alain
Hi Dino. Thanks for sharing. I might purchase the same carb for my DR 600 S (85) and your video helps me. But where do the thickest hose near the brake reservoir ends and what is it for? I believe the thinnest hose is for fuel ? My old Mikuni doesnt have that port. My writing might be a little norwegian english :-) Roy
Thank you for the question Roy and I love your Norwegian English. I will double check this but I am sure the fat line runs under the seat to a small air filter. This allows the bellow in the carb to operate properly when vacuum is generated by the flow of air through the carb and allow the slide to be pulled up. Again I'll check again tomorrow just to be sure.
Dino
I need to check my carb.
Greetings Dino,
As always another excellent detailed video.
I have a technical question for you.
I have a 2023 DR 650, do you think if I remove the charcoal canister and the PAIR valve systems will affect the carburetor functionality/performance?
Thank you for assisting me, keep producing more videos.🇺🇸☕🎉🇺🇸
Thank you for the question, unfortunately I don't have an answer for you as I've never removed a charcoal canister. I always recommend posting a question like this on drrider.com, there is most likely a few people who have and would love to help out.
Thanks for the question and I wish I could be more helpful
Dino
Just be thankful you don't have an early bmw f650. Why oh why did bmw think you needed TWO mikunis for a single 650 . I spent an hour last weekend pulling apart my DR wouldn't start. Pulled ot apart and gave it a quick clean and all was good. Went to start it a few days later. Same thing. Ended up doing first what I should have done the first time. Tapped the fuel bowl and it then started fine. So I have a sticky float which I'll get around to fixing at some point.
Two Carbs? wow, they must have thought twice the fun to clean and set up, LOL. Seams a bit overengineered but they do make great bikes for sure. As you point out the DR is a bit more simple to work on. Thank you for the comment.
Dino
Hi Volvog, did you get your float unstuck? Was that the problem?
Thanks,
Ken
@@kenholland683 I did. The needle looked perfect so I ended up putting some cutting compound on a cotton wool bud (q tip I think they call them in the U.S.) and put that in a drill and smoothed out the seat. It was fine for a week but as I had ordered a new needle and seat assembly anyway I had it swapped out by my mechanic whilst he was doing some other work to the bike. I don't think the needle is available as a separate item but as the bike is a 95 I don't mind replacing things as preventative maintenance.
@@volvogt21 Thanks, yes might as well replace while you're in there.
Cheers
Early bmw?
My carb is leaking gas, i think it's the float valve system, do I need to replace it or it can be adjusted? Nice videos I hope you are doing ok in your heavy machine operator courses.
Thank you for the question, again I'm not a mechanic but I will give my thoughts. The is serviceable and it may be best to first give the entire carb a good cleaning to ensure nothing is stuck in the float needle valve. Once clean check the condition of the float needle tip and take a look in the port that the needle sits, the seat at the bottom should be in place and in good condition. When putting it back togeather check the float height and adjust if required. If this does not stop the leaking you may need a new float, needle and seat.
Hope this helps.
Dino
Hey Dino I just picked up a 1991 Suzuki 650dr and it have been sitting for 5 years I’m not getting any spark i checks the kill switch’s but still can’t figure it out
Do you have a multi meter to check voltage at the coil?
Dino
Help Dino!
After cleaning the carb, installing an acerbis tank, and a procycle jet kit my dr hasn’t been able stay running. The tank doesn’t seem to want to flow fuel in the on position, but it does in reserve. With that said, I put maybe a gallon just to see if it was going to work. So is the tank not flowing cause there’s hardly any fuel?
If I run it in reserve, it dies after about a mile of driving and it seems to always die when I throttle down. To start it back up I have to open the throttle completely. Any ideas?
You are correct, the red is ment to draw from a lower level than the on position. Its a bit of a safety so you don't run out of gas. You will need to add more fuel to the tank to get the level high enough for the on position to draw fuel
Dino
Did you get the choke seated correctly after the cleaning and jet kit?
Also, remember that the fuel you put in is split on each side of the tank so a gallon may not be enough to keep it running to long.
Hi. Dino what the make of your ultrasonic cleaner
I believe it is a CREWORKS 6 liter. I am sure it is sold under different names but all are made in the same factory.
Thank you for the question.
Dino
what do u use to clean the membrane?
Just water. It's cheep enough to replace as well. I did find I did not need it for the jet kit though, just finishing the tuning today..
Dino
My dr650 doesn't idle by itself. It starts badly and is misfiring a lot. Is the carb the problem? It sat in a barn a long time.
Although it is hard to tell for sure I would say you are the right track here. Most likely the carb is gummed up.
Thank you again for the question.
Dino
@@DinosTinkerShed Update: I cleaned the Pilot Jet today and the bike runs perfectly now!
@@kekerlek7761 right on, that's great to hear.
I see you blanked off the vacuum to the pet lock. My question is I guess you now have a normal petlock without the “prime function” are there any benefits to this
What size JIS driver are you using, +2 or +3?
Number 2
@@DinosTinkerShedThank you sir :-)
I see so many people drilling air boxes, adding slip ons, and getting new carbs. Am I wrong for being totally fine with the stock setup?! 🧐
Nope, stock is just fine. Mine is pretty much stock other than an adjustable fuel screw to help with cold starts and a bit richer main jet. I do like to experiment but I try not to do anything I can't reverse. My goal is smoother running not really more power.
Dino
Unrelated; have you modified your suspension?
I did not but a previous owner did add a heavier rear spring. I have not had the forks open yet but I do not believe they have been modified.
Thanks for the question
Dino
@@DinosTinkerShed the only reason i ask is because I just finished doing a 9.6kg racetech spring in the rear with 10w oil, and the .8kg fork springs, also with 10w oil, and I am thoroughly blown away by how much more confident it feels on and off road. If I had it to do over again, I'd probably do that first. I'm a 240lb guy and it actually feels tailored to me now.
16:50 video starts
great video but probably the most ads I have seen in a 30min clip
I know adds are a pain, it is how I can make a bit of cash for each video and I appreciate your patience with them. Even if I turn off the monetization, CZcams will put adds on lol, I had ads on my channel even before I qualified to monetize. Again, sorry for the inconvenience and thank you for your patience.
Dino
They say hazardous waste depot, we call it a ditch.
can someone please help me ID the hose at 6:30. The big hos, I believe goes to the breather filter up above the air box, trying to remember if the smaller/bottom hose is just a vent or where it routes to. Thank you
Hey thank you for the question. I belive the smaller hose is the vacuum port for your petcock .
Dino
Hello! Thanks for this very helpful video! I realized while taking off the carb that my vacuum port had nothing going to it. It looks like an aftermarket petcock that doesn’t have a vacuum port. I’m assuming I should block off this vacuum port instead of leaving it open correct?
@@mitchellkauffman6799 yes you should. You can get caps on Amazon in a kit
@@DinosTinkerShed awesome, thank you! So did both this port and the vacuum line that you pointed out on yours both go to the petcock?
If the small port is not capped off can this cause issues?? If so what kind of issues? Thanks !
I thought you would have removed the throttle valve guide out to inspect for wear ...
I did consider it however it looked relatively new just looking from the outside. This is not accurate by any means I know but I thought it could be done in more of an overhaul video in the future than in this one which was more focused on cleaning.
Thank you for the comment for sure.
Dino
@@DinosTinkerShed While it is common practice to inspect & replace worn parts etc while stripped to that level I do understand your position for creating these videos under specific titles ... here in Aus the guide is not available under the OEM - E24 DR parts list which deletes the carb as being sustainable by replacing worn parts ... this is a presumed deliberate move to force the purchase of a new carb when the guide is designed to wear & be replaced ... which would be described as a consumable ... as you have shown is available to purchase in the US ... cheers mate ... you do a great job on these vids ...
