- Hold on to your shorts EveRide, this may freak you out when you see this episode. Don't worry, everything can be reversed if you don't like it. We get a surprise visit from the Brother in Law "Dirty Sanchez", who provides supervision and entertainment (edited out, sorry.....). We find another problem that needs addressing, and our best intentions have to be reversed because of an unforeseen road block. We're making progress, but going crazy waiting for the bling factor to start!!!
I think you helped me out so mich man o been looking for this video for years. Barely nobody has this fing carb
Great Video - Just bought a super clean 03 KLX400, but it ran terrible - wouldn't idle - I had trouble finding information on the "Coast Enriching" circuit - and that was my main issue - Did pretty much everything you did hear, and my bike is running 100% better - Thanks.
I have too many things to say on this one... first of all, 5% increase in HP?! Yes please! When you removed that big chunk of the Carb I only pooped my pants a little... I figure you know exactly what's going on so I have some pretty sturdy trust in you. I'm sorry there are all these problems popping up. I'm glad its in good hands!
Did mine today and the deceleration circuit is gone , thank you for the vid solved my problems
14:00 talking about the fuel screw - I managed to get that same aftermarket screw in the carb. It's almost touching the starter but it fits.
You can do it!!! I wouldn't waste the money on a spare bike if it were me, I would just read the manual well, read what you can on the internet, and take you time. If your not sure what to do, ask around, and you'll find that it's not near as bad as you thought it would be. You'd do great!
It does sound like needle adjustment to me too. Without being able to see, hear, and or feel what is going on (it's hard to interpret a description of sputtering) it's hard to say what direction to go. Start by dropping the needle 2 clip positions, and see if it gets better or worse. If the "sputtering" is worse, then go the other direction by raising it the 2 notches you went down, and then plus one, then re-assess it.
For the idle mixture adjustment, I used one of those flexible ones on my E. works like a champ..
thank you very much for taking the time to teach us how some of this stuff works
Many air boxes are Tuned. I had a 1986 Moto Morini 501 Camel. V twin. I removed the tuned cones and reverse cones in the air box and the bike wouldn't run. I had to increase the main jet by 2-3 and raise the needle. A little more HP and still got 50mpg+/-
It's been suggested that soaking a KLR 650 carb in Pine Sol overnight (the metal parts only) after disassembly is an environmentally friendly but still effective way to clean it. Ever heard of that one please? You guys are great for doing this for eveRide!!! I hope to have friends like the two of you one day. Thanks!
I haven't heard of that, I've always had good luck just using carb cleaner spray, so I guess I've just never had a good reason to change.... I dont use a lot, only just what I need to get things clean.
Gday I’m about to install an FCR39 on my 2017SM. I got the carb from a 2017 E. I have rebuilt the carb all except the mid body as I didn’t have the courage to seperate the gasket cement that adheres the mid body to the top of the carb. I’m ready to go. Your videos are good and I’ll be referencing them along the way.
I’m not experienced at this at all and tuning the carb will be the next adventure once I get it installed.
Great job man!!
Great job man! I think the next bike you should do is a KLR! Only because I have one and want to have a good understanding of how its set up. Thanks for sharing.
Nice! I hope you include all of us in on the adventure!
Nice video. I only wish you would have shown how to do the MID BODY removal and a new gasket install on the mid body. I understand that the mid body of the FCR Slant 39mm Keihin carb often gets overlooked and/or just plain neglected on carb rebuilds.
If I come across another one to do, Ill definitely pull it all the way down. The mid body disassembly and rebuild is a real PITA and has to be perfect or it will leak and drive one crazy trying to tune it. I do them all the time, but have been nervous to show ithers how to do it....
Thanks my man, I have to keep an extra roll of paper towels just for Rojo. You folks are great, thanks for the props :)
SOOO much innuendo! I'm surprised the camera lens didn't get all steamy. I'll chip in for the "eveRide's new uncrapped pants" fund, I assume that will get spearheaded after he sees this video.
That's a shame the adjuster couldn't be used, those can be very handy. Awesome stuff senors.

Hey so my bike has the stock Jets in right now but is has their thing where it high idles. If you put it in gear and let out the clutch to give it a bit of load it revs down but the revs back up again. I'm thinking somthing is clogging the carb.
Also I was wondering can you remove that low fueling thing that is attached to the carb without modifying the Stock jets?
Thanks
I was meaning about the deceleration in richening circuit
Well, it's a dynajet kit, and you select the proper jet for your altitude, pipe, and any other mods based on the description in the dynajet instructions. There isn't really a "Stage" as some people call it.
Excellent video and info! Getting ready to do this on mine and this will help a lot!
I'm dyne here! I'm so close to finishing a frame off rebuild on my
2001 DRZ400k1 ( kick start ) original owner. Maybe 1000 total miles. She has the FCR 39 flat slide. She's always been tuff to start. The process go's like this pull on the compression release lever. Kick it over three times then let the lever go and kick it HARD
WITH GAS! What's the best plan of attack for this carb. Best setup for Vegas sea level. Thanks for all you do.
Where did you get the jets kit ? Or part number ?
Been a long time ago my friend..... I cant remember....... If I have access to a dyno, I just tune with stock components. Nowdays we build 470 motors and use 39mm FCR carbs, which I have jetting specs for if you decide to do that someday......
Went from a 158 main and 45 pilot, to a 165 main and 48 pilot. Have open box and full Yoshi off road exhaust. Way to rich. Around 200 400 above sea level and sometimes higher. Another guy with one had the same problem. Had to go back down in size. A lot of confusing info on the kicker only drz. Most suggest to go way to rich.
My man....We just like to play, this is all good stuff for people to check out, don't be sorry, this hopefully will help a lot of folk.....You better get your depends ready, because Rojo and I can't wait any longer, we might post up something tonight that's gonna make you end up in the hospital......
picked up a 03 klx400r. Im doing a few mods and one is this dynojet kit. I assumed it came with a pilot jet but it didn't. I live in eagle mountain just around the corner from ya. Im wondering if the larger pilot jet increase was needed. or how it ran with your jetting.
Oh and I also removed and plugged the vacuum ports on the enrichment circuit.
+james wilson hey buddy! actually, we ran the stock pilot jet, and it has worked good. As we go up in elevation, carbs run more rich, so if anything, you would go down a size. I think you would be happy to leave the stock pilot jet in, especially if you go down south to ride where the elevation is lower, then use the recommended needle and main jet from the dyno jet kit. well done bud!!
+MrDuhfactor so the stock pilot was a #45 in the video you inatall a #48. did you go back to the stock later? thanks for the advise.
Should have done the "Taffy Mod" on the accelerator pump circuit linkage of that FCR carb or the "Eddie Mod" version as seen on Thumper Talk.....
I have a drz 250 and it bogs when openning the throttle fast how should i mod it?
We've got some killer stuff planned for the KLR, you won't believe it, trust me. It's never been done before.....That's if it works out the way we plan....
Make sure you post it on them major KLR forums, these people swarm over this kind of stuff like locust.
No problem my man!
Grind the aftermarket fuel screw down. Then clears the starter motor.
Also, is there a trick to removing/installing the carb on a drz 400e? Worst one I have ever removed!
Not sure what Mr. Duh is up to these days, I'm hoping he sees my fork damper rod tool/ lack of question....Removing the reg/rec helps a lot to remove the carb. Drop it down, then sideways.
Hi there. I tried closing all those 3 holes n remove the Circuit thingy. But then. My bike start n keeps on dying. Why is that so? Thanks
Do you remember the main jet # you put in? Stock looks like 140 or 142.5. One mod I saw used a #160 to rejet. I will be running around 6000'.
g w Sorry bud, we used a dynojet kit which uses different jetting numbers which dont coorelate with stock jet sizes. I would check some forums and see what others ended up with who used stock jets. Good luck!
so, what his the black knob showing on the carb at the beginning of the video if its not the fuel mixture screw? not sure what I'm looking at.
...idle adjustment screw
Hiya. My drz is sputtery right in the mid-range. I took it to the shop and they claimed it was just a dirty air filter. They cleaned it and said it was good to go. Then about a week later (only riding on the street) the same problem has come back again( I never thought that was issue.They said the carb wasn't dirty and did not need any adjustments, but something is def not right. The bike has been jetted, and the problem.Think I have to move the clip on the main needle? If so in what direction.
You are a inspiration to me. I think I am going to try to rebuild my KLR this winter. I'm in NJ so I will get 3 months to do it. Might buy a junk bike to practice on. Any suggestions?
You said it right my man....
Mr. D......what stage jetting is that? Im trying to do this to my drz. I have the same exhaust set up and stock motor. I
What state are you located in? I have a 01 400e that needs some work and for some reason the one thing I can’t wrap my head around is carbs
Im in Utah buddy....
@@MrDuhfactor ah man, im all the way in virginia lol, it feels like when i get to the top of rpm it climbs and then nothing just loses power. Everything is completely stock. Gonna give it a clean and see what happens but if you have any ideas let me know. It could just be me I’ve been riding and gotten used to supersports so the bike might be fine
Very informative, Thanks
Great work guys! I wish I had an FCR carb on my bike :D
Just saw this video as I need to address a carb issue with my 2004 DRZ-400E. I am running a pro-circuit muffler/exhaust, have done the 3X3 mod and have a dynojet kit installed. The problem is, I am now in Houston which has no elevation and the bike won't run unless I have the choke on (or, it does not run at all). When the dynojet kit was install (TRE in Simi Valley, CA) I was at a different elevation and used to ride in the high desert. I then moved to the Reno area and had no issues either. What is the right combination jetting wise to run here in Houston Texas?
Im not sure bud, I use a dyno with a sniffer to get the jetting right.... if it only runs with the choke on, then your too lean... you need to upsize your pilot and main jet, as well as raise your needle (drop the clip position 1-2 clips).
Hi, how do you adjust the position the control ignition (that one of the black cable), i disassemble mine and don't know the correct position or how to adjust it. Im having problem to start the bike! Thanks!
Sorry man.... That was long enough ago that I can't remember. I do know that it is described in the manual though. You need a volt meter to do it. I don't think that has anything to do with your bike not starting though, a lot of people just unplug it. Good luck!
where can i get those rubber jet passage plugs? and where can I get a replacement for the throttle position sensor?
Rubber plugs, any automotive store like Oreilies or autozone, TPS, any suzuki dealer. Good luck!
Nice Video.. Lots of good info. Thanks!
MDF, I have a 2005 DRZ 400S, unmoded. It sounds like doing the 3x3 mod without also doing a jet kit would be futile. I'm in Sacramento, so near the Sierra foothills and higher elevations. Wondering what jets to install given the wide range of elevations likely to be encountered. Thanks for your advice.
Well, doing the 3X3 mod without jetting still may yield some benefit, although small. If you open up the airbox, and exhaust, you'll want to work with jetting to maximize its fuel efficiency and power. Always jet for the lowest elevation you ride in, then it will richen as you climb in elevation for mountain riding, which is still safe. The DRZ can handle a large range in elevation and still run great. We've had EveRides bike from 3000ft up to 10K+ and only dropped the needle one notch from our starting point for it to run excellent in that wide of an elevation envelope.
MrDuhfactor Thanks for the prompt response! So, the stock jets appear to be set for some range of elevation, since the manufacturer doesn't know where a bike will be ridden once it leaves the factory. Also, I have a stock exhaust but would entertain modifying that while doing the 3x3 and jet kit. Any suggestions along the lines of muffler/header? I have enjoyed your videos as they are very informative and entertaining. Am a noobie to DS.
Mr Duhfactor congrats for your awesome job. I have a question, if I may... What mods would you do if you have to travel with a 2001 drz 400 to 12000ft. Thanks
from a carburetor stand point, I would say just take the appropriate Allen wrenches and screw driver to get your carb top off and change needle clip position. if your bike runs good at lower elevations, you might be surprised that it still runs decent that high up. if the needle is on the rich side, as you climb, the bike will start to sputter, be hard to start, and lose power. drop the needle one clip, and it will run like a champ. good luck!
I have to travel about 3000km before the climbing . I 'll go with two guys with 1200 adventure and I dont want to make him wait for me too long. I think I can do it in the hotel at night or if we stay a day in Salta- Chile( foot of the mountain). If I did the dynojet and 3x3 mod, I need to reajust the needle ? thanks, you are really helping
What is your opinion on rerouting or fitting T's to the carb vent pipes to avoid the engine cutting out when riding through deep water? Which pipes would you reroute?
Hmmm..... I don't have the bike here to look at it to give you some suggestion, are you talking deep water, like water above the airbox???
My DRZ400E dies when riding through water at bash plate depth. Some forums say that leaving all the vent pipes to hang down by the swingarm is the cause and that 2 pipes should be routed up from carb to stay at atmospheric pressure.
Anthony Phillips my man, we havent had trouble with that so far, I would ask on that forum for someone to give you some direction, truthfully, not having the bike here to look at, I'm not sure which ones to suggest. Sorry mate!
also what stage jet kit did you use?
Is need to go to a higher stage jet than 1 with that setup? Thanks
AH! *consider the pants pooped*
Would a stock exhaust and FMF header create an issue? I initially had full FMF exhaust on my DRZ400E 2009
Create an issue for what? Not sure I understand.......
@@MrDuhfactor wont start. Turn s over. Replaced plug. Clean petcock.
Do you have a tutorial on testing/adjusting throttle position sensor? Thanks for your time
I didnt on this bike bud, sorry. I think there are some other model vids out there though....
@@MrDuhfactor thx!
Thanks Homie, You're the best.
About 473......Especially w/ Rojo around..... :)
If you don't mind,what is the part number for the JET KIT?
+razvan6899 Crap dude.... so sorry.... this was so long ago I have no idea where or what it was.... It was a dynojet kit, maybe rocky mountain ATV has it?
Ok,thanks.
are the plugs needed pipe thread?
where did you get the throttle position sensor?
local dealer buddy.
I'm a bad camera man, but we'll do our best....
does the air box mod and different jetting make the bike consume more fuel?
+Dan Oliveira It hasn't actually consumed more fuel interestingly. It seems to get better fuel mileage, maybe because the fuel mixture is metered better, and more correct.
+MrDuhfactor awesome, this is good to know. thank you for all these videos, I learned a LOT
I got a new DRZ400e 2012 and mine dont have a snorkel its just an open hole, its almost like they forgot to put the cover on it. Is this meant to be like this or should I do something about it?
Wow, not sure on the 2012, maybe they did that intentionally since it's one of the first mods most people do to their DRZ's.
I was thinking the same thing, But because its a new bike its only got the factory exhaust so I dont see why it would be like that. Strange.
Oh and It would be great if you could make a video on installing a kick start on a DRZ, Ive only found one on youtube and its in a different language
Good idea, the bike is one of our friends, down in a different part of the state, so we might not get a chance. If he decides to do the kick start mod, I'll ask him if we can do it up here in the shop and do a video for you.
That would be great
Only a snorkel on the Yank version of the E.
How many rolls of paper towels do you use per bike? haha
where do you go for carb parts for the drz ? I just picked up one and figured out what the bog off idle was....no plunger arm for the accelerator pump and can't find anyone that sells one. spent hours on ADvrider and Thumper talk as well as every conceivable way to word or spell what i need on google without luck.
I usually look either at Rocky Mountain ATV (May not be on their website, best to call them) or call Tom at Duffs racing here in American Fork Utah. It may be looked up by "Duff Shelley kawasaki", Tom rides one and knows where to get all those kinds of parts. Good luck!
I would love to know 1/2 of what you do!
At what minute is the tube that must remain....
I guess I was thinking of another bike or something Tom, after re-watching it, I am reminded that it was just the three nipples that needed plugging....I think I confused the extra tube with the SAS removal process on a KTM 990.
Whew, thought I was on drugs....
I’m rebuilding a 2001 DRZ the guy I bought it off told me it was a 2006 along with cheap Chinese parts he put on it, I’ve already bought quite a few parts for a 2006 and need to know will it fit on my 2001 the bottom end i bought from a 2009 Sm is a huge concern it fits the 2006 but what fits the 2001, there’s no kickstart so I’m sure it an S model...please help me...And I mean rebuild from the frame up...everything...I would like to do business if you can assist me, I want after market carbi and a big bore kit by Athiena but I literally want all new parts and I would like to buy it all from you, please help me the guy completely ripped me off...thank you please help me...
Fred O'Reardon Hi Fred,
Im not sure if 2006 parts fit a 2001, it has been a long time since Ive worked on a DRZ. I would recommend that you contact the supplier for each of the parts you have that are in question, and ask them if their part will fit your application. I know that most of the parts do interchange, but cant be sure if everything interchanges. Also, I dont sell parts for DRZ's, but know a contact who does..If you are interested in getting that contact info, email me at MrDuhfactor at gee mail dot com.
What is the tank bag
Cant remember bud.... that was a long time ago....
hi i have big problem in my drz, maybe you can help me to fix it.
You can see my problem on movie from FazerFZR84, movie name is Problem z DRZ 400 E. Please check it
You've just seen everything I know...... Ha Ha :)
