My dad is a wimp and isn't a mechanic at all. I am the black sheep. Still thumbed up your vid! Love how clean yours is. I know this is an older vid, but I'm going for orange on my 2002. Thanks for the upload!
Dark Sorceress Zyra: You're welcome and thank you. I do try to keep her as clean as I can.
@@fwh79FOXR6 Oh that is so awesome, I'm so glad you still have it! I have my R6 in the living room. Hahaha
@@darksorceresszyra9467 In your living room... I'm jealous!!! Keeping your bike in a temperature controlled environment, is probably the best thing you could do for it.
@@fwh79FOXR6 Yaaas do it!
According to the engine sound it looks like one cylinder getting not enough gas or may be it is too rich but not the all, it is better remove your spark plugs and check which one it is and make the necessary changes rather than enriching the mixture in all four.
after installing the new jet kit and initially having pilot screws only 2 turns out, did you have decel popping?
Timothy Tendick: I honestly can't remember if there was pop or not. I would recommend going 3.5 turns out though. 2 turns is most likely a lean mixture.
Weird question but what is that engine whine? I know a lot of street bike have it but my 01 R6 doesn't have it. Should I be concerned.?
Bronson: Give me a time stamp in the video and I will try to answer your question.
fwh79 around 28:30 that very distinct whine that many street bikes have
@@bronson2585 Is your R6 stock?
fwh79 yes
@@bronson2585 I noticed that my bike sounded different after enriching the fuel delivery. I don't think you have anything to be worried about with you bike. This video might be of interest to you: czcams.com/video/VzpqJMNdqpY/video.html
R6 and Sport Bike fans, please subscribe to my channel. I need your help to break 1,000 subs! Thank you!
Hey man I have a stock 2002 Yamaha r6 It’s been giving me hell. It was doing what yours was doing with leaking from the lower exhaust and smoke from the exhaust. I cleaned my carbs and I’ve adjusted the air/fuel mixture screws 2 1/4 out but it still dies after running for a little bit. Do I continue to lean the bike out by turning turning my air/fuel mixture screw in? If I’m running rich wouldn’t I turn the screws in? Btw I have factory jetting my bike is stock 19k miles.
Jordan Anthony: Did you check your float bowl needles? You might want to try 3 turns out on the pilot jets and make sure that your float bowl needles are not destroyed. If the needles have never been replaced, they are probably the source of your issues.
Hi, first of all nice video.
Second, my R6 has a little stumble.....but it's at 12k...it goes normally but at exactly 12k it decreases for half a second and then goes back up again.
Thoughts?
Pedro Ferraz: Could be an ignition issue or a fuel problem. I would start with the fuel system. Install a new fuel filter and use a fuel system cleaner. Be sure to use the proper amount of fuel system cleaner. Most fuel system cleaners are designed to be mixed with 20 gallons of fuel. Be sure to pour out the proper amount. See how that works for you. If that doesn't solve your problem, pull the spark plugs and inspect them. You may need new spark plugs and/or new ignition coils. This video may be helpful to you: czcams.com/video/oJxGjMlV9BA/video.html
I know this is old, but the stumbling at 6K is common on these. its it from too lean?
John Grimes: Yes, it can be and I would say the lean factory tune is the number one cause of it. However, there are many things that may cause stumbling.
fwh79 that’s what I’m learning. Picked up an ‘02 with 12k miles an Ivan’s jet kit and a Hindle slip on. It stumbles around 6k unless I’m fairy chill on the throttle. Gonna use a dynojet kit, resynch and go from there- fingers crossed!
@@johngrimes3117 I have read stories that most of the jet kits are kind of wonky for the Gen 1 R6. My Factory Pro kit seems to be working out just fine though. However, it is getting tough to find the Factory Pro jet kits now. I would still think that any jet kit is better than no jet kit... but I have only used the Factory Pro kit, so I can't really speak to that situation. It seems like 9 times out of 10 the stumbling problem is caused by bad ignition coils. My bike is on it's second set of coils now.
czcams.com/video/bvN-o_95cwE/video.html
Like I stated earlier, a stumble could be caused by any number of things besides ignition coils. Could be a vacuum leak, bad spark plugs, dirty air filter, dirty fuel filter, dirty carbs, out of sync carbs, improper pilot jet adjustment... the list goes on and on. At this point in time my bike seems to run very well, even when the temperature drops and ruins the air/fuel ratio. These carbed bikes really need much more attention than the injected bikes do. I will say, the effort is well worth it though. Let me know if you have any questions that I might be able to answer for you. Good luck and please come back and let us know how your bike is doing. These comments help other R6 owners get their bike running on "kill mode".
fwh79 thank you sooo much and will do! Plan on pulling the carbs after Xmas and checking everything. 2 questions though- how is the float height measured and how to test the coils on my VOM. My thanks in advance!👍🏻
@@johngrimes3117 This video is about the coils czcams.com/video/dmDDz1CaGfA/video.html Setting the float height is fairly simple. I'm sure you can find some videos on CZcams about it that will explain it better than any comment I can make. You can check the float height when you have your carbs apart but I doubt you will need to adjust it. You really won't know if it needs to be changed until you get all your carb work and tuning done. The float height really affects the 2,000 to 3,000 rpm range.
I was at 3.5 turns out, idle was pretty smooth but would stumble about 7-10k rpm... acceleration was good from a stop until the change in the powerband... any Suggestions !?
Could need to shim or "reclip" the needles but it sounds as though you have an ignition coil issue. Shimming the needles is much cheaper, I would start with that. There are videos on CZcams that show you how to set the needle height, I don't have any videos about it. I do have a video or two about the ignition coils. I'm on my second set of new coils right now.
Was running fine until I rebuilt the carbs, only changed out the float needles, pilots screws and Bowl gaskets... Currently have R1 jets in from previous owner, never had this issue before, still need to sync them also...
@@christianjulian6305 Did you swap in the R1 jets when you did the carb rebuild? How old are your spark plugs?
No came like that and was running good before I pulled them off for tje gasket job... Im at 4 turns out now and ran some seafoam thru, seems a lil better now
@@christianjulian6305 You might have a float that isn't seating a fuel needle just right... these carbs can be touchy sometimes. Some times light tapping on each of the bowls with a rubber mallet can help knock the floats into place.
Is more easy with carburator out of the bike
Isra: Sometimes it is. You can do it either way you want to.
What's the maximum pilot jet adjustment I can go to? I'm at 3 now and still has a slight stumble when I blip the throttle. Needs a touch more but I'm afraid of going to far
Gear1993Head xxx: You can keep going. I can't exactly remember, but my carbs are at 4 or 5 turns out now.
@@fwh79FOXR6 thanks I ended up stopping at 4. ran amazing after adjusting the needle up one and the pilots.
@@Gear1993Head Getting the carbs dialed in right, can make a night and day difference on these bikes. Glad to hear you found the sweet spot.
Dear man,I have on my r6 akrapovic exhaust,and pipercross air filter,and after sync carbs on high rpm i have feeling need more petrol,watt you think?tnx
@@siki7044 Even a stock R6 benefits from pilot jet adjustments. If you have an exhaust, you should definitely adjust the pilot jets to a richer setting.
im so confused, mine doesnt have a screw it looks more like a plug on mine also 2000 r6
That’s a cap that you need to remove to access the screw
By turning the pilot Jets you are in fact tunning the carbs and to do that you need the carb syncing tool. By doing it this way you really don’t know how well, rich/lean each cylinder is running. You may feel the bike performs better but you really don’t know. You may actually make it run even better than you think. Also using a carb syncing tool will save you from having to remember how many turns in or out you made. That is just my opinion. Also you won’t have to put everything back together time after time just to “feel” if the bike is running better or not. There are two ways to sync a carb, one is by turning the pilot Jets and the other one is by adjusting the butterfly valves in the carb. Both must be done to make sure the Engine is tuned right.
What he did was increase idle fuel mixture. This does not require a carb syncing tool (manometer). Sync tools are used when adjusting the butterfly valves to create an equal vacuum between them.
I did mine in each carbulator 3 1/2 + 1/4 turn. I don't know how thats call. but 3 turns and half plus 1/4 or the middle betwen 3 1/2 and 4. What I did is that I adjust each one till the end and star unscrew them slowly counting the turns.
3.5 turns out seems to be the sweet spot. I'm sure every engine is different so it is something that you have to play with. I want to try going back to 3.5 turns out (think I'm at 4 now) and re clip the air needles richer. Gotta wait for the warm weather though!
@@fwh79FOXR6 3.5 turn out with open exhaust and open air filter or stock all?
@@siki7044 I would start at 3 turns out for stock and 3.5 for bikes with a high flow air filter and exhaust.
@@fwh79FOXR6 I will try.Tnx man
@@siki7044 You're welcome
Stupid question but I'm learning. I recently cleaned my carbs and just put in the air/mix screws in the same amount of turns as I took them out. When you say 3-4 turns is that from completely tight? Because it took me 17.5 turns to get them completely out and replace the rubber parts.
Yes, you are correct. Close the screws completely, then count the full turn of the screw out 360 degrees. I would suggest starting at 3.5 turns out. When I made this video I had bad coils in the bike which were affecting my results. I highly recommend doing a carb sync when you get the carbs back on. Even if you did a bench sync.
fwh79. I am actually looking at your other video now, my carb sync pro came in today so I can do it this weekend.
That's good. I think you are going to be very happy with the results. A little tuning goes a long way. Let me know how it goes for you.
fwh79 obviously not very well 😅
I need somebody to work on my bike
John Perry: What kind of bike do you have and what is wrong with it?
What the hell? Have you ever heard of a carb sync tool? That is NOT how you sync carbs....
Benson West: Did you read the title of the video? Does it say carb sync... or pilot jet adjustment?
