    dirt bike clutch sticking

    we have a bike where the bike stays in gear the entire time pulling in the clutch wont work. it worked fine with lucas oil tranny fluid but it was dragging a little bit, we went to change the oil and for some reason my brother put 10w30 in it. i never new and i went to adjust the clutch but now it wont work at all. could the oil do it

    dirt bike clutch sticking

    reah we took the clutch pack off and wiped all off, we will pick up some real oil. I also heard you could use type f atf tranny fluid

    dirt bike clutch sticking

    its a kx65 and we went all the way on adjustment and nothing. theres not much spring action in the clutch springs should i see the plate move in and out when taking the cover on and off. bolts ti tight?

    it is kawasaki just the 06 model not 04

    2 stroke running hot

    hello my little brother has a kx65 that we just rebuilt the top and bottom end. the people before us put a different stator (the bike is an 04 and has an 06 stator). It also has a full fmf system and it was never re jetted for the new pipe. i looked up fmfs recommendations and they recommend just one jet richer main and one jet richer pilot. but that little change shouldnt mess with the bikes temp right? i mean theres no coolent coming out of the overflow but it is still a little hot. Im planning on getting one of those laser thermomaters things and seeing the engines heat, what would be a good temp?

    2 stroke running hot

    we did everything the manual said, 15:1 break in ratio and everything. i was thinking maybe the newer model stator is making the spark plug burn hotter? the 06 stator is different from the 04

    Kx85

    The would also check the shocks, should oil often needs to be changed before the seal starts leaking

    Kx85

    The first thing I would do is put a new plug in and run it for 30 minutes hard, plug should be a light tan on the electrode. Also I would put a new one in pin it in 3rd gear then pull the clutch and kill the bike. Cut the threads off the plug a preform a plug check. Also the suspension like you said. Others than that let him rip!

    Kx65 ignition problems

    So me and my dad have been building a kx65 for my brother. Retry much a 2018 on a ‘04 frame. So everything is done except rebuilding the shock and now it won’t sark. It did run but I screwed up the old stator trying to take the flywheel off. We got an aftermarket stator and put it on. The bikes sat since it ran and there is 3 or so spot rust areas and the outside of the flywheel isn’t magnetic enough to hold a bolt. I don’t know how much magnetism there is supposed to be. We took the boot of the spark plug and stripped it to bare wire and that won’t spark

    Yz85 high rpm problem

    I have one but for stuff like jets and electrics it says take it to s yamaha dealer

    Yz85 high rpm problem

    So my 2009 yz85 will chick if at about 9-10k rpm. I know it might not be good to run that high but at a face of a jump it’s sometimes necessary. I also have a pc platinum pipe.This is all we’ve done. Jets: 138 main(stock), 135 main(pc recommend),clip 3 (stock),clip2,clip4 Float: float was low 17.5mm (stock-18-20) Moved it up to 19 but no change. Spark plug: yamaha says to run a br10es but I run a br9es I think it may be the stator but Idk.

    Yz85 high rpm problem

    How do you test the stator

    Yz85 high rpm problem

    It runs great every where else but one at about 9-10k rpm it sound like it runs out of gas then cuts back on then of and so on and so forth

    Yz85 high rpm problem

    I never really rode hard until I got the pipe. Like I wasn’t very good got the pipe then later progressed to be able to ride better. I will try putting the stock pipe on but I couldn’t really think how the pipe would be the case because changing jets should effect it

    S0......Honda isn't the only one...

    Sounds like the ktm 300 and 250 xcw tpi vs carb. The tpi was smoother mid range but was jerky and not smooth down low, as the carb with good jets was smooth down low and all the way through top, injection hasn’t been around in dirt bikes that long but trust me give it time and it will replace carbs on all bikes. Just like cars fuel injection replaced carbed cars

    S0......Honda isn't the only one...

    I think it’s from 2018 I looked at a few 2018 dyno results and they where all right about the same. I also saw a costume build Honda 250 vs stock 250s and it took the lead in mid and top but was last down low, 250s they rev real high anyways and if you are okay with shifting more and reving higher that might not be a bad way to go

    Yz 85 jetting question

    So I have an after market pc platinum pipe. For a while ride with stock Jett’s but then I switched to the leaner pilot main and clip position. But I’ve tried every jet setting I could with stock and leaner Jett’s and the bike wants to choke off when WOT and when reving in neutral it doesn’t want to rev out and sounds like a 4 stroke rev limiter. There’s just no over rev I think it’s also worth mentioning that I’m running a ngk br9es when the book calls for br10es. The 10s foul with stock Jetts

    S0......Honda isn't the only one...

    That was informational but I’ve always wondered why a unicam design. Why unicam over DOHC doesn’t the double can respond better at higher RPM. And if the 450s don’t have the power problem just because they are 450s wouldn’t that mean that the crf450s could have even more power than it does now, because it’s the same engine design?

    S0......Honda isn't the only one...

    The only reason I see for twin exhausts is less back pressure but a less restrictive single will do it to. Plus aren’t motorcycle exhausts short enough anyways that the pressure difference wouldn’t be noticeable

    Not shifting into gear good.

    I could not tell you if that worn edge would be enough to cause problems but I know if a snap ring is missing in between two gears it can cause the gear to slide a little between the higher and lower gear. This can cause a false neutral. It’s a long shot but happens to my brothers 65

    02 CR250 hanging idle?

    Get it fixed?

    Yz 85 jetting question

    I started thinking it may be the float because the stock jets fouled plugs in the beginning but it ran good, now stock jets do the same problem. I’ve been in the carb a lot in the past few weeks so may have bent the float. That’s what I’m thinking
  24. Hunter743

    Yz 85 jetting question

    I never checked the float, I ruled it out because this problem came with the new pipe. I will check Those are the Jett’s I bought
  25. So me and my dad are very mechanically inclined, can do a fork rebuild in a hour and a half and a top end in 2 hours (4 stroke). We are planning an starting a shop out of our home ( we have a big shop space) but wanted to know if there was any legal permits we need. We would talk to our insurance but since it inst a business would we need to pay taxes and all this fancy stuff. And the person getting the bike worked on would know that we are not professional so signing the bike over to us to work on he takes responsibility for giving it to us. obviosly we would be responsible but since he knew we aren't professional do we need a permit.
