2000 Yamaha Warrior 350 clutch slip/hard to find neutral and reverse...

[crash25016]

Hello, I am new to this forum but not new to riding or working on things. anywho. I have a 2000 yamaha warrior that the last time i went for a ride about an hour into the ride the clutch started to slip in 3rd, 4th, 5th, 6th gear . clutch cable had proper amount of play in it. I am running 10w 30 synthetic blend diesel oil (better anti-wear properties then gas oil) in it. Also when it is hat it wont go into neutral easy i have to shut it off or use my hand and its a pain getting it in and out of reverse. Would a new clutch fix all that or is there more to it that im not seeing. I took the cover off and roughed up the surface of each clutch disk and put it back together. Everything looked fine to my eye. The friction disks still had enough material on them so that they would not slip (in my opinion or so i thought). Any info on how to fix this or if i just simply need a new clutch would be greatly appreciated. Thank you.

not so sure that the oil you are using is or a wet clutch system,and that could be ur problem,check your sevice manual for what type of oil u should be using,if u need a manual,i can get u one,just message me with ur e-mail address and i can send u a link to a manual

the manual states that i should use anywhere from i think 5w 20 to 20w40 depending on temp. it recommends that i use yami-lube and any of them weigh oil. Thats all the service manual says to use

but the oil should work for a wet clutch application

[crash25016]

It should. Im just using diesel oil because it has better anti-wear properties then regular oil so it will help the clutch last longer among other things such as bearings and what have you. I also just got the quad a month ago and this problem just arose today which is pretty much the first time i had the quad on a decent ride and when i got it i changed the oil and filter and anything else that needed to be replaced.

your anti-wear additives are your problem.

Use motorcycle or quad oil- only that. ATV oil has friction modifers in it to make the wet clutch system work- car oil coats the plates and does exactly what you have described. Also, ATV oil is formulated for much higher heat since many quads and bikes are way hotter then even a diesel truck that's water cooled.

Go to the dealer and buy the right oil- hopefully your clutch plates are not ruined but no guarantees there.

Hopefully the problem will go away after you change to the right oil- if not, replace the clutch plates...

thak you raptor 8 for giving a clairafication on this and backing me up,i figured it was an oil issue

the way it's described that's about all it can be...
