Brief history:
Got a 93' YZ 125 with a shot top end and in need of lots of repair.
After replacing the topend and chaging the fluid, brakes and misc parts it finally runs good except the clutch is not right.
I cannot start the bike in gear with the clutch depressed when cold.
It seems like the clutch will not release. I have adjusted the cable to spec and even have more tension then recommended to pull it more then required to release.
I pulled the clutches and steels apart and the clutches look like new and the steals were spotted from the clutches from having sit so long. I used 400grit wet paper to get the steals looking like new. I checked but the steels and clutches for warp and they are perfect.
I put the whole thing back together and it worked good with no oil in the case. but as soon as I added oil the clutch seemed to not want to release almost like the oil made the clutches stick together.
I originally had Mobil 1 5W30 in but went to yamaha and the guy gave me a quart of 5W30 yamaha 4-stroke oil.
Is motor oil supposed to be used where it calls for 5W-30 Transmission oil????
So I start the bike and let it warm up.. (I have to start it in neutral) if while running I put the bike in gear the engine dies.
I am able however to give it some throttle and kick it into 1st while holding the brake and clutch and the engine boggs and the bike jumps and then it kinda heats up the clutch to where it acts normal... After its 100% warm the clutch acts normal and I can shut it off and restart like it never happened.. but as soon as it cools down I have to go threw it all over again.
Also I want to say HI to everyone as this is my first post.
Thanx,
