2001 Raptor 660r STARTER CLUTCH?????
 

um..... you better hope that you changed the starter clutch before it started to dump small pieces into the oil sump or in the tranny. check that out, don't replace it with the regular yamaha starter clutch, replace it with L&A or extreme aftermarket one-way because they last longer. Also replace the 52 tooth gear which is very necessary. well.... i hope that solves your problem.

Pieces in the oil
 

My husband said that he drained all the oil out today and it was clean so i guess were okay in that department, but yes i have been looking for the starter clutch kit (one way) and i think thats what were going to get. I am stressing though, with the starter turning over and it running if you roll start it, does that make since that it is the starter clutch and gear?

Yes it is very possible thats is whats going on.The starting clutch enages when engine is stop,its has bearing that kicks out into flywheel gear to grab hold of flywheel gear [this gear mate another gear to starter when starter is enaged], when engine cranks the bearing turns loose and freewheels while engine is running,So if your starter clutch bearing and gear is bad it can,t hold anymore which makes it slips while starting.. Atv doesn,t use this bearing and gear when push off only when starter is used..Good Luck.I hope this makes sense I tried to keep it simple the best i could, I didn,t won,t use the correct names for parts,may get you confused more..

Totally understand
 

THat makes perfect since!! thanks sooo much. We have a new starter clutch on the way, and the flywheel is off now so it should be quick to see if it works or not when it gets here, should be tomorrow! :) thanks again.

Need updates on raptor when finished.....

ITS FIXED!!!!!!!!!!!!!!!!!!!! It was the starter clutch. We got the extreme 1way starter clutch with the upgraded barrings, installed the kit and it works just fine!! :) thank you all soo much for the help!

Glad enjoy ride!!!!!!!!!! HARRY NEW YEAR TO YOU...

I replaced my starter clutch on my 660 but when I tighten the flywheel bolt the one way won't spin

Seems like you have assembled it wrongly, or, if aftermarket, you may have got a badly machined part. Take it apart and see if you can find what is binding, or fitted wrongly compared to the one you took out.
