The Secondary Clutch was sticking and was completely stuck with the -19 temp at the Yamaha Dealer. They serviced both the secondary and primary. I was just advised by another OC member to do this every year including changing belts. Link to comment Share on other sites More sharing options...

I have never heard of the secondary clutch sticking closed causing the engine to accelerate such that it gets out of control. Glad you are ok. Always a good idea to inspect and service clutches and belt. Link to comment Share on other sites More sharing options...
stoney Posted January 30, 2019 Share Posted January 30, 2019 If the primary clutch is sticking closed, it will cause the sled to move at idle, kind of like installing a belt that is to tight.....I am trying to think of how if the secondary was sticking open, if it would cause the same thing, but all that I can think that it would do, is create a belt that is super loose in which case the sled will not move, similar to your belt deflection being off by a large amount. Regardless, clutches that are not maintained or working as they should, could cause this....glad the cause was found. Link to comment Share on other sites More sharing options...

I don't know with a 100% certainty, but I'd say the dealer doesn't know either and just assumed this was the problem? Again, YF, are you a member at TY and did you ask/post over there?
