Was wondering if anyone has encountered this.

After getting my 250 quadrunner 4x4 up and running, after replacing the one way clutch bearing so my electric start will work, when i put it in gear when its idling , it jumps forward and wants to go. I have the idle down low , and it still does it. I changed the oil with new 10w 30 quaker state. I got the machine used and dont recall it doing it when i took it for a test ride but i cant remember. Does that sound like the clutch plates are sticking or bad? Is the quaker state oil im using causing this?

 

may be the oil, , get some 4 stroke motorcycle oil made for wet clutches

 

Ya, thats what im thinking
