The stator in my 1991 Yamaha 650 super jet went out. Replaced the stator, starts just fine but will not accelerate and bogs. Replaced all electrical components, and carburetor. Same problem. I thought I had a bad new stator, changed the stator again, same problem. Is it possible I am installing the stator incorrectly? It seems fairly straightforward, I aligned the timing in the middle. Woodruff key is installed and intact.
I am at my wits end, please help.
