I let it run and went in and got the carb cleaner sprey and came back out and revved it a few times and it's running like doo-doo sounds like a spark plug is trying to die on me.... in and out half the time...
I sprayed the left side carb and no change at all... i went around and sprayed the right side and it immediately picked up the other cylinder....
and seemed to run much better.....
I think I found the problem.... butterfly shaft seal !

Bob........... 
....
and yes I think it is the right hand side that keeps trying to die on me (cylinder wise)
the idle was like 100 RPM when I turned off the choke.... because the right cylinder quit firing.... I spreyed carb cleaner on that side of the carb and that cylinder picked up and ran on both cylinders......
it ain't supposed to do that !!!!!!
so I at least know where to look ! |
Be very careful here, you are entering NO-GO territory......NO factory breakdown exists for "butterfly shaft seals" ......therefore NO parts are available. Note the screws on the actual throttle butterfly must be removed to remove each shaft. As they are factory installed, I'd be highly doubtful of leakage on (as you've noted) such a low mileage bike. Frankly....a mistake waiting to happen.
