so a friend swings by and tells me he did a valve adjust, set timing and syn carbs, and his performance and mpg went down hill.
so I take it for a ride, man gutless for a 89 R100rs, gutless.
I did not check his valves, nor mess with the carbs, but did check his timing
where he set hsi timing with his light does not agree with my light.
he set it so the z is lined up, with my light the z is all the way at the top of the wiindow, just barely visible
wonder whos light is right
his is an acutron ?
mine a old craftsman
so we set it with my light, havent heard back from him since this afternoon , when he left
I guess too advance would effect power and mpg. but it did not ping or rattle like a machine too advanced
