Most owners just want the gawddamned bike to start under all conditions. > >PS it's not a "tweak the carburettor", that's all fine, it's a "tweak the >linkage, there's an adjustable stop" Oh, so the linkage is not part of the carburetor bank now. I'll have to remember to be pedantic the next time I need to tweak my carbs. -- Message posted via MotorcycleKB.com http://www.motorcyclekb.com/Uwe/Forums.aspx/yamaha/200708/1
