anybody have any idea why it cuts out early like im over revving to early? only thing i can figure is the exhaust valve may not be opening enough, oh also how many ounces for a 40:1 premix ratio in 1 gallon can with yamalube no info on the bottle?

so it shouldnt make a diference, im going to get new gnarly or fatty or try welding. it does sound alot different than all the other 2strokes on the track sounds like an old school 2stroke

I would be very leary of it thats an old fourstroke handling prob not to good. It could have ben rebuilt but how long ago and how hard did he ride it, also how much of the motor was rebuilt. I would not buy it

there is a hole at the bottom weld point where the fmf logo used to be since it got ripped off, its about half the size of a button on a button up shirt will this make a noticeable difference in engine performance or not much. engine feels like it falls off to fast like it should have a little more in upper rpm of powerband, im expecting more but it just acts like its over revved. i know this RM has shorter stroke compared to yamaha could that be it or maybe the hole in pipe.
