Some dyno charts to give an idea

This is a LT500R with a custom shearer/q pipe, stock carb, cut head, mx ported, boyeson reed.




This is a banshee with fmf, trail port, cut head, vf2, single 38mm pwk carb, +4 timing




Notice the a/f curve, see if the guy has that, and use it. They are worth it for tuning. Also need to make sure the guy knows how to read the curve.
