My brother has a 4 stroke dirt bike, it’s pretty quick, but they may do funky things with it’s gear box too…. getting 4 strokes to rev high takes a good balance and a short stroke, if the inertia is low enough, you can probably spin one to 13000rpm. Just because my 2 stroke 372XP works well with an 8 pin sprocket, doesn’t mean that I’m required to use that same 8 pin sprocket on a 4 stroke saw turning 2500 rpm’s less. How they got these small engines to crank so high is beyond me, but since the valves are due to be adjusted at 26,000 miles and a 2 stroke engine is junk at 8,000 miles, I think longevity is where the 4 stroke versus the 2 stroke chainsaw will really pay us dividends.
