Default Re: 2 vs. 4 Stroke...

hrichmon, mechanically 2 strokes make more power then four strokes. For every 2 strokes of the piston the crank shaft revolves one full time. It takes 4 strokes twice the amount to revolve one time. My guess is that you didn't break in he engine enough and thats why you couldn't get past 25.
