it takes almost double the cc's for a 4 stroke to equal the power of a 2 stroke.
has to do with 1/2 as many strokes..... 2 stroke makes power on 2 strokes compared to 1 for the same rpm's as a 4 poke
add in the turbo effect of a 2 stroke pipe and .....BRAAAAAAP
Are you looking to have fun with this power, or just have a meaningless number?
Because even with less hp, a blaster is better than say... a 500cc 4 stroke. speaking from experience, 4-pokes are bulky, and have speed but not handling
