i have a tuned k-star puch cilinder. i hope for about 8 hp. or maybe more. and i don't know if a stock crank would be good enough.
on our forum nobody knows how strong stock is so i decided to ask you

hi guys!

i'm from slowenia, so excuse me for bad langugae. i have a question for you. i'm doing a little project and i want to know how strong it a stock crankshaft.

so it you could tell me how strong is a stock crankshaft that would be great!

thanks!

can you tell me what the timing of polini cilinder is? how many degrees has the exhaust, how many transfer ports... that would be very helpful
