10mm Stroker Piston Speed

[Flash-FX]

HOLY CRAP!!!!!! Thats the lord, god, king of 2 stroke shiznit. I haqd one years ago and lent it to someone, never got it back, and still pizzed. Good thing i wrote down most of the formulas, it got me thru te rough times.
I'm downloading it right now and i am on dailup.

I hope this takes all nite,,,,,,,, it'll be worth it. since that book was written, the composition and design of pistons has come a long way. 4000 fps is the bottom line of racing engines meant to go WOT all the time

Sorry Pete for the threadjack, but the one file on ossatuning.pdf was "secret spec" from back in the day! The Yankee Z was a way FAST 2 cyl, 2 stroke bike. 2-250cc moto-cross cylinders together! This guy named "JR" used to modify them for the enduro riders. They were heavy gas hogs though. http://www.yankeetwin.com/ You old school guys might remember....Wait...old school is now.
