Scooterotica

Heres the link you wanted http://www.twostrokeshop.com/two_stroke ... ngines.htm

thats a very interesting site,
i referred to it on our great debate that was about primary compression ratios...
high primary compression (hpc) /low primary compression (lpc)
check out the crankwebs they are using...

lots of other good stuff on there that could possibly be usefull

pistons,and their weights ,cylinder head designs,
porting configurations etc....all good interesting stuff....

Had my eye on those Toroidal heads for a while - Considering this is the place in the motor where all the action takes place, combustion chambers don't seem get much attention bar squish and compression ratios.

Same thinking. I looked over this (Thanks Sean) and other stuff while looking for surface coatings & treatments for piston rings...

This was another good article, a little dated, but it still contains some good info...http://www.vintagesleds.com/library/man ... effect.pdf

Thanks for the link very nice barrels, Lots of top gear at top dollar.
Those pistons look like the biz
