yeah and the stock head , stock tank , stock pipes , and stock shocks on that other bike are soooooooo valuable ..... I think the only thing i'm sitting on is a cock
make your squish .040 " .
measure your sguish on both * SIDES* (not front n back ) of both pistons and use the smallest measurement of the four . Make sure you use all your gaskets . The old ones would be best cuz they're .... Squished
the front peices move the bottom shock mount out closer to the tire
the back one goes between the swingarm anf the lil linkage thing ... I think ........ O wait .. I mean I'm too fuckin busy for your fuckkin question use the fuckin search ffffffuuuuuuucccccckkkkkkk!!!
Dome design and compression ratio determine octane . Neither of those are affected by elevation.
I would buy 20cc noss domes if I didn't have a shaved head
Are you talking about chamfering ? You do have to chamfer the ports after a bore job . The guy doing the bore should do it . After a bore the port openings will have a sharp edge , chamfering is just rounding that edge so your rings don't snag it
those pistons are a poor mans port job . If your cylinder are also ported ...you have 2 port jobs worth of exhaust duration . Which will do what you are saying
you have to much sugar in your cake man ! Get rid of the pistons . Those pistons raise exhaust duration , if you have some porting done youmight have a drag motor
P.s.i doesn't have anything to do with octane . Your compression tester is just a tool to tell you how healthy you top end is .
I read a thread on another site that was about exactly this same situation . It sounded to me like 19cc *NOSS* domes are safe for pump gas . The way it sounded , noss domes are a better design than others . It also sounded like 19cc was boarder line safe . If this guy had a 64mm bore and you have a 66mm bore ...you may wish you would have stuck with 20cc
if you want cheap just shave your stock head go here http://www.sacoriver.net/~red/squish.html shave your head to make your squish .040" . Napa shaved mine for $35 . i ended up buyin a cool head tho and throwing that 35 bucks away
