I was wondering, the Savage is counterbalanced.
If the piston is lightened, so should the counter-balancer, unless this is only about "more steam", in that case remove the balancer and gain even more HP.
W/ the stock counter-balancer I expect it will want to buzz more, not much fun on long rides...just a hunch.
Didn't Lancer remove his counter- balancer?

It looks like for a couple bucks extra (10-20) we can get them lightened and coated, i'm not sure i need the coating, but lighter would be nice, maybe give a few more rpm. Also not sure if rings are included in the price, i'll see what their's cost included. work is keeping me busy right now but i will update as soon as i have the information. Unless someone else beats me to it. Then i will just buy the piston.

Man, every NHRA Prostock racer out there is running sky high compression, pushing 16:1, on VP-C25.
Quote:At low RPM's, slower burn is better. As RPMs increase, less fuel has time to burn on compression stroke and more power is produced with remaining fuel after TDC.
Again, keep in mind this a$$umes all things are equal. You can retard timing at low RPMs to counteract, but remember: the higher the compression ratio, the more energy the pistion bleeds on the compression stroke.
Sure they have variable timing but that is a given. Compression is good, octane and cooling are the limiters as to how much compression you can run, but more is always better for HP. Suzy has the patent on the TSCC head and it works better the more you squeeze it, ask someone like Byron Hines.
Also 8:1 practically sucks. If decking the jug will move the cam a little I don't think it will hurt perf much.
Back in the day when EPA 1st started killing compression, smart guys were tweaking the valve overlap to effectively bump up compression too, but w/ our air-cooled 650, I would expect problems to arrive as you approach 10:1, on a streeter. Remember (cylinder) volume is cubed the as dimensions go up. Think the 650's OHC will suffer w/ the extra heat as opposed to a pushrod OHV (HD) design.
Come to thinkof it, how many bikes today have similar swept volume that are OHC AND air cooled as opposed to water cooled? Now I gotta go look...
Recall how the original GSX-R was oil (not water) cooled 8)
