[QUOTE=ScrapingFloorBoards;14106964]Are you running the stock Pistons still?[/QUOTE
It's a screaming eagle forged flat top. The factory piston is cast. I was able to use the piston and achieve 10.7 to 1 comp due to the dealer installing SE Kompressor heads on the street stage 4 I upgraded to when I bought the bike. They had those heads paired with the 10.5 comp dome piston that equaled way to much compression. So over the winter I dropped the compression with a factory style forged flat top, gave the heads to Jim at Megaflo, 55mm HPI throttle body w/5.32 injectors, a Reaper 594 cam and got 122hp/120tq. The SE kit dyno'd 103hp/114tq.

Nice numbers (for the latter setup). Why, oh why, do dealers install setups that anyone that knows even the basics about motors would know not to?

Thanks Man
They wanted to keep the engine bicolored after I told them I didn't care. It had 11.5 to 1 comp. took me alot of recording on my sert to eliminate most of it.
Then just decided to do it right.
