I have better pics I just can't get them tu upload. I can send to your cell tho chrome looks better than these pics show

my elevation is around 800ft ,,i checked the ring gap when i installed and they were rite on with Vito's specs ,,Doesnt make sence to me ..unless the guage i used to check my other banshee back then was off..Also, i checked my cylinder pressure B4 and after the rebuild with the same guage and according to it i went from 90psi to 100 psi with new bore,pistons,rings.. That blew me away. if ring gap is ok what could cause the loss in cylinder pressure..i have shearer pipes,,VForse3 reeds,,pro disign cool head(18domes) the jugs are ported on the reed intake,cross overs and exhaust the only port timing that was changed was from the piston being notched on the exhaust side.

i have a set of super stock in my shee. I am wondering if the notch on the ex. side would cause me to lose abit of cylinder pressure..I had .080 over piston with a 19cc dome on my old shee and im pretty sure it had about 185 psi,,on my new banshee i have same bore as the old shee but used vito's SS with the exhaust side cut and im only getting 155psi with a 18cc dome.
