Here I have a used JE 11.5:1 and a 13:1 piston,04/05. 11.5 : 1 Piston was used for about 15 hours. Uses 91 octane fuel, Only switched out to go to race fuel and higher compression. Needs new rings. 13:1 Piston has the same amount of time, uses race gas. Never had any cylinder damage on my bike with either piston. I got new crank and a different compression piston for this years build, Asking $55 each Shipped or $100 for both shipped
