I bought a used engine with esr cylinder. threw it in and runs great.. just curious if there is a way to tell if it is a drop in esr cylinder or if it is a bored case cylinder without pulling it? not really a big deal, just curious. Im running it for playing around but Ive got a 350 cyl I could throw in it if it was bored cases..

look under the bottom of the reed cage area, there should be some info wrote into the casting. let us know what it says.

the C9 means cleanup "9" porting, not full trx9 ported.

since that is all he wrote on it, you will have to pop the head and measure to see what bore it is.

I talked to Eddie and he said I'll have to pull the cyl to see if cases are bored or not. Maybe this weekend.if they are I'll throw a 350pv top end on it.
