ESR 265 PV Specs????

[stever250r]

I just purchased a ESR 265 PV cylinder that has some very slight damage to the bore and needs to be replated.

I have found the company that I want to do the work but I dont know all of the information I need to put on the work order sheet.

Can anyone give me the original specs on this cylinder?

Bore size?
Piston ring clearance?
and the Wiseco part number for the piston that I need to have them order?

Im sure I can call ESR but they are closed and I wanted to get the cylinder on the mail tomorrow morning.

86 style 80 over piston would be what I would think. Did you use a spacer plate on your motor or not? And do you have a long rod or short rod. Most esr kits are for a short rod piston, I think they use pro-x pistons not wiesco.
