Thread: Cyl. Boring
02-15-2010, 12:08 PM #1
I have std. bore cyls. on a 94 slt740, & Im doing a top end job!. My question is do I just order .5 over pistons, or do I have the machinist tell what size to get?

how bad is the scoring? If you get .5 over pistons and take them and the shop with the cylinders. they cna match them up

I thought that I was going to get away with just honing. But upon further exam, I found a problem on bottom portion of cyl. Its on the exaust side about 1 in. up from bottom.Thanks for the info. Thats what I will do, just take pistons & cyls. to machinist.

post a clearer pic. that far down on the cylinder wall will not effect compression. you might get minor blow by into the crank case on the downstroke

Safeest bet is to take the cyls to the machine shop first. Let them figure out how large oversize you will need to go.
