would it be safe to bore a gsr block to 82.00mm with stock sleeves? just wondering thank you..

 

yes, but you cannot bore it again after that

 

Seen a stock GSR bored to 83mm when I was overseas.

 

83mm... and i thought 82mm would be to much...

 

Most people here will tell you 82mm is the most you can bore a stock GSR. But like I said, I've seen 83mm done overseas and it's pretty common there. I'd go 81.5mm if you can get away with it, so that if you need to in the future, you'll still have room to bore it again.

 

81.5mm would be a safe limit
