I have been looking for parts for an engine build on. 1982 GS1100G. There are a lot of piston options out there in both size and compression. I am trying to figure out how big can we go on the stock cylinder/sleeve before needing to resleeve. I'm not saying I am going to just hog it out to the max, I just want to know what my limits are so I can weigh the costs of different options. Thank you.

Hi gents. Anyone know the max liner o.d. you can install in a stock B12 case? I am trying to make a silk purse out of a sow's ear with the p.o.s. 1127 block I bought off of that site. Had 81mm bores, but they were worn out. I figured with winter coming on it might be a good time to turn it into something useful for next wrenching, errr, riding season. I found a company called Melling that makes some pretty affordable liners for re-sleeving. They will build to suit. Thanks.

After starting racing with a stock 1127 with 120 RWHP several years ago I am now campaigning a 1277 with a best run of 173 RWHP (done on the same dyno). Plenty of life left in these old oil cooled beasts. DYNO 1277.pdf
