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.
