BikeJake Posted November 9, 2022 Posted November 9, 2022 Anyone know, standard liners? Surely paper thin by then lol.. 12.5—1 Cr maybe too much on pump gas or are these racing only? Can't find anyone selling who will pick up the phone. Like the extra torque but at no extra practical cost if poss... Cheers lads Quote
Gixer1460 Posted November 9, 2022 Posted November 9, 2022 A. Not a hope in hell! B. Will run but likely to pink under any reasonable load. C. Power and / or torque costs money, small amounts can be got easily but decent figures get spendy! 1 Quote

A lot of stuff you see for these engines from the states is designed for drag racing, so 20miles is 3 seasons racing. Quote

george 1100 Posted November 10, 2022 Posted November 10, 2022 I know of a guy that successfully ran 85mm pistons in a 1127 block with LA sleeves Quote
clivegto Posted November 10, 2022 Posted November 10, 2022 (edited) 1246cc is the biggest you can go with standard b12 liners you can fit bigger liners to the standard block some say they work better than the big cast blocks as they have more surface area (fins) for cooling.

Unfortunately not. Is a friend of mine that did 184bhp at the wheel with premium unleaded 100ron petrol. But it's the only pic I have of the engine Quote
