Smifee Posted April 9, 2023 Share Posted April 9, 2023 Whats the max overbores on oil cooled barrels. Guessing the bandit 1200 are best barrels? Is 1216 the biggest you can get with stock liners? Is it much work to have bigger liners fitted? Quote Link to comment
DAZ Posted April 9, 2023 Share Posted April 9, 2023 I believe you can get a 1246 kit for b12 barrels as the liners are slightly thicker than the 1127 version can't help on the cost of big liners but don't forget the crankcase will need machining to suit the bigger cylinder spigot and possibly external oil lines too if the machining causes issues with the oiling system 1 Quote Link to comment

Gixer1460 Posted April 9, 2023 Share Posted April 9, 2023 I thought that 1371 was the biggest of the overbores before stroking to get capacity increase? Isn't it 86mm bore in a big block - the APE ones were nicest but very rare now! Quote Link to comment
clivegto Posted April 10, 2023 Share Posted April 10, 2023 (edited) Crank cases don't always need opening out for bigger liners the bottom of the liners can also be reduced to fit the crank cases like these 1277cc ones. Edited April 10, 2023 by clivegto 7 Quote Link to comment

Liners got to be getting pretty thin I would think at 86mm. Quote Link to comment
