Description
9.5:1 compression. Converts your XL883 or XL1100 Sportster, re-using your stock cylinders, on 86-03 XL only, to 1200cc. Complete with reversed dome forged pistons, rings, wrist pins and circlips. Will install without modification to cylinder head. Piston weight approximately the same as stock, rebalancing is not necessary. Compression around 9.5:1. Tests have shown a 26% power increase on 883 models.
Note: For 04-up XL models 1200cc cylinders must be used. The stock 04-up 883 cylinder liners are too thin for boring to 1200 size.
