Used to convert a stock 883cc or 1100cc Sportster to 1200cc. Gives 1:9.5 CR with stock heads. Requires boring of stock cylinders to the stock 3-1/2" 1200 bore only (see note). Other modifications are not required. Works with stock 883 cylinder heads and cylinders; stock cases do not require boring. Kit comes complete with forged pistons; rings; wrist pins and clips. Note: 1200cc cylinders must be purchased for 04-22 883 XL models. Stock cylinder liners of 04-22 XL models are too thin to bore to 1200 size.

It is of importance that a knowledgeable mechanic will install & make adjustments as required. The rider must follow standard break-in and riding procedures for overhauled engines.
