The 790cc Big Bore Kit includes a custom made, forged 9.5:1 piston with rings, wrist pin and circlips. A custom made multi-layer steel head gasket, OEM metal base gasket, tensioner gasket, and cam bolt lock plate and a ProCycle specific big bore cylinder sleeve.
Built cylinders with 790 sleeves installed are usually in stock, but we must have your original cylinder sent to us as a 'core'. These cores allow us to keep up this program and it is nothing more than an exchange - we give you ours, you give us yours.
This Kit Includes:
- DR790 Big Bore SLEEVE ONLY (requires your cylinder to be bored and sleeve pressed in. Your local machine shop is the best place to ask for this service.)
- Steel Base Gasket
- Steel Head Gasket
- Cam Sprocket Plate
- Tensioner Gasket
- 110.6mm DR790 Piston
- Instructions with DR790 Stickers
