S&S 4” Big Bore ‘Sidewinder” kit
S&S has a new bolt-in 4-inch big bore ‘Sidewinder’ kit available for Twin Cam 88s.
The company says “no machining, no rebalancing, just bolt in pistons and cylinders in place of the stock items and the kit will take 1999-2006 Twin Cam 88 engines up to 100ci, and 2007-later (except 2017 touring models) become 110ci monsters!”
S&S say that installation can be done with the engine still in the bike, and that the kit works well with stock cylinder heads, or, for even more power, S&S say they can CNC-port the heads for their dealers.
Available in color-matched silver or wrinkle black powdercoat finish, the 10.5:1 compression “makes for a very ‘streetable’ and dependable engine that also responds well to performance cams.”
