About This Product
Bolt-in 2151cc kit (4.250 bore x 4.625" stroke). The S&S Cycle 131" kit includes big bore cylinders; pistons with rings; a stroker flywheel assembly and head & base gaskets. This is a perfect sleeper package that is bolt-in; so requires no case boring; headwork or flywheel balancing. Boosts your engine displacement to get some big numbers at the rear wheel; without advertising it. The kit bolts in; requires no machine work and keeps your bike looking stock for that "sleeper" approach. If you don''t want to keep secrets; a 131" badge is included for your cam cover. - Huge displacement increase means huge power increase - Bolt-on installation - Works with stock crankcases - Requires no case boring - Original engine serial numbers are retained - Powder coat finish matches factory finishes - Retains stock engine height - Includes 131" cam cover badge
