These aftermarket kits are put together by ourselves from our detailed knowledge of these engines. They are exceptionally well engineered and represent excellent value.

Crankpin diameter (standard size) 2.2484/2.2492 "

Please note, if you have the chromed liner version of this engine, we add £50.00 to the overhaul kit price. (See option photo to help identify your liner type).
