Description
Long stroke optimised crank for 2000 Nord and Twin Spark engines.
The stroke of the crank is stretched to 94mm whilst ensuring it fits the block without modifications, increasing it by 5.5mm to 94mm, which gives just over 2100cc with 84.6mm bore, or just under 2300cc with 87mm bore. Resulting in Twin Spark engines capable of producing 230-240BHP and Nord engines producing 220-230BHP.
weight has been removed where necessary, with the big ends bored hollow to reduce centrifugal weight. The counterweighting has been optimised with very specifically shaped and sized webs to ensure perfect piston & rod counterweighting at high revs. The result is a long stroke, increased capacity crankshaft that revs up faster and is more free revving than a factory crankshaft.
Ground and super finished these should be in display case.
We have a limited number available and can be purchased with long rods and matching pistons to fit you engine build.
