how to make a two stroke parallel twin last longer.

[gofastclint]

I was looking at parallel twin two strokes and I found that parallel two stroke twins with a 90 degree crank as opposed to a 180 degree crank last longer and also deliver power smother. for this reason the worlds most advanced two stroke parallel twin features this layout, the KTM 250 Moto GP engine. the site quoted "The 90° layout in a parallel-twin offers a reduction of peak rocking-couple forces of 31%" that's huge! I can see this translating to a longer gearbox and prop life in the Rotax. there are many places that costom make two stroke twin cranks to any specs and you will need to modify the electrical system, but 31% reduction of peak rocking force, I bet that would save alot of components in the long run.

 

the site I got the details from is great, the guys involved are two stroke specialists and one is a moto GP engineer. The Two-Stroke Shop 2-Stroke Shop TSS500GP engines TSS500LC
