Will it fit
 

Will a 929 motor fit straight into a 954 frame without any minor enginerring?

No. The swing arm mounting is different.

But with some modification, it could be made to fit.

Thank You
 

Hi, thank you for the reply - by chance would anyone have a step by step on exactly what would would need to machined?

I think the 954 swingarm is wider than the 929 motor. You might be able to shim it to fit.

Why go with a 929 motor instead of a 954? Seems like a step backwards.

Thank You
 

Can get a 954 bike with badly blown engine and can onky find a 929 motor here is S.A.. so not sure whether to buy and do conversion
