Well that stinks, what a turd ! I guess mine is one of the older versions.
When they changed the crank bearings they really created a ton of problems ! This is probabley the reason RB stuck with the smaller crankcase and bearing in most of their engine's . I know the new C6 with the turbo plug is an incredible engine ,and worth every penny . I think I would purchase one of these before I bought any other Novarossi . They have been going down hill I think after the hostle family fued they had over there.
