[Benn]

Hey everyone, i need your help  . I'm looking for a crankshaft for my moped that would hold 70cc high end cylinders - 77cc big bore cylinders and i found - Top performances Racing 85mm concord 39.2 stroke crankshaft. Does anyone have it? Or has some info that would help? Main question : Is the crankshaft any good? Does it hold high end - big bore cylinders or shoud i look at another one? Thanks.

I spoke with you via email, but the 44mm stroke version worked for me in a TPR 86cc revving to 14k+. The 2 I've had were pretty well true out of the box.
