Setting problem

hello, ive been using mazzuchelli 60mm crankshaft + cylinder kit malossi 221 single ring, is it the carburetor 2424 enough to support petrol consume, because its high rpm and somehow over rpm 8200 i heard knocking sound, afraid its gonna jammed, ive been thinking to upgrade with mrp 36mm manifold + mikuni tm 35mm, the question is, is it 2424 si carburetor not enough to support the 60mm long strokes shaft.

Hello amenajhan,

wir that setup we would offer you a PHB 30 carburator.


Kind regards

Mario SIP
