Hello,

I do mazzu racing crankshaft original px125.

Ignition must be stopped?

Now factory setting, the engine is not going well

There is no power, not turning well.

Exhaust sip road1

Szasza

Original px125 cylinder, can be used mazzu chrankshaft racing?

What can I expect original 125 cylinder

www.sip-scootershop.com/en/products/racing+crankshaft+mazzucchelli+_45000000

With original engine e.g. cylinder and exhaust the advantage will be none

I understand

Now I put it on, but do not function normally.

Small speed and no power.

High speed starts, it runs beautifully.

I can not find the error.

Carburetor 20/20, 45/140, 102

Next year I want to pinasco177, so choose now mazzu racing crank

But now the problem is with him
