Hello.

I got a bad snake exhaust. Would the gianelli city power be less noisy?

What polini cylinder kit do you recommend?
I got:
polini case
Athena “racing” crank shaft
13mm carburetor.

Do I want a kit with cylinder head included, or is the original as good?

Guess I will order a polini cylinder.

the two crank shaft is of the same no-name brand and faulty dimensions. I tried with grinding down the camb by 2 mm. But that did not work.

Hello and greetings from Sweden.

I’ve had a continuous problem with two of my Ciaos. The flywheel comes off during riding.

today I measure and see different dimensions compared to other crankshafts. What happens is that the flywheel rest on the camb instead of fitting on the coned shaft. I will try to upload a photo later.

What can I do about t…[Lees meer]
