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?

I wrote to polini and they responded it is 250 degree Celsius.

anyway, before I got their answer I heated it to ~150 and it worked fine

Thank you for your reply.

I bought a Athena crankshaft, turns out it has the same problem as my Top racing cranks. And I’ve tried with 3 different flywheels.

I wrote to the dealer who said Top racing and Athena is the same manufacturer. Idk, feels like I just paid the double money for same product..

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.
