Defective cylinder head
I bought the first Polini 70 cylinder kit in October 2025. After 3 months, the circlip on the left side of the wrist pin came off and I destroyed everything. In February I bought the same cylinder kit. At the end of May, the booster stops. I open the cylinder kit and the same defect: circlip on the left side in the crankcase and the cylinder broken and the piston destroyed. What should I do?

Mentore4 months agoSince this is material that cannot be homologated for road use and cannot be used outside of competitions, there can be no legal warranty covering that type of failure.
I’d recommend contacting the manufacturer directly to see whether they provide any kind of compensation for a type of failure that you consider recurring.
