This item is purchased at the user's own risk
There is no warranty, implied or otherwise
Carb tuning is very critical and lean settings can cause a piston seizure
With a larger bore, the casting is thinner, resulting in poor heat transfer and slower heat dissipation
This can cause a piston seizure with even a slightly too lean of an air/fuel mixture
