A: The Moose CP Piston Kit does not require head modifications to be used. You may need to run a mixture of race gas to keep detonation out of the motor.

Can I only run 93 without harming the piston?

A: Yes you can, just make sure it is a quality 93. It would be better to use a higher octane or 50/50 mix of race and pump gas. But CP says it will work with good quality 93.
Q: Do you need to run race fuel with this pistion? do you recomend a jet size for a honda 450 with all the bolt ons & stage2 hotcams.

A: typically any piston that is higher than 12.5:1 compression should use a 50/50 blend or straight race fuel. Race fuel will help keep the detonation temp lower than where pump fuel burns at.
