I was wondering if anyone has considered changing the head gasket to a thinner one and will it still have room for the pistion and valves not hitting each other.

If I remember right some of the tricks I did on my 1987 YSR-50 was to put a thinner head gasket on the YSR which raised the compression just a little bit to squeeze out a little more hp from the 50cc engine and there was a company that made these thin racing head gasket for the YSR and was wondering if the same principle can be applied to the GROM.

Cheap hp maybe:rolleyes:

It might work but the gains are usually negligible.

I don't think the valves will be hitting the pistons.

The stock gasket isn't really that thick to the point where the difference would be that drastic.

Its another one of those things where the labor is going to be worth more than the modification.

but hey I'd be up for it if I ever had to take apart the engine. But if you are going to take apart the engine you might as well swap the pistons :D maybe bore it out too!
