So I am re doing my gaskets on exhaust and doing the base gaskets as well. I plan to use a 25mm for the exhaust and for the base gasket I am not as sure. I have a stock engine so which gasket size would be best? .5mm or something as big as 1.25mm? Bigger or smaller? which one brings best performance, on the 50cc tomos a35?

Thank you

Re: Gaskets

The stock base gasket is a thin one. A thicker gasket would help open the ports up fully for better performance, but then you loose compression because the piston sits lower below the deck at TDC.

Re: Gaskets

If it didn't leak before stay with what you have , make sure it fits all the way around and the stud holes line up.
