Hey guys Iv done a few mods so far to my 66cc, 29in cruiser motor bike, intake and expansion chamber exhaust,41 tooth sprocket and it goes pretty good around 30mph. I'm a bigger guy round 220 pounds and still want some more power without putting a bigger sprocket and losing top end speed.
I have heard are compression is around 6 to 1. Is that true? I want to go to around 9 or 10 to 1 ratio for more power. I have a lathe and am going to shave Down the head. I have researched but have not found any definite answers on how much I should shave down?? Also what head gasket to use or no head gasket?
Any info from anyone use had shaved there own head and successfully raised compression will be appreciated! And any tips!!! Thank you...
