So I bought a 100cc motor kit to upgrade my 80cc bike when the engine went out. My 80cc kit would hit 32mph easy. When I installed the new 100cc kit it would only get up to about 20mph. Not exactly what I'd call an upgrade lol. I checked and rechecked everything twice, fuel ratio, carb, spark plug, fuel flow, cable tensions, only thing I could think was maybe compression. After a while I was so frustrated I ordered another 80cc engine by it self. Installed that and it also only gets to about 20mph. I know these bikes should have a little more gitty up than this.
My oil ratio is 35:1, Ngk spark plug, spark plug wire from a car (bought at AutoZone), heads torqued to spec. Carb, float and bowl are clean.
I just can't figure out why my power has been so restricted on these last 2 engines. Any help or ideas would be greatly appreciated.
