Re: i think my "80cc" has issues. top speed only 28mph with shifter kit...
i am using the stock air filter. with the cover removed and the black filter thing bolted directly to the front of the carb for more clearnce, i just shortened the screws.
i tried many diffrent gaps .020"-.028" and nothing changed. what is directhits from pulstar? are you talking about ignition modules? i read your other post and i think i could possibly have a bad CDI is directhits an upgrade replacement or something to add in addition to the factory CDI?
