70cc upgrade - jetting issue ?
I upgraded my scooter to 69cm^3 last night. I had to milled down the crank a bit to fit it: got an eton beamer and i bought a typical JOG cylinder upgrade.
But anywho, I kept everything else stock and this morning I cranked it up rode it around to break it in. Power and throttle improved but only does 30mph. Is it just the breaking in process thats limiting the speed ? or do I need jetting (increase fuel ?) My old 49cc cylinder can do 35mph. What do you guys think ? ![]() |
