my motor ran great when I first got it, it probably has a couple hundred miles on it, it doesn't run so well any more, I changed the plug and I drilled out a bigger hole in the intake to lean it, it just doesn't run to well any more. also when the motor does start to wrap out (higher rpms) it seems to have high vibration, not smooth running, any ideas? its the 80cc. I'm thinking about stepping down to the 49 or 66 cc so I can go faster, I want to buy the best motor on the market, I saw the angle plug motors, any suggestions on what and where I can buy a new motor? and what mods are the best, carb, pipe, etc...
