Default Re: very bad gas mileage.

Damn, i hope i don't need new engine bearings! I am 4 stroking a lot and the spark plug is completely black and covered with oil when i remove it, so i suppose i do need to make it a little leaner. My bike pedals quite easily with the clutch pulled in. My cruising speed is 15-17mph, i am keeping it a little slow for break in. some hills are around, but i help it up the hills with the pedals. Which way do i move the clip on the carb needle to get it leaner? Also, even if some engines are horrible with mileage are they as bad as 10-15mpg?
My motorized bicycle is cooler than your Vespa, even though you can go faster.
