Just got done with a build! Ive been crusing all over town and have received alot of compliments. 80cc on a 700c Thruster from Walmart. Got the kit off Ebay. A few things Ive noticed. I need disc brakes... My engine sounds like it knocks... Doesnt idle well...screw doesnt do much...Ive adjusted the carb severl times... Dont think I get 100 MPG... I can got 27 MPH... o and the fuel filter only has a little bit of gas in it all the time... 20:1 mix...can I go with 32:1??? anyone have any comments on those things that would be great!!! other than that I think it runs great!
