Cant passs 20mph!I got a bike phone holder to check speed ..and it wont pass 20mph!thats when it starts to hold back I've road it across town about a 15min drive and 15 mins back..around the block, store..38 tooth sprocket,throttle low and mid fine but the full throttle is what's frustrating me..i kno she got more in her!...did 16:1 one time due to the second time it was going lean or something and the gas was sucked up quickly..then changed to 20:1mix..still on..since I've put jet #75 it finally idles better and bike barely gets hot as it used to.. Not sure if I should try jets 71-74..I took the plug out and took more pics from the run across town and around the block..and I weigh 220lb
