My bike to me looks great, however she is a slug... Can't get her to go over 20, Tried all kinds of things, changed the carb to the new style speed carb, a little improvement top end, but have sacraficed torque. If I turn the fuel shut off valve off she goes up to 28 until the feul runs out, then turn the fuel valve on again and back to a slug... Maybe its a bad motor? She has 560 miles on her and runs great, as far as being reliable for these things. I guess she is what she is. Have a group ride coming up on the 20th, guess I'll take up the rear and cruise. Open for any suggestions.
