I've been messin with this bike off and on for 4 months now, playing with it trying to get it to run "RIGHT":banghead:. I bought a new (used) carb and cleaned all jets and passageways before installing.. Bike will NOT start without the HOTstart ON. Turn the choke on it dies, and if you keep the bike running(which is not idling) exhaust heats up REAL quick and glows...(too lean !) Stock exhaust, stock air filter, stock jets(I think... they look exactly like my other carbs jets) Mixture screw is out 4 full turns, The needle is on the bottom clip(max fuel), -How can it still be LEAN? SOMEONE HELP !
