Backfire

Dear Ralph:

My Indy Classic seems to have a problem with the throttle override kicking in at low rpms which causes the engine to backfire. Is there any way to unhook or disconnect this system ?

Neil:
Under no circumstances (other than in an emergency to make it home) should you render the throttle safety system inoperable. You should check the throttle cable tension and free play before messing with the safety system. If proper cable tension does not fix the problem, hold the throttle lever stationary and press the throttle. If the system is working properly the engine will die. Another possibility is the kill switch which can cause erratic low rpm running. The connector for both of these systems is under the handlebar pad (brown and black wires). If everything still works after you unplug this coupling, there definitely is a problem. If the problem is in fact the safety switch and not the cable (highly unlikely), replace it.
