Yamaha YFZ 450 dies at idle

Recommended Posts

I have a 2006 yfz 450 that makes no spark at idle but makes spark when I crack the throttle a hair. Any suggestion on what could be the problem? I think it is either the throttle positioning sensor on the carb or switch in the throttle housing on the handlebars? Any suggestion would be helpfull.

You have two connectors on the carb, one is a three prong connector and the other is a two prong connector. Cut the wires one the two prong connector and tie them together.
