X4R Z155 popping on decel

Recommended Posts

I have a Pitster X4R with the z155 motor. It has started to pop on decel. The weather is getting warmer but I don't know if that should affect it. What should I do? The bike runs fine, just pops on decel.

That typically indicates a lean pilot circuit, but the warme weather should actually have it running richer. Regardless, try tweaking the air (or fuel screw, depends on what carb you have) screw one way or another and see it makes any difference.
