Had that problem on my last bike, but have also seen it on others. It sounds like you have a leaky needle valve in your #4 carb. It could just be a little peice of dirt or an o-ring at the float needle base. It just pulls up and is easy to change. That cylinder is running too rich, fuel is getting by somewhere in that carb and fouling out your plug. Hope that helps. Bruiser |
