Re: P150 Exhaust port width increase. (Attn: Dan)

measure straight across the bore. so you get the 37mm edge to edge not around the bore ( use a calliper gague). if you can keep the top 50% of the port flat and then radius down to the outer edge and keep the outer edge of the port rounded (to help stop the rings snagging), you may find it better

i would be tempted to say thay you have a short circuit at some point after the stator as open circuit and poor conections would be unlikey to cause a coil to overheat.

concider replacing the wires from the stator when you replace the damaged coil.
