Couldn't help but to add but I raced a 4 mill drag ported bike by k&t with shearers with my 4 mill hjr dune ported bike with t5s and left it with no problem. Thanks Kevin
Either one could but not 100% sure. Find another banshee and switch them to see if you get spark. 96 and above have different cdi's. If you have a Ricky Stator it can also be bad they're shit.
