Hello, I have a 1982 450 nighthawk that i have owned for 2 years but it has always missfired around 5000 rpm.I have fitted new jets and needles,plugs,coils etc. Also had the generator rewound and pulse tested and still have the same problems. any ideas.?
It sounds immediately to me like a stator or coil issue. It sounds like you’ve looked at both of those – but have you tested the coil with a proper ohm test? And have you tested the stator output at both cold and hot temperatures? How do your pickups look?
