Hey gang. Looking for some tech help and advice...I have a 1985 softail FXST which has developed a continuous mis-fire. Initially I suspected a partially clogged fuel filter, but it checks out fine. Any ideas, other than to take it to the local Harley garage ? It has a new motor, but all electronics are original...

Thanks,

check plugs and make sure battery conections are tight,could also be ignition module or coil going bad

 

Thanks RHillbilly. Gives me somewhere to start.
