1978 Tracker
XS650 Enthusiast
I just picked a clean tracker 1978 with a 1983 motor installed on the resto. I get a random misfire on the left cylinder like weak spark. It has a single coil, I thought 1983 had the dual coils. New bike to me and don't have the manuals to trouble shoot yet. It runs great but has a random miss fire on the left side. Any suggestions?
