Question
Hi Bill,  I have a 1985 VT700 Honda shadow, runs great for a few miles then I lose the back cylinder and the tachometer at the same time sometimes it will kick back on then sometimes it won't. I have a 1986 parts bike and I have changed CDI boxes, coils, and the tach and it still kicks off. I can still get home on one cylinder. The next day it will start out great then here we go again. Going nuts I need back into the wind please help I'm out of things to try. Thank you Delmar

Answer
Delmar, Sounds like a heat-related failure. Do check all of your electrical connectors for the ignition and charging system. Sounds like you replaced all the external components, so time to buy a flywheel puller, gasket and change out the pulse generator coils.
