intermittant power loss

Postby Bartmead » Tue Oct 16, 2012 6:15 pm



I was riding home from work today 70+-mph and the engine started to lose power. I could hold speed but it sounded and felt like a lost one or more cylinders. Then all of a sudden it smoothed out and I took off again like nothing happened. This happened 3 times before I got home(about 35miles). Sounds electrical right? Any Ideas where to start?

Is it points or electronic ignition. I had issues getting good clean power to my 1984 Dyna III and getting off the blinker power feed and to a solid 12V source (a relay) helped but in the end one of the pickup coils was failing and a new Dyna S was needed. But now she is solid again. I would sometimes have an issue where she would start on 4 cylinders, immediately drop to two (need to coax out an idle with full choke) then about 8-12 miles out finely hit on all 4 for the remaining trip. Confirmed as electronic parts too old.

Also, check the main ground cable where it bolts to the frame.

my first thought was fuel filter plugging up.
It is easy to check

My bike is a points ignition. I'm not sure if this was the only issue but it seemed to be. I was going to check my grounds and found that the positive battery terminal was loose. I checked the grounds and they were tight. It hasn't messed up since so that must have been it. Thanks for the input.
