Wish there was the old Sportster.org list still around but as of now you people are the best source of ideas I know of. Don't expect a specific answer but just fishing for ideas.
Today decided to go for wife to a nearby Drive-in-Hamburger stand for lunch. Her on her Vespa and me on the 1992 Sportster/Sidecar outfit.
About two miles from home the Sportster bucked a couple times, at first thought was maybe low on fuel but then noticed the second it bucked the tach dropped to zero and just as fast it picked up running great. Turned around to go home and it did it a couple more times. One time while at a traffic light it just quit but a quick touch of the start button and it fired right up.
Other than the cutting out for a second it runs good and as smooth as any Sportster(1992) does. Kind of wish it would cut out and stay dead for enough time to do some basic checks. Right now about the only thing I can think of is to start it and just let it idle to see if I can have it happen while not riding. At least that way I might stand a chance of being able to see if say lights go out indicating a bad circuit breaker or key switch.
It is full electronic ignition so could be a bad pick-up or ignition module. But seem like they would be more likely to fail when hot and then take cooling down to start working again.
Anyone who may have ideas on how to check for a very intermittent and brief failure I would love to hear some ideas. If I could just get it to happen at a regular rate so I could know if I found the problem it would be great.
