Background: Bike is a 75 goldwing that I’ve rebuilt over the last 2 years. No real modifications, other than Harley exhaust. Bike was basically down to engine and frame a few months ago. Carbs cleaned and rebuilt, belts changed, brakes rebuilt, tank cleaned, electrical all hooked back up, timing cleaned and reset (split timing method), valves done, etc. Everything that needed to be done to get a bike going after 10+ years sitting.
I got the bike started and tuned quite nicely. It fired right up with minimal choke, idles nicely and drives like a champ. It’s actually surprising how fast it is for an old bike. I thought the speedometer was off when I was doing 80mph. Didn’t feel like at all close to that. I later confirmed that I was indeed pretty accurate. Yikes! Good thing I didn’t get a ticket!!
Here’s the problem: I’ll be driving along (highway speed, or around town, doesn’t really matter) and I’ll lose all ignition. Lights are still on, kill switch in the run position, but no power or spark. Sometimes it’s a second or two, others, I need to pull over and try to restart it. Sometimes it restarts right away, other times it takes 10 seconds before it will fire up (and all other electrics are functional), sometimes I need to let it sit 30 sec or more.
Here’s what I’ve done so far:
- checked battery connections and all the connections for the electrics around the battery.
- checked the ground by the coils. It was in an obvious place, so cleaned and tightened.
- changed the regulator (took it from the parts bike I have.
- the kill switch was cleaned as part of my rebuild process, but hasn’t been checked since.
Intermittent problems are such a pain, and electrics are not my strong suit. I’m hoping someone has a direction or two for me to check. Thanks in advance guys!
Here’s what she looks like at the moment, in case anyone is wondering. Good ol naked Goldwing w flat bars and brat seat.
