XS650 Enthusiast
Hello Group,
Picked up a 1980 XS650SG with 5100 miles from the original owner that had it in storage for 31 years. New tank, new fuel system and carbs have been cleaned and rebuilt recently with stock internals. No upgrades just bone stock carbs. New battery, replaced round fuses with contemporary plug in fuses. Bike finally runs on the choke but runs like crap. Rough on idle, when I tap the throttle bike dies. When I take off the choke bike dies. If I leave the choke on and let the bike get warm it runs for a bit and then slowly dies. When trying to ride it hesitates and then jumps to life and then hesitates, sounds like left side backfires. Sounds like its not getting The proper spark. And the plugs look completely different for each cylinder. The left spark plug is fouled, has a black film on it and smells of un burnt fuel. The right one is fairly clean and electrode on end is white in color. Where in the world do I start on this project. I'm not mechanically brilliant I'm just stubborn, won't quit, understand most shop manuals and some combustion basics with cars. I mainly bought the bike because of what is was being from the original owner, garaged for 30+ years and I wanted a winter project. PLEASE HELP and thanks in advance.
