Ok let's try and get the discussion of diagnostics off the classifieds thread.

If it's just idling fast, honestly if it were me I'd just ride it. I'm not seeing this as a big problem, or what am I missing? I have a 21119-1233 igniter box, but the cover is pulled off meaning at some point I suspected it didn't work. You're more than welcome to it, but I have my doubts that it will help. All the igniter does is throw a "switch" to fire the coils; it should just either work or not work.

I had to use the wrong one on mine, just re-pinned the connector on the harness and made a couple of jumpers. There's half a dozen different ignition module part numbers for various pre-gen model years.

I though you said in the other thread that you had corrected the problem? You couldn't get it to idle down? Could you re-state what exactly is wrong at the moment? I had a 5,000+ RPM idle on my gs450 (also a twin with CV carbs), and it turned out at some point I had knocked the butterflies out of sync. 15 minute bench sync and it purred like a kitten, after chasing the problem around for 2 months.

I am trying to get the bike to run below 3k and/or idle. Still have not fixed the problem.

Two different sets of carbs and still have the same problem.
