My bad on previous post. Choke has been checked and it does make a difference. It's just not a big one since it's running so rough already.

That was the next step. Electrical. Spark plug, plug cable, coil, stator, cdi.

Sounds like you might be on to something with the plug wire. Take the cap off and make sure you have a good connection. If you have the length you can cut them back and re-attach the cap. If you have a high resistance connection it's possible you're not firing good at certain rpms. Maybe that would explain all the spooge. I guess if you were burning tranny oil you'd know it by the smell.

I had a plug wire shot on a bike once and I recall the bike just breaking up when I started to get on the gas. Otherwise it idled fine, so a bit of a different scenario. There were only a few strands of wire left at the plug connection and I was able to cut it back to good wire and all was fine.
