They do run so similar. It’s honestly hard to say which one might be better.

When I start them with choke, the idle is even higher.

Off idle both bikes run great and have the same amount of smooth power. Now that you are suggesting a rich condition, I guess they would be a bit “stinky” for the rider who is second in line. I had originally just chocked that up to riding behind a 15 year old carbureted twin.

I pulled the air filter from the 06 and washed it tonight. I rechecked the idle mixture screws by lightly bottoming them out, and then backing them off 2.5 turns. Tomorrow I’ll go for a ride without the filter and see if there is any improvement. If so that does prove the suspicion of a rich condition; if so what would be the next course or action? Disassemble and inspection?

I think I’m going to work on one at a time, if there is improvement on the first one at least I’ll have a baseline to work with.

Thank you so so much for your help. I really appreciate it.
