Race gas will lead you astray. It burns slow and changes plug color. Leave it alone. 93 octane is pretty high for an old design motor too. Remember that lower octane fuel makes slightly more power.
I'd try it with 89 unless someone chimes in with a better suggestion based on recent road experience with modern gas.
Ethanol essentially leans out the mixture slightly compared to conventional gas and has a lower energy density than straight gas so you lose a little power with E10 as a rule.

Thanks for the input teazer. I'll adhere to all that you posted. I am now running the 93 octane and it does seem to start/run better. I got two new carb rebuild kits that I will be installing tomorrow. I'll keep everyone posted on results. It's turning to winter here in wisconsin, so my days for riding are becoming very numbered.
Hi folks;
Well, I finally got my carbs rebuilt, and in the process, i realized that the floats were set WAY too high. They were at 28mm. Which raised this question in my mind. Being that the front forks are extended, did the person change the levels to compensate for the change in the angle that the carbs sit? Being that the carbs are at less of an angle than with stock forks, would 1 increase or decrease the float levels? Or does it matter? I left them as is for the time being to see how it ran. Still getting better than when I first got it running, and doesn't smell as rich. I'm thinking I should go back to the 22.5 mm factory setting. The change in carb angle because of the forks shouldn't make a difference.
