If I recall correctly, Jason at Swedetech has always told me to use VP ms-98 and never run pump gas of any kind, racing or not, AND to always mix the fuel at 6 ozs to 1 gal.
I found that gearing plays a big part in how the Honda performs. You want to keep it on the pipe as much as you can and if you lug it a lot, it will give you a rich condition. I think I’m jetteat with a 76 main jet now with clip in the middle. Have to check my notes for the pilot. I’m in central Fl.
