Re: 2nd attempt at saying hi...
My set up is from Stanton.....43 cc Mitsubishi with the same size roller. One difference maybe that I am running 29'er wheels with 2.2 smooth Marathon Plus tires....might be giving me a higher effective gear ratio.
I run 93 octane Citgo gas with 35 to 1 gas oil ratio (still breaking motor in) I kinda have the feeling it will hit 40 miles MPH. I am going to switch over to Opti-2 oil when I go through the gasoline I have mixed up.
To be honest-I didn't expect it to be quite as fast as it is-I would have been happy with 20mph tops. 50 year old bones don't heal nearly as fast as 20 year old bones:-)
