Here is some pictures of my new
5HP 49cc Schwinn Sting Ray.
Race Prepped pocket bike motor, running through the bikes gear system.
Makes it an 8 speed.
My top speed so far is 70.4km/h.
Has a custom tuned expansion chamber.
Hit powerband in 1st,2nd, and 3rd gears, then settles to sit on 50km/h cruise speed.
