5hp Sting Ray
Here is some pictures of my new 5HP 49cc Schwinn Sting Ray. http://au.youtube.com/watch?v=UsVTfmiODAs 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.
