This guide details how to bypass the throttle stop governor on a Coleman CT100U mini bike to increase top speed. The process involves either bending or cutting a small portion of the throttle stop component to allow the carburetor to open fully, achieving a top speed in the low to mid 30s from a stock 19-20 mph. The video emphasizes that removing the return spring is unnecessary and can hinder proper operation.
This video provides a step-by-step guide on how to remove the throttle stop screw on Coleman mini bikes (BT200X, CT200U) and similar engines like the Predator 212. The modification aims to increase top speed by allowing the throttle to reach its full open position. The instructor demonstrates the process, including dealing with tack welds and reassembling the carburetor, while also discussing expected performance gains and potential pitfalls.
