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.

Quick Summary

To increase the top speed of your Coleman mini bike, remove the throttle stop screw. This screw limits the throttle from opening fully. By removing it, you allow the engine to reach its maximum RPM, potentially increasing top speed from around 19-20 mph to 25-26 mph. This modification is common on models like the BT200X and CT200U.

Frequently Asked Questions

How do I increase the top speed of my Coleman mini bike?

To increase the top speed of your Coleman mini bike, you can remove the throttle stop screw. This screw physically limits the throttle from opening fully. By removing it, you allow the engine to reach its maximum RPM, thus increasing the vehicle's top speed. This modification is common on models like the BT200X and CT200U.

What tools are needed to remove the throttle stop screw on a Coleman mini bike?

For removing the throttle stop screw on a Coleman mini bike, you'll typically need a 10mm socket or wrench to loosen carburetor bolts, a Dremel with a cutting wheel for dealing with tack welds or cutting the screw, and safety glasses. A torque wrench is recommended for reassembly.

Will removing the throttle stop screw make my mini bike faster?

Yes, removing the throttle stop screw will allow your mini bike to achieve a higher top speed. Stock bikes often top out around 19-20 mph. After this modification, you can expect to reach speeds closer to 25-26 mph, though this can vary based on rider weight and other factors.

What if the throttle stop screw is tack welded on my mini bike?

If your mini bike's throttle stop screw is tack welded, you have a couple of options. You can carefully cut the tack weld using a Dremel with a cutting wheel, or you can bend the throttle stop arm out of the way. The video demonstrates cutting the back side of the screw for a cleaner result.
