With most throttle assemblies, there is some room in the housing to increase the response. It varies with the manufacturer and the gains may be modest. Increasing control is almost always possible. It usually results in more rotation to full throttle.

Normally, your carb/throttle body, stock housing, cables and throttle tube are required for development. I can work without the carb/throttle body if you supply the measurements below. It's best if the carb/throttle body are included so that I can thoroughly test the action with new throttle.

Because I can not control the way you use the custom throttle, a waiver of liability is required. Please read the text below and make sure you can agree to it. I will send you a Word or text file for you to review and electronically sign prior to committing the work
