Last update
Hello I'm Ron owner and operator of RB Designs and have been designing and developing, manufacturing, and serving the machine-shop high performance industry for the engine builder and motorcycle weekend warriors to the deticated compition racers for over 50 years now. So it is time to slow down and enjoy life and family and will not be working my business on a almost 24/7 bases anymore...

The time has come to reorganize the business we do and our businesses as a whole, as I have now turned 70 years old. I still love my work and want to continue doing the things I love, so we are changing the line of work we do. We will still continue to supply New Modified Carbs for certain models and do our great Head Mods for certain late model 2 Stroke singles.

We do want thank all of our wonderful customers over the years for giving us the opportuity to help with your 2 stroke performance needs. We hope to continue to supply you with our great modified NEW carbs and head mods along with our other custom M/C machine shop needs.

NOTE! It is best to contact us via email for complete pricing including shipping, shipping requirements, etc. before sending your payment and product to be modified. When sending an order make sure to include your type written;


... and another necessary information and instructions.
All prices are subject to change without notice.
