Why Us?

We understand that fellow enthusiasts really want to restore their own motorcycle or car, but would like assistance with the tasks that can be time consuming, difficult or impossible without the right equipment.  

We specialise in the service and restoration of carburettors (see our carb page) to the highest standards but can also utilise the investments we made for this task to restore other components to look and function as new again using a range of techniques and equipment from shot blasting, vapour blasting, ultrasonic cleaning or zinc and nickel plating

Carburettor recovery and particularly motorcycle carbs can be a fiddle to recover. We will discuss with you what you're trying to achieve. Is it a daily drive/ride or a concours show vehicle. Understanding this enables us to give you a number of different options for a range of results.

We are based in the Bristol Road area of Gloucester near the quays, but can help wherever you are.
