You will notice the ‘Red’ lettered titles below, click on these titles to see the information for your bike. This is designed for you, the customer, to help you track down your parts required.

The chains list is designed to help you, as well as me, to be able to order the correct chain for your bike.

The same ordering process goes for the Batteries, the Carburettor Parts, the Headlamp Rubber Mounts and the Spark Plugs.

I have also added a ‘blown up’ version of each Carburettor, this will help you to identify the part you are looking for, once you have that, the order number for the part is shown. Quote this number when making contact for a simple, easy transaction.

If you should have any questions with regards to any parts listed, or not listed, please contact him, either through a phone call, the 'contact us' page or my direct email: Whilst every effort is made to supply the correct quality part for your bike, mistakes do happen, so please make contact ASAP after the part has been delivered should it be wrong.

The information on this page is based on personal experiences, there to be used as a guide and to help to make restorations of your own motorcycle pleasurable. If you have any hints or tips, which you feel, will help other restorers with any problems, then please send them in and i will list them.
