Dear Sunbeam Lovers,


 

Due to overheads,I reluctantly increased the price of the kits to £106 !          Sorry ! 

Todays Date :                              8th July 2025

New addition to for sale items:

Back by popular demand-  Dynamo pole piece screws
 
                                    Set of four £ 12 ( Post free UK )                        

 Extended oil pipe for those bikes with a sump extension.
 (
Reaches right to the bottom for the cooler oil. )

                       Stainless steel : £15 ( Post free UK )

New polished distributor cap shown below. I manufacture the distributor cap in batches of ten. Each one takes approximately one day of machining on a small  lathe, then milling operations and finally drilling and tapping. A two coat finish in satin black or natural finish satin aluminium of your choice.

Showing the distributor as it would be mounted on the engine, but now the contact breaker plate is reversed so points are at the top making adjustment and timing much easier. ( If oil seal fails on distributor shaft the points do not get covered in oil ). The distributor cap has a drain hole at bottom. Full written and pictorial  instructions are supplied with the kit.

Reversing the points plate is simply a matter of removing the two slotted head screws and rotating the plate 180 degrees.

The white wire is shown connected directly to the points underneath the plastic 'tophat'. The wire and support loop are supplied as part of the kit.
