1957 Matchless

Whilst waiting for parts for Triumph Thunderbird I was fortunate enough to locate a 1957 matchless G11 which was part of a deceased estate and was only partly restored to good to miss.

I am endeavouring to achieve the result as shown in photo below

Decided to refurbish shock absorbers as sourced from USA existing ones purchased had no internal components

Commenced by dismantling and cleaning and polishing components.

It was necessary to replace rubber bushes sourced rubber and was able to get bushes cut utilising a very high pressure water cutter.

For assemble it was necessary to make a jig to allow compression of spring to facilitate assembly

Amazing one kick and bike was running a little bit of further tuning to far advanced

On to the next challenge a 1948 Velocette MAC a lot of pieces in poor condition with the need to source considerable parts

Will keep me from being bored I guess!!!

Below is photo of current collection at this stage undecided whether to keep all running out of space



Worth the effort

  1. Do you ever do engineering jobs for others?
    My father George Campbell and brother Keith sometimes need specialist work done for their Classic racing bikes?
    You would find their collection of bikes pretty interesting, despite the fact they are not immaculate restorations. Their goal is not the same as yours. Their goal is speed, but I think you would be impressed with what they have achieved.
