Spent some time today under the fuel tank area cleaning and scrubbing. Can’t say it was the most exciting job in the world, but it needed to be done.
Once I’d removed the master cylinder and brake lines etc, I thoroughly degreased the entire inner front end with white spirit and a tooth brush until it was ‘clean’
I then took a soft brass miniature wire brush and set to work on the 53 years of hard dried mud, muck, grime and light surface corrosion. Good thing with the brass brush is that if you’re gentle, it doesn’t remove the good paint, but removes the flaky gunk.
Here are a few pics taken after it had been cleaned and brushed. Amazing how solid it is – nothing but light surface corrosion.






Here is an up close pic of the worst of it – nothing at all really!

Satisfied that the area was now clean, yet un-spoilt, I liberally coated everything in clear waxoyl. This initially has the effect of making the rust look worse than it is, but once dry, goes back to a pale patina colour.
I drenched it on with a 1” brush and will do this 3 times in total. This might not be the way some people might tackle it, but I want to retain it’s originality and ‘unpainted’ status. Nothing will be covered up, nothing hidden, just protected.



I removed the brake fluid reservoir and gave the area behind the spare wheel a clean wipe over. Again, lovely and solid.

The reservoir was perfect inside, so with a sympathetic wipe over on the outside, it is good for another 53 years service.

Here it is with a new rubber cap and connection hose.

Thankfully, the hard line from the reservoir to the master cylinder was in great condition, so I just cleaned this up with some wire wool.

The same cannot be said for the original brake switch. Not only is it very grotty, it doesn’t work following a bench test. It’ll go in the original parts museum anyway.

On a lighter note, thought I’d show a picture of the original tool kit and fuel level dip stick. Amazing to have this stuff.


And finally, here is a couple of close up shots of the TDE tail pipes. The quality and finish is second to none and I highly recommend them, despite their price.


Even the end that fits onto the exhaust box has a quality machined end.

That’s it for the moment. Next job is to finish cleaning the frame head which is equally solid, then I’ll give that a couple of coats of black ‘soft’ underseal – the stuff that doesn’t set.
After that, it’s in with the new master cylinder, solid lines, tank back in and finally I can get the engine running again.
