Work undertaken within the last few weeks. Only just around to noting it down.
The air filters they were in great condition, but there was a fair bit of rust in places, especially around the intake tubes. I thought I’d give them a clean and scrub, to remove the rust and to clean up the paint job. There was even a fair bit of paint from when a previous spray job had been carried out.
Bring on the electric drill with rust/paint remover ‘attachment’. Ever one for the technical terminology, me. 
Thoroughly cleaned and soaked in soapy water with grease remover, the areas of rust and dodgy paint were removed back to bare metal.
These aren’t the finished photos, but they came up to a great shine. Next to do on these is to prime them, then get the Hammerite black onto them to bring them up again. If I do a pants job, then I can always buy two new cases for £14.00, but why spend money if you don’t have to, right?
Looking good… I’m probably going to get a set of K&Ns when I get to the stage of putting the engine back in. If these end up being non-repairable (although to be honest they look great) you can have my set. Oh and if you need to remove the engine gimme a shout and you can use my crane. Cheers.
