Hello Keith, looked at this myself for my Z1A project and didnt fancy paying the £650 to have them done proffessionally so had a crack at it myself. I have access to a hot aquaeus cleaning bath and a bead blasting cabinet. But the rest is just bit of work and patients. some before and after photos on my DavesZ1A project on projects forum. I have had some more bits replated by Mikey since those pics were taken so they look even better now and they are now just about to go back on the bike. and will be posting more photos on the project soon.

Soak em in cellulose thiiners and then clean em with 00 gauge wire wool, fine scotchbrite pad and little brass dremel brushes for the fiddly bits.
Brought mine up good anyhow.
Don't get thinners on the non metal parts though!!
Cheers from Mark

A long time ago, someone recommended to dunk the carbs for a while in brake fluid. I have done it without much success. It's a messy job!
I put my reason for failure, because the modern say dot 5.1? (non silicon) is much milder than the old stuff. Meaning you can spill some on your tank and if you are quick you will save the paint. Whereas, the old stuff would ruin a tank quickly.

Hi

I bought an Ultrasound cleaner a few years ago, it was about £180.00 for a six litre tank (but you can get bigger - £££s).
I use it all the time, and the results are impressive. The 6 litre tank is not big enough to dunk a bank of 4 into, but i just turn them around.

A few tips;
You can get cleaning fluid to mix with the hot water, but be careful that it does not react with the ally, i had one carb go black. I use hot water and fairy liquid now.
Dismantling completely is best, but if not, try to remove all seals, as the best way to get all the crap out is by cooking as hot as possible. Mine goes up to 70 degrees, and blitz them for a few hours at least.

This kit does anything, caliper's, master cylinders, even the wife's jewellery. It's great watching all the crap just float away in the tank.

Thanks for the help.
I have sonic cleaned them now.They are clean but there seams to be some slight corrosion that wont come off?

[KwackerNut]

If the corrosion has tarnished the base metal, this discolouration will still be left behind, the ultrasound will only remove the oxidised crud.
I have read about soda and aqua blasting, and these may remove stubborn corrosion, but have not tried these techniques.
