Cleaning up a filthy cylinder head

Morning,

Ive got a z1000 head I’m getting ready to fit to an engine. It’s black painted and very dirty, and needs to be bare ally and clean.

Trouble is that the engine it’s going on has nice clean cases, but they haven’t ever been blasted clean. When I rebuilt the bike last winter I deliberately didn’t have them blasted as they have a little bit of patina and i wanted a ‘nice old bike in good condition’ not a complete ‘as it left the factory’ restoration.

My concern is that if i get the head soda blasted to get the paint and filth off it’ll come back looking like new and stand out like a sore thing when I bolt it on.

And thoughts or advice please?

Thanks,

Olly

Maybe speak to a few blasters Olly, Maybe blasting with some type of plastic media would just take the paint off?

Other than that paint stripper, gunk, elbow grease and patience :wink:

Try a paint remover on a small section to see whats underneath. I doubt it'll come up like that 'Just Blasted' look from this alone, in my experience a Stripper tends to leave the alloy grey anyway.

when ever I put any thing alloy in my ultra cleaner it comes out dull not sure if this is the heat of the water,
cant see just bubbles would do that.

my thought is dunk it in hot water for a bit or big ultra sonic bath, if it come back looking to new from blasting

problem and solution :D

I do vapour blasting and ultrasonic cleaning . Have done a few heads that were black but they were as new when done . There are a few ways of dulling them back but they are still very clean . Obviously there are various ways of paint removal that can't be bought from the local diy
