AFTER BEADBLASTING ENGINE, what do you use to keep it clean , lacquer etc. what do manufacteurers use at point of assembly. im going to rebuild a z1000 a2 thanx

Hello Blackdog, best to avoid bead blasting, not only does it compromise engine reliabilty due to bead becoming dislodged later on but the rough finish will trap dirt and grime on the outside, there are a number of other finishes which are safer and smoother and so easier to maintain the clean apperance

Debben


For example......?

What do you recommend?

I`ve just had my carb bodies done by Doug Cox in Reading.

Very nice finish !

You will struggle to keep it clean as Debben says and just make sure you have cleaned the inside out to within an inch of its life to get rid of any remaning grit. Many on here are happy with bead blasting but its a touchy subject and has been the subject of much debate. I would never have any of my engines bead blasted but others swear by it.

Blackdog,
Vapour blasting will probably give you the best results, it's a bit like bead blasting, but done with a water solution, containing glass bead. R D Cox, are one of the best! Just make sure you clean out all the oilways thouroughly!

If you have already had your cases bead-blasted and you want the best finish, then I would have them vapour/ water-blasted.
The vapour-blasting works well on a bead blasted surface as it tends to microscopically seal/ burnish the small grain effect of the bead blasting.

I have been unable to establish if vapour blasting uses any type of abrasive. Maybe, some vapour-blasters have their secrets! The finish is superb and in my opinion, the ultimate, however, it can stain. Any of these stains can easily be removed with "Shellite". The finish looks as so it just came from the foundry.
