Parts list for vapor honing

(1/3) > >>

Hey all

Currently collecting parts for vapor honing, and want to get all of it done in one go, so making a list of all the stuff that needs to be vapor honed. If anyone can see anything missing, could they please chime in? I will update the list then, and maybe it can be of use to somebody else in the future as well :)

Everything engine
Crank cases + oil caps and plugs for crank cases
Bolts for crank cases
Bolts + spacers for engine to frame
Oil pan
Oil filter
Left crank case cover (polished afterwards)
Right crank case cover + oil cap (polished afterwards)
Alternator cover (polished afterwards)
Cylinder
Cylinder head
Manifolds
Cylinder head cover
Cylinder head side covers
Caps for tappet holes
Breather cover
Carburator bodies + top set and float bowls
Exhaust collars
Exhaust pipe joints
Pistons (for carbon clean up)
Valves (for carbon clean up)

Everything else
Front forks (polished afterwards)
Front and rear hubs (polished afterwards)
Front brake holder (polished afterwards)
Front brake bolts

Now, I left off anything chromed (top and bottom of carbs, fenders, exhaust etc.) and anything that should be sandblasted (frame, swingarm, lower and upper triple tree and other smaller steel items), so keeping this to items that should be vapor honed, but would like to make that list rather complete.

I have added comments on the parts that I usually see polished. Please let me know if they are incorrect. I have also added valves and pistons for carbon clean up, as I read somewhere that is a good method. If not, let me know, and I will take them off the list.

Any adds?

Oddjob:
The clutch, brake and kickstarter pedals are all chromed as standard, yet you said you weren't doing anything chromed?
Points cover is also chromed.

Top and bottom of carbs are not chromed as standard.

Don't do the oil pump, you can't see it when fitted so why take the risk of anything getting left in there.

They'll be some who say don't do the cylinder head or the carbs, I've bead blasted both of these on numerous occasions and never had a problem. So long as you clean them well beforehand and afterwards they are ok. However it's your choice.

Bead blasted hundreds of pistons, they do come up great.

I'd add the exhaust collets to the list.

Ah, just saw someone had done them, and my own is so dirty that no chrome showed up :( I have updated the list, removed the pedals and points cover and added the complete carburettor and both exhaust collar and pipe joints (not sure of these are chromed as standard?). Also removed the oil pump.

Is the top and float bowl of a carb painted same color as engine then?

Laverda Dave:
The carbs are not painted at all but left as natural casting.
Whoever you choose to undertake the vapour blasting make sure they are used to blasting motorcycle engines, they use purpose made bungs to seal any oilways, and they pressure clean the castings afterwards. When you get the parts home make sure you clean them and clean them and clean them again paying particular attention to the oil galleries. I use hot soapy water followed by an air line.

Oddjob:
Top and bottom of the carbs are done the same colour as the casings, lacquered alloy.
