Hey there,
Right, the bike in question is a zxr 400 h1

I'm getting everything from frame to levers powder coated tomorrow and need some advise.
Inside the clutch cover it two fine sets of needle roller bearings which are used for the clutch lever, if I were to powder coat this will the be okay as long as I re grease them after. Also the glass window for the oil level, will this survive too?
Am I better off leaving this?
Also the head race bearings, will these be okay or not?

The guy told me his oven is set to 200oC and the time is approx 25mins.

Secondally, what should I use to paint the engine?
I'm looking to go black and had been advised hammerite high temp, any suggestions?

Thanks in advanced!!

powder coating a bearing would be very stupid if you plan to continue using the bearing................and once you have powder coated your bearing grease will not fix it.
Removing powder coating from a needle roller bearing wont be easy

The bearings won't get coated, they will be masked off with heat resistent tape.
I mean will they survive the bake process

I left the roller needle bearings in my swingarm when it was power coated and they seemed ok after. I cover the holes with the heat res tape though but after the needles still moved so I don't see why they won't.

I won't advise putting any bearings with a rubber seal in the oven though

The grease will run out of the bearing and ruin the paint work and contaminate the oven. They will not do the job with bearing intact.

I'm not impressed with Hammerite's longevity. Is it a spray? Personally I think you get a better finish with a spray than with a brush-applied paint.

I've used Hy-Cote gloss black engine enamel with good results on calipers and would have no hesitation in using it on my engine. No priming required, gave an excellent finish. B&Q barbecue black paint has also been used by others on exhausts with excellent results.
