I got my new Wezmoto clutch and OEM style brake lines in (custom length black, $155 the set including shipping) for my Monster 695 so while the bike's a bit taken apart, I'm planning to take a few more parts off it tomorrow and make them black by any means necessary 

1. Exhaust header (ceramic coat)
2. Exhaust brackets (two, powdercoat, about $20)
3. Headlight ring thingy (same)
4. Handlebars (powder for maybe $25, or should I anodize them for $55?)

Anything to look out for? Will powder or other coatings mean I can't get stuff back on? Do I need to tell the powder coating guy/gal anything special? What about ceramic coating and anodizing?

Well as it tuns out my local powder/ceramic coating guys calmed my fears by telling me they had some magic putty to put in the screw holes, and the ability to mask off other parts that I didn't want coated, so I think all will be well. Results in 10 days...

Why spend the cash on coating your stock bars when there's LSL carbon bars out there?

If you powdercoat the bar, very likely nothing will fit back on due to the thickness of the powdercoat.

IIRC, the OEM bar was steel, that can't be anodized.

Meh - it was $10 to powder coat and they masked off the parts where things need to go back on

 Pre-fit your exhaust pieces first if they are new so that you are not pounding on your newly coated parts. Make sure you wipe clean your newly coated exhaust header of oil/ greasey fingerprints before you first start up your bike or they will be baked in the coating.
