Chris, they are gloss black from the factory and wet painted. Personally I wouldn't powder coat, it can chip off when the tyres are fitted.
agreed, a decent quality rattle can job would probably do the trick.
front brake discs are impossible to get now unless you buy worn OEM stuff. Fortunately companies like EBC do a decent replica (round disc with gold supports) and their quality is pretty comparable.
that front screen makes my teeth itch though.... please address it.
your rear fender is still stock which is really REALLY rare...... the last one I saw on ebay went for £350 so please don't mess with it. They all got hacksawed to bits in the 90's because people are idiots so now they're hens teeth.
Exhaust is a tad garish.... there's always OEM cans on ebay that just need a sanding and paint coat.
All in all though.... a stunning bike. Don't be afraid of sending it to honda to have a major service, its relatively inexpensive. Mine came back with the motor feeling so crisp and new. They also flagged up that a couple of parts were poor aftermarket additions (for example throttle cable) and replaced them accordingly.
Any questions please ask, like Ian said there's a more than a few carb fanatics on here.
