does anybody know the colour code or the paint name for the clutch cover , rocker cover and alternater cover for a 1992 nc29 ??

No idea, Ive just done mine metalic black, but if you wanted them to look original then i guess you could use any metalic grey or gun metal colour paint.

Check on the RAL color table. This is not Honda code, but these codes for powder coating

Thanks for the help guys much appreicated.

Although slightly darker, Ford Graphite Grey is a good alternative. I sprayed just the ends of the clutch cover with some and it looks fine and is hard to spot that it is darker, its only the normal stuff from Halfords but has not suffered any problems with heat or chipping over several months.

Thanks for that mate il give that ago .
