Engine Covers paint Colour

My engine cases (clutch and genny) could do with a spruce up. Does anybody know where i could get some paint for them either a similar colour from halfords or a yammy original??

Thanks in advance

There are some places that will mix you the paint you want, even if you just want a time & you can get the paint code off the internet I had it put cannot remember it now

Bung in your bike details and it'll give you the paint codes.
(Chances are the Yamaha paint code for the frame is 0035 Silver)

-edit- Looking on some UK sites they list the code as Yamaha 35 "Light Grey" or "Light Greyish Metallic".
You could take a chance on this: http://yambits.co.uk/silver-engine-paint-p-4093.html?osCsid=nvd1roo9s01kqtcfv8ovjlbpi6

When I resprayed my swingarm a couple of years ago BMW Titan Silver was a good match (I just happened to have an old Beemer of that colour at the time). Halfords do a three-part touch-up pack with undercoat, topcoat and lacquer - or buy individual sprays if you need to cover a big area.
