Hi, I also have a 1986 ts50xkg which I am doing up, the bike isn't dissimilar to yours but has white panels, blue frame and gold wheels. I have been hunting around for the paint codes of the frame and white for the fuel tank as I've chosen the questionable (expensive) route to have them professionally painted and although i haven't found much in what I'm looking for i did come across a handy website for parts including every bolt, nut and washer you could care to have; https://www.motorcyclespareparts.eu/en/suzuki-parts/1985-ts50-off-road . I have also come across an Ebay listing for "ts blue 'frame paint'", which might be what you are looking for; https://www.ebay.co.uk/itm/2-x-Suzuki-Rm-Ts-Blue-Motocross-Mx-Paint-Frame-Panels-Plastic-Rm125-Ts50-125-/272410721575 . If anybody happens to know or know of a way to find the paint codes i'm looking for that would be great. Thanks.
