I bought a very high mileage K75S with a leak at the bottom front left edge of the fuel tank. I've had many motorcycles over the last 45 years, several of which had leaks, but they were either steel or fiberglass and were repaired with limited success. I had a leak in the tank of a K1200RS but I opted to buy a new one at significant cost and I'm trying to avoid a major cost with this 20+ year old bike so am asking for advice. Is there a repair kit available besides the liner kits or is it best to have it welded? If welding is feasible and I do it, I suppose I'd have to treat the inside anyway. If I do that and/or buy a used one, has anyone had success buying matching paint (pearl white) to refinish the exterior of the tank. Any advice will be greatly appreciated.
