I have a 1990 TW200. The carb has 2 markings on it. TK in a circle, and Japan. Does anyone know what size carbs are on these bikes? I have always supported my local dealers, but this dealer is way out of line price wise for the parts and has very limited knowledge of these models. I can buy 1.5 new Mikuni carbs for what this guy wants for needle and seat, main and low speed jets. His price was $210.00 beleive it or not.
