Hi. Many moons ago, I replaced the plastic choke cable holder on the carbs with metal versions, as the plastic ones tend to break easily, leaving the thread still in the carb. I seem to recall it was a yamaha part, but can't remember which now. Anyone know the part I need ? It's actually for a GSXR250 GJ72A, but uses the same part number. The GSX250F Across uses what could be a metal version (going by some footage I've seen), but that may have been modified. Any help appreciated.
