Hi. Back again after a couple years and buying a tw200 again. Couldn’t stay away I guess. Well I got around to taking the carb apart and the jets were pitted and nasty to a point where I couldn’t see what size the jets were. Can anyone tell me what the standard jet sizes are for this year’s carburetor? Also, is shimming the needle and larger mains also recommended? I’m running the same stock exhaust and air filter. Thanks!!
