What should the jetting be on a 97 Summit with pipes and 42 or 44mm carbs?
Should I be changing it from trail/lake to mountain riding. Also, how sensitive is it? Can I leave the jetting at 290 & 300 for everywhere and at every temperature or should I be changing it? :huh:

just pipes and carbs what are you looking for does your engine bog at the bottom, lift your needles, up a couple on mains watch your plugs and piston domes. is winter there yet, how cold is it, should you wait for colder weather before fine tuning. temp. compensators( holtzman eng. )
