Hello everyone,
I’ve bought an ‘81 suzuki GS 500, and she has this problem:
at around 5500 rpm has an hole, the engine stutters for a moment and then gets over and continue to rev up till red zone high rpm no problems.
She has this problem at every gas opening,
I’ve tried almost everything on the carbs, I’ve mounted on a 4 to 1 exhaust and separate air filters.
jets mikuni bs carbs
47,5 pilot jet
130 main
needle 2 position (tried almost on every position this seems the best)
120 air jet
1 rotation fuel screw
fuel level ok,
synchro ok.
the bike idles fine, and below this point and above it’s pretty good
chain distribution it’s as manual,
spark plug correct
8 bar on every cylinder
thanks,
bye
