Where is vacume on 1984 550gs suzuki - 1984 Suzuki Gs 550 L

Request the information from Suzuki.

It sounds to me like there may be a clog of some kind at one end or other end of this vacuum hose. This is what you will have to check. GOOD LUCK FRIEND

U need to check vacum lines...u can spray water on them to find where air is leaking out most of the time.

w-d 40 ,sprayed around questionable vacume vacume lines will cause audible rpm increase in the area where a crack or hole exists.

Sounds to be a vacume problem. Look around for bad vacume lines ,Listen for a hissing sound, Good luck . Sure this is your problem.

There should only be one main fuel line, from the tap to the carby, the rest are just overflow, and vent hose. If you have a vacume operated fuel tap, then it will be a smaller hose, from the tap, to a vacume pick up point somewhere, mabey on the inlet manifold.

could be a fuel issue or vacum issue also. If the bike stays running with you giveing it gas, then it may be an idleing issue.I would test first to see if it stays running when giveing it gas, if so then adjust the idleing. If not then I would reccomend a good fuel system cleaning. If the problem still persist then I would start checking for a vacum issue.
