1983 GS550ES Will not idle with hand off throttle.

[icebergal]

I just bought a 1983 Suzuki GS550ES, it wont idle with my hand off throttle. Idles fine with hand holding at 1200. Because of this (I assume) it doesnt like to start with electric start. If I get it bump started and start riding its fine until I have to stop, but then will not idle at all while stopped or clutched in with hand off throttle. If its likely just the throttle adjustment cable, can someone send a link or picture of a manual showing where the adjustment can be made?

Since this bike is new to you, there’s a bunch of stuff that needs checking. But let’s go to the idle stop screw...this holds the throttles open just enough to let you remove your grip. Look at center of this pic..there’s a knurled knob: this is the idle stop screw

Yep, that idle stop is the first place to look. That being said, your starting problem, with CV carbs., that you have, you should never open throttle "at all" to start the bike. When these carbs are flowing & adjusted correctly, giving any throttle will cause it to "not start". Probably a lot to learn about your new (to you) "83" bike, good luck & heck post some pics. just to prove to us you really own one. Good luck & welcome to the site.
