hey all, its been forever since ive visited this board. but in my experience this is the place to be for questoins. many knowledgalbe people here.  

i test rode a 96 gs last night. had a few issues, rusty chain, tire was kinda bald. but upon test riding it, my biggest concern was that from a dead stop, it was kinda sputtery until it hit about 5000 rpm. then it took off and ran like it should. i asked the guy about it, he said that to rectify that, he just ran the bike with the choke on partially.  

i am by no means a mechanic, but i do some wrenching. any ideas what the hesitatoin from? did he foul his spark plugs up by running it with the choke on? is the probelm deeper than that? carbs, jets? im just trying to get an idea of what it would take to get it running right.. i appreciate all info! thanks!

OK it can be like that till it fully warms up. Beyond that it should run acceptably well. Lean stock Jetting or crap in the gas or gas passages carbs clogged from sitting is my guess.
Cool.

jerky under 5krpm, but fine at higher....  sounds like a pilot jet issue?  I had a similar experience with one of my bikes.  turned out the pilot circuit was clogged courtesy of some crappy fuel.  Maybe cleaning out the carbs would help.

As for running with the choke on.. I have no idea.  but if that helped then is is almost certainly a lean condition with your pilots.  Maybe some of the mixture-setting gurus can chime in...

ha... one chimed in while I was typing... I love this board  :lol:    

I recently bought a GS with the same symptoms.  I replaced the pilot jets with #40s (Suzuki part #09492-40014) and shimmed my needles with #4 washers.  Problem gone, and warm-up time has reduced by at least two thirds.  Of course, while doing this work I cleaned up the carbs a bit which undoubtedly helped.

The jets are cheap, the work is a little involved (but doable) so you'd want to invest in a repair manual (available thru this site).  If you're going to have the carbs apart, you might want to replace the main jets with slightly larger ones (from 122 to 127.5--  sorry, I don't have a Suzuki part #).

The fact that the bike runs so crappy in its present state should help you lowball the guy and get away with it.  Good luck!

Yeah probably just lean down low, idle mix screws or pilots. Bikes with exhausts and pod filters are particularly sensitive to this when the air is cold.

Just rev her up and do race starts.
