Hi guys this is my first time posting on here.i had a question i have tried everything to get my carbs on my suzuki gs1100ez right i can turn the screws rich as hell our lean and on deceleration it pops and cracks really bad plus at idle it surges from 1100 to 1500 and if i turn up the idle slightly it goes up to 2 to 3000 and surges from there.i jetted the Mains to 138's and pilots to dj160.i have a inline fuel filter on it but I'm not sure if you can have it on these bikes because they are gravity fed i have spent alot of money on this bike and everyone wants me to sell it.but i don't want to give up and feel defeated i need help i check everything for vacuum leaks and there is none cylinder 1 is giving me the most problems tho keeps fouling the plugs like its to rich but i have the idle screw leaned out.any feed back would be great.thanks
 
Welcome aboard Andrew

not enough information in your post to help you as yet

Have you been lurking? Read thru the Megawelcome? Checked out BassCliff's site?

Go to the GS Owners forum, check out the sticky thread, read a lot and tell us how many of the Top 10 Newbie mistakes you've made

There's no shame there, this site is crammed full of info (so much that some people complain about it) just waiting to help you out

Your running lean, hard to say why as yet. What's your intake and exhaust? Did you put a jet kit in it? Change the intake boots? New O rings? Clean the carbs? adjust the valves?
 
carb jetting

carb jetting

I have a new 4 into 1 Mac exhaust.new marxi racing air pods.i have a dynojet stage 3 jet kit in it.replaced all intake manifolds and clamps.what o rings are you talking about and i don't know how to adjust the valves. the carbs have been blown out with compressed air and carb cleaner.anything you can think of i pretty much replaced it.I'm just wondering if my inline fuel filter is not letting the carbs get enough gas cause are bikes are gravity fed.

You want to keep this bike? then you need to clean carbs properly or join a large mob at wit's end . go here

You've spent alot of money- checking valve clearances is a must and can be done cheaply and easily. Avoid it at your peril
 
Well, did you go over to the Megawelcome?

The Top 10 Newbie Mistakes?

You don't know how to do it?

It's all in there
 
Where is the mega welcome and top ten mistakes is it on this website cause i can't find it.
 
well, do those maintenance items, ditch the fuel filter and see what your results are

Nothing going on with your bike that hasn't happened to someone here before

You may find that the pods are a problem. Many members report that the cheap pods make the bike more difficult to tune. Do you still have the airbox? If you do, you might consider reinstalling it to confirm where your tuning problem are. If the bike runs well with the airbox, then you can switch back to the pods


Where'd that pod thread go that someone made up last year to illustrate his troubles?

OK, you got some work to do. Lots of tiny idle circuit passages in these carbs that get clogged and resist blowing out until crap is dissolved by stripping and dipping. If idle circuits ain't clear, you will fiddle with other stuff (idle mixture screws) to compensate, but this causes other problems like the stuff you described in start of this thread. Then add the pods to this and you got more fun. (Why #1 is running rich is another issue.) Best to clean carbs properly and then sort out the pods and dj stuff. You have to be methodical or you will get frustrated.
