Okay, I own an 07 GS, the weather recently made a rapid and drastic change, getting colder by about 40 degrees give or take. As this happened, the bike began to run like sh!t. The engine started making a random tick(It's not loud and It's not cyclic) and idle started having issues(drops slightly with tick it seems). Also, it likes to die at lights. I believe the majority of my issues are the fuel air mix. The bike preforms just fine once it's going, and doesn't have power loss(except for that tiny dead spot from jet kit, but unless your me you barely notice). My question is, do you agree or have another idea about it. Thanks all, and you are all ass savers for me :D
the tick with dropping idle is either pop-back or back-fire, both indicate lean jetting (its a gs500, lean as sin from factory). if it started doing it only when cold i would say your jet kit is still too lean. but it could also be vacuum leak. or clogged jet but less likely because its temp dependant. So check for vac leaks and if none then rejet again for the cold.
okay will do, and whats the easiest way to check for vacuum leaks?
first just look closely with good light for tears or holes in any vac line or the rubber boots that hold the carbs to the engine. if there are no visible tears then turn on the bike and let it idle and listen real close for a hissing sound. if none is heard or the bike is too loud to hear (like mine, thx V&H :cool: ) then you can, carefully, spray the lines and connections one at a time with carb cleaner or starter fluid (if your carefull ) with the engine running. when the engine idle jumps the part your spraying has a vac leak. common leaks are; the boots that hold the carbs to the engine, petcock and line, and the vac caps on top of the carbs. of course any thing can leak so be slow patient obsevant and safe.
P.S. whats your idle set at? it should be 1200 or so when fully warm and no choke
P.P.S. what jet kit you have? the dead spot you refer to sounds like leanness
idle is at 1200, and have dyno jet jet kit
dyno jet kit comes with many jets, easy to jet too lean, try testing for leaks then if none rejet BIGGER
forget it, I guess I never learned how to read... :D
Tick could be due to a sticky valve, that would also explain the other symptoms.
Assuming nothing has gone busted on yours (fuel line, vacuum line, exhaust gasket, air filter, gas tank or other electrical etc) ...
My first guess is - Its lean.
Solutiuon: Rejet, + 1 all around.
#2 This happened to my chopper of late and hence alerted me to the possiblity of weather affecting that, cos even here we suddenly had a cold snap after which it warmed back now ... but this hit me when cold.
The gas in the tank of the gas station gets more condensation from the colder weather. That especially is severe if their reservoir tank is low on gas and they dont see much turnover. The other thing is, gasoline vapors will occupy much of the tank's free volume obviously when its warmer in the warm months ...
Anyway a cold snap dumps water from condensation into the gas, and you could be the sucker than has ended up with much of that in your tank. I know I was, cos I filled up gas at this place after a warm day and suddenly after dark it got much much colder, and I was getting home and had to fill then.
I drained the tank and found it had water. I drained the carbs and got more water. I sprayed carb cleaner in the carb through the drain (a savage has a large drain bolt so you can get the jets that way if they're not crammed full of crapp) ... and when it was all dried out, I put fresh gas in. Gone problem solved.
So I guess look for water in gas and clear it out.
Cool.
Buddha.
okay, here's the thing, mechanic has jet kit somewhere and I doubt I'll be able to get it back( I got screwed by him very long story), I don't have the $$ to buy another jet kit, can I try to adjust the mix first to see if that helps with it, also will fill up with gas as soon as i burn it off(i have nowhere to dump it). Does anyone have the pages for how to adjust the fuel mix for an 07, I have the clymer, but the carbs aren't up to date. Thanks all
On both carbs:
Try going out 1/2 turn on # 27, mix adjust screw. (This is outside the float bowl, so you do not need to take off screws # 38.) You may have to remove a small metal cap, #42A, covering the adjust screw to do this. If so, search on remove idle screw cap. That will involve a drill, if you are up to it.
After this, ride and report.
Read this first for better pics:

Also, tuning a carb over the internet is impossible.
Have you seen this Mikuni carb article? Awesome writeup by some Yamaha guys.

Good luck.

And let me also say, thanks to TheGoodGuy for the great freaking pics on that writeup that I linked to above.
awesome thx so much, now can I use a phillips head screwdriver to turn that screw, or do I need to use something else?
I use a 6-sided screwdriver bit (3/16" flat) with a mark on one side. You can't get a long screwdriver in there.
okay so a flat, and I assumed that I couldn't get a normal screwdriver in there, I'll find one with a 90 degree bend or something, thanks
Good news! I got sick of waiting for my mechanically inclined friend to come over this week and adjusted the mix myself, I only did the right side carb because it sounded like the tick was on that side, opened screw half turn and presto, no more tick! Granted it is 60F today but I think it was running lean and I fixed it, I'll take it out tonight when it's colder and see if tick comes back but I think I did it :D btw she idles happier now too, and choke works better thanks all for all your help, and let me know if I am epically wrong plz
Dont just do 1 carb, do both, unless you know that its been screwed up on that 1 side, like someone drove the air mix screw deeper into the body than its originally intended. Unless that is the case, set them both equal.
Cool.
Buddha.
well I think it may have just been that carb that was off, because it really sounded like just that side, what would happen if I don't adjust the other one and I'm wrong?
If you're wrong ... maybe nothing ... or may detonate and eat a piston ... but that's usually at higher load and rpm ...
Do a plug pull @ idle ... if they both look the same just let it be then ...
Cool.
Buddha.
okay, just to be safe I opened up the other carb a little bit too, next time I have the tank off I'll look at plugs
you dont need the tank off only the side fairings. only takes 5 mins and could save your motor. i dont understand why people buy a bike that is as easy to work on as the gs then get lazy on doing the final check to make sure its set right. its not that hard.
well for me to take the fairings off would take awhile, and the thing is either blown or not at this point, it ran like that for a long while, it's got more fuel in the mix and has no tick or ping anymore. I'll pull the plugs when I do my chain adjust in a few days, and if it goes out before then it's screwed anyways :dunno_white:, and with how rich my garage smells after warming it up today, I'm pretty sure it's not lean. For us mechanically disinclined people, even simple tasks take forever man
ok but to check the plugs dont pull the tank. and your chain tension has nothing to do with the plugs either. just letting you know since your mechanically disinclined. If your so helpless then dont ask questions just goto a shop. i hate people that want to do something and want to know how then make F***ing excuses as to why they cant to it or they will do it when they do a different part. its 5 mintues to pull a side fairing for you me or the munkey down the road. theres 5 frikin allen screws and 3 push pins.

Its not my style to ever get in the mix of an online fued, as I have said before, its dumb as f*** to argue over online but Josh your are being an @$$hole. People like you just ridicule people like F.B. which keeps them from ever learning any mechanical skills. This forum is meant to help everyone, especially the ones who have no idea what they are doing. I am a mechanic by trade, I work on helicopters and I work on cars, but I have never had or worked on a bike until I got my GS. I used to be the biggest jackass here but I learned. I havent had to take my fairings off my bike but I bet if I did it would take longer than 5 min because its my first time doing it and thats because I have all the tools. Do you know if F.B. has metric allen wrenches? Or metric tools in general? if he doesnt thats automatically a 1 hr job just getting tools. If your going to post something then make sure its helpful or dont post at all.
F.B. if you decide to take your fairings off then get metric allen wrenches because if not then you will more than likely strip the bolts. Good luck buddy.
thanks joker, josh, I got the tools and I know my chain tension has nothing to do with engine, but that is the next thing i need to do so while I'm on my ass screwing with my wheel I might as well pull the fairings and check the plugs, but some of us have little things called lives that make it hard to work on our bikes every day. Someone tard farm my post before this gets ugly please
PS I'm mechanically disinclined, but no one is that stupid, that was just a low blow on your part to make yourself feel better because you were having a bad day
I just removed the fairings a couple weeks ago, I believe you need a 5mm or so. I think. Most of the work on those parts all have the same allen head. for the most part that is. And on mine, there were 4 screws that connected the side fairings to the front fairing that only fit right if put back in the place they came from. Took some trial and error for me first time because I hasted through this and didn't pay attention to the differences in the screws.
thanks for the heads up on the screw sizes, I'll remember that, and the size allen :thumb:
lol...lives. i am on the road at 6am and dont get home until 5-530 pm. theres the deal you asked for help then after people try to help you turn into the i cant do that right now. both you and joker need to do some looking around and look at how many times a sipmle question is asked and how many times that simple question is answered. I have never in my live seen the same things asked and answered so many times and then when someone pulls up an old post some jackass hits them for opening up a old thread., I would mush rather see someone do a search and then post in a thread like the 17 tooth sprocket one then to keep posting new threads about the same stuff. Like umm hysung 250gt tail on a gs.... if that person would have try to look before posting they would have seen it has been covered a few times. or how about and carb with hanging idle if they looked they would find that in the FAQ section theres a sticky that covers it in great detail. I am sorry for snapping at you but just pick a topic and search it and see just what i am talking about.

Not necessarily true. I searched for hours about modifying the rear half of a GS5 into a paddle wheel for a house boat and didn't find crap. I think it would work.
ok well that is just dumb. i thought that one was on here....but there is one for gs500 with a sidecar. and FB if you really wanna see what i mean stick around til next spring and watch.
I'd say I have to agree that reposting of a Q & A subject is slightly annoying but a couple of things need to be assumed:
Just because they are on this thread and a forum member it is not a for gone conclusion that they can properly use all of the capabilities of the Forum Software search engine. Those that come here for GS help probably don't care or want help on how to use the Forum web site, they just want to fix their bike as soon as possible with out damaging it. SO if you think in those terms;
"The only Stupid Question? Is one not asked!"
Also if you know the answer and where it was asked before simply posting the old thread for them will get them the answer faster then posting how annoyed you are at them for asking repeat questions.
Not looking to join an argument but the search function on this site is not always useful unless you have exactly the right keywords. Earlier today I was trying to find a post where a guy did a cool green paint job on his bike. I remember he used a piece of screen to add an effect that looked like snake scales to me, tinted the clear coat green, and had experience painting cabinets. I tried using all kinds of combinations of words like green, paint, tinted clear, screen... even cabinet and still couldn't find the post I was looking for.

i dont know maybe my search function works better then most others on the forum. that was searching under green paint on the first page of the for it brought up. :thumb:
Thanks Josh, that is the one I was looking for. I think part of the problem is that titles of threads are not always descriptive of the content. The one I wanted is titled "The transformation begins" not "My cool ass green scaley paint job" :laugh: I am guilty of that myself, my latest paint thread is called "killing time".
When I search "green paint" that "transformation" thread is the 8th result and only considered 28.3% relevant by the search engine. The first 4 results have something about paint in the titles. The 5th result which the search engine thinks is 33.8% relevant is titled "how often and with what do i lube chain? noob". Once seeing that I assume that my keywords were not working so I try some new ones. I guess it is lack of persistence on my part but I've been conditioned by google to look for my answer in the first few search results and consider anything past that to be unrelated crap ;)
