Ok so I recently bought a 2005 gs500 and I like the bike and everything but I have some problems. The bike bogs down in first gear at take off. After about 3k rpm, it runs fine. So I changed oil an plugs and cleaned carb TWICE. Bike runs now but the bog in first is even more pronounced. It's undriveable now. Also it may be Important to note that it cuts off at stoplights and stop signs unless I rev it while I wait.
The air filter is dirty. There's a new one on order. My questions is if the air filter could cause all this? Or is there just an awful block in the pilot jets? One thing I didn't think of when cleaning the carb is adjusting the pilot jets. I just put them back in at where they were before. Should I adjust them precisely? I read somewhere that u screw them in until it stops turning and then back it out 3 turns. Could poorly adjusted pilots cause the stumble in first?

Please help

I am not a carb tuning expert, but here are some things i have learned. The adjustment you are referring to is an air fuel mixture screw that is on the outside, bottom of your carb. It is not made by adjusting the jet its self. Does this happen after the bike is warm and the choke is off? You may just need to adjust your idle speed to start with. Are the carb jets stock? Is your exhaust stock? Is the air filter OEM?

Jets are always screwed all the way in.  The external mixture screw is the one that you are speaking of to adjust.

This occurs after bike warms. It's fine to ride with the choke halfway on but when my bike warms up it will die if I don't take the choke off. And that's when it messes up on me. I take off in first and it bogs down and dies. Like its getting no fuel or something. I assume the jets are stock and the air filter is certainly stock but I'm putting a k&n in soon.

Like I said, I thinks it's a clogged pilot jet but I can't be sure. Idk a whole lot about bikes or even carbs. A local shop said they would clean my carbs for 45$. I might just take them up. But I'm also thinking of maybe adding a dynojet stage 1 jet system just in case one of the old jets are bad.

Okay, here is where I would start. I think your engine is actually getting too much fuel, not starving. Once your bike is warm, there should be no need for the choke. Firstly make sure the fuel is new. Warm up the bike with the choke on. When  warm, find the idle speed adjuster on the bottom of the carb, and turn it slowly until your bike begins to idle higher. Back off the choke and adjust until you can turn the choke off, and maintain a 1200-1500 rpm idle. Then ride the bike a bit and readjust if necisary.
I have no interest in aftermarket filters or exhausts, but keep in mind that adding these things will effect and require new carb tuning. I would make it run right first before making adjustments that may throw you further off track, but then again Im an old guy and don't see the need for such things.

Does the bike run okay with the choke on? If it runs and rides fine you have an air leak. Possibly to do with the manifold etc.

Yeah it rode fine with the choke on but without it it has that bog in first. I was told today that it sounds like I'm running too rich so I may adjust the air fuel mixture screw. Where is that located?

Your bike is stock from the factoy. Do you think the sold the bike with screwed up settings in the carb? My bike was made in 19fricking89 and runs like a top. The carb is the most intracate balacing act on your dam bike and everyone wants to jump in and start screwing around with it. Why is it we see so many posts about this I have no idea. Use the search function as about 80% of the posts on the forum are about people screwinfg up the carbs and eventually fixing it. Get a servive manual, and look at how to do it right if you want to fix it yourself or pay for it to be fixed. I still think you just need to adjust your idle speed but do what you want, its not my bike.

There's no reason to be an @$$hole bro. If you don't have a useful contribution then just shut up. Take your rants somewhere else.

Let's recap. My bike is 2005 and I just bought it a week ago. I assume that everyone else assumes that I did not buy this bike brand new. It has had two previous owners. Let's also assume that they could have done anything to the bike. All I did was clean the carbs and the problem I was chasing is still there.

I do not want to "mess with the bike". I just want it to run, which it does not currently do. Any USEFUL information would be greatly appreciated.

I've gotten so many different answers. I'll be checking a few things once I get home from vacation. If that doesn't work, I'll be dropping it off at a shop. One way or another, I'll be riding this bike.

If your bike is runnin better with the choke on i believe that would mean that you re running lean. The choke, chokes off the air so that you get more fuel.

Make sure you aur mixture screws are atleast 3 turns out

Wow, didn't realize you were so sensitive mr camaro, let me offer a tissue. I will not stoop to name calling and whining and suggest you read my posts again carefully. I offered many reasonnable suggestions and merly stated my opinion. Most noobs looking for advice are not so rude as you but I apologize if i hurt your feelings. Most posts here are read with a bit of implied sarcasim. Agian I am sorry you feel hurt.

First off...you're last post did come across as a bit condiscending.  Secondly, you have 29 posts...tell me more about the noobs. 

Lastly, I agree with the aforementioned in this order:  1.  Check your idle adjustment screw...make sure the idle is up around 1250 with the choke off.  2.  If your bike idles fine, but still bogs in first, you can check the air/fuel mix screws (two of them)...turn them all the way in, then back it out 2 1/2 to 3 turns.  3. If this doesn't work and if your bike idles fine, my guess, based on the year of your bike, would be possible clogged mid jets.  These jets feed your bike after you crack open the throttle from idle before the mains kick in.

Try these steps in that order, then get back with us.

Thanks a lot guys. Thats what all the more qualified people I have talked to have said. So I'm goin to follow those steps in order. I won't be home from vacation until next week so I won't be able to tell you if it works until then.

I ordered new jets today to compensate for the new k&n air filter that's waiting for me (couldnt find a stock air filter ANYWHERE so I got the k&n at advanced) and I followed the reccomendations for jet size as per the wiki page.

Hopefully I will fix this thing when I get home. Can't wait to ride again. I love it already haha. Thanks for all the help though guys. I don't know anything about bikes but I've learned a lot here already. Most of my knowledge is cars though. I drive a 2010 Camaro SS, hence the name. Again, thanks for all the help guys, even the not so welcoming posts . I'll post and update when I get home. Later.
