So I have used the search function on here but I wanted to list my specific problems to see if it is all stemming from 1 issue or multiple. I have a 2006 Suzuki GS500F. Here are some of the issues it is having:
- When starting with the choke on, the RPMs fly up to 4000 within about 2 seconds of being started.
- The bike will idle at around 1500 RPMs if it is cold (Hanging idle after it has warmed up) and it misfires quite a bit if its idling at 1500.
- If I do small quick pulls of the throttle the bike will miss.
- Once I start riding, the bike seems to run and ride fine until I pull up to a stop and hold the clutch in, it idles at 4000-4500 RPMS.
- Not sure if this is an issue but the bike pops and backfires quite a bit when downshifting.
The bike has a Jardine exhaust and I just had the carbs rebuilt from a shop but it did not seem to fix the issues. Any ideas?
Thanks
Welcome to GSTwins.
This may not fix your problem, but I have to ask when last did you replace the sparkplugs? My 2004 F ran unevenly until I decided to replace the non-stock plugs which came with the previously owned bike. After the plugs install, the running became a lot better.
I'll let the more experienced members assist you with the idling problem.
Yes spark plugs could be a reason. but otherwise you are running lean with possibly a vacuum leak.
Check for vacuum leak, if that checks out put in +1 all around = 132.5 mains and 20 pilots, put the washer from on top of the e clip in the needle to under the e clip and set air screws to 3 turns out. While you're in the carbs swap the phillips head float bowl screws for allen head and synch them by eyeball.
Cool.

just see the link in my signature. Buddha is probably right about the diagnosis but you need some background on how it's supposed to work.
