I've recently purchased a 1999 GS500E. The bike had just under 6k mileage. The bike when it revs up seems to slowly rev down. This is the most notable if you're sticking 5-8k RPMs for a period of time (2-3 minutes). After getting and maintain this RPM for a period of time, when i pull in the clutch & release the throttle, it takes about 15 seconds to get back to 1200 RPMs from being at 6k.
Ideas on what I should be looking at? (should I be thinking a carb issue? A spring need to be replace? etc)
Any ideas would be appreciated.
Welcome. That kind sounds like idle hovering... I don't really know much about it, but a quick search for "idle hovering" should tell you what you need to know...

Welcome! :cheers:
The problem you have described is very common to the GS - it is called "hanging idle" or "idle hovering".
Have a look at this FAQ thread for some ideas:

Searching for "hanging idle" or "idle hovering" will also turn up many related threads.
Good luck! Let us know how it turns out.
Awesome. Thanks for the amazingly quick responses!!!!
I just shimmed my carb needles and had a slight idle hover. A small twist of the idle screw solved it. The added shims had me idling too high.
