1996 GS500 Problem

[cyberdork]

Starting tomorrow around 5 I am a born again GS owner. I'm picking up a 96 GS500 with under 3000 miles for 500 bucks! Thank you boss! The reason why she's selling it cheap is because when you lay on the throttle it takes a good 2-3 seconds for the engine to final rev up (not slow acceleration, just extreme delay). She took it to a local mechanic and he tried some things such as cleaning the carbs and replacing fuel lines (I'll get the complete list tomorrow). Does anyone have any suggestions? She said the valve clearances haven't been checked that she knows of. Could this be a possibility? I'm lost on what the delay could be. Thanks.

could be the slides coming up too quickly, or not quickly enough

buddha is our resident carb guru, he should be here shortly

Could this be something non-fuel related such as a bad ground causing low ignition power?

Jeremy_Nash is on the right track, and thanks for the compliment.

If you open fast and you have a problem (usually it falls on its face with a gasping sound, but this seems to be opposite) but it behaves when you open slowly = slides comming up too fast or too slow.

Only way slides come up slow is if the 2 holes in the bottom have been mostly plugged ... 1 is closed and other is reduced - like with the DJ kit.

Solution - replace the slides ... I sell a lot of slides, I have to make sure I have em, and I'll sell you slides for 10 a piece, a rejet with mikuni parts may solve other crap due  to DJ sheite, but I can tune a DJ as well ... either way, PM/post here and we'll see what we should do.
Cool.

As far as I know it has stock exhaust and stock intake assembly. The previous owner never rejetted it, so from what I know the stock carb internals are still there. I'm new to these carbs and aren't sure what slides are. Can you point me in the direction of a manual for the carbs?

You explained what to do if the slides come up too slow, but what about them coming up too fast?

[The Buddha]

If it comes up too fast - the symptom is, it will gasp and sound dry as you accelerate, and you cure that by closing off 1 of the holes on the bottom of the slide, or by training your right hand to open it at the right speed.
I am really not in favor of plugging holes in the slide, but if you must, buy a 4-40 tap, thread it - no need to drill, 4-40 is a good fit for the stock hole, and put in a nylon screw and cut it flush and sand it smooth.
Anyway, I'd only open the throttle as fast as it can accept it.
Cool.
