Heres the run down.. my friend has a 1999 GSXR 600 that he couldn't get started (aka, just continously trying to crank the thing) and asked me to help.

So I siphoned the gas (been sitting since august) swapped the plugs, gave the carb a bit of a cleaning. Gave it a bit of juice directly to the carb and it would fire, rev up to 5k and then drop right back down and stall - however, this would only happen if we would give it a squirt of gas directly in the carb.

So after becoming a bit frustrated he mentions to me he had been messing with the idle screw last year and basically just turned it randomly. So, knowing it was already messed up I started playing with that and finally got the bike to idle - however, whenever it comes off choke fully it dies almost immediately. I played with the idle for a while and couldn't get it to a spot where it would stay running unless the choke was on atleast a little. Even if I rev it up a bit and then take the choke off I can't keep it alive.

I really don't know much about carbs or this setup - anybody have some ideas - I've explored and just about my reach of what to do next? Half of me thinks the idle screw is just completely out of whack but I can't find anything about how set it initally so I can then tweak it.

Have a qualified person service the carbs. They're gummed up.

Ok - I had suggested to him that it might be worthwhile to pull and get a rebuild kit for it, but we were short on time.

Plus I just talked to him and I guess the bastard couldn't help himself, even though I told him not to touch it and he backed the idle screw out to the point it acutally came off the bike. He said he started to pull stuff off and still can't get it... I am ready to tell him he's on his own

Looks like he's going to learn a pretty valuable (and possibly expensive) lesson...
