hello i have a 99 gsxr 600 that won't stay started. i went to ride it the other day, i let it warm up for a while, took it around the block then it just died on me. and now when you try to start it up it has a rough idle and i have to have the carbs all they way open in order for it to stay running. what would be some of the things to check for?

1. bad gas
2. vaccum leak
3. spark plugs need to be replaced

just looking for some input on what to expect to fix first. thanks

 

I'm not an expert, but it could be a few things. I had a similar problem on mine and it ended up being an air/fuel mixture problem. You may need to have the carbs tuned.

 

sounds like a wierd question, but has the bike been painted or anything? can't count how many time's i've seen painters plug up tank vents lines. There's a big line running from the bottom of the tank to... nothing. find that line and see if you can blow thru it. Sounds like the tank is vaccuum locking. No fuel.. no run....

but yeah, there's a hundred other things it could be, just easy to start with the simple stuff.

If it is clogged, you can either clear it out, or take the gas cap off and drill a tiny hole in the tank to vent it, under the cap, preferrably on the right side of the cap, so it won't drain rainwater in if you have to park the bike outside and it gets wet.

 

How long has the bike been sitting?

Carbs probably need to be cleaned.

sounds like carbs

 

i would try cleaning the carbs first....

 

does it idle off the choke after it's warm? kinda a dead give away if the carbs need gone thru or not. Pilot jets clog up with a quickness,

 

carbs.......

 

Hey man try the battery 1st then if thats not itthen if the bike has been sitting you need to run the piss out of it and it mite be the carbs but it depends on alot of things i mean i work on them all the time so if you need a little help give me a holla

 

wow... "run the piss out of it" ya that ALWAYS makes a bike run better.. since the bike is running super lean..... hints why its cuting off.. its running out of fuel. just clean the carbs and replace the spark plugs..


on another note.. me, shane(emcracing) and steve(skr00zloose) work on motorcycles for a living.. what do we know
