Rough running 2000 GSXR 600?

[Daniel F]

I have a 2000 Suzuki GSXR 600 and it runs rough at idle and stalls out when it is not choked. It almost sounds like one of the cylinders is missing every once in a while. We already went through and cleaned the carberators, retuned the air/fuel mixture screw, I got new gas, I changed the spark plugs, I ran it without the air filter to make sure it wasn't clogged. I get the same results everytime.

You should also have synched up the carbs, checked for vacum leaks (lines, manifolds, loose parts).
If that doesn't do it - take a plug reading to find out which cylinder is missing.

You ran it without the air filter? That's a good way to screw something else up. Why wouldn't you just replace or clean the air filter?

If the carbs and filter are clean, and you are getting a strong spark, I would suggest taking it to a dealership and having them take a look at it.

have you turned the idle jet? You also may need to check the timing.
