Arrow Idle and throttle issue, hopefully not too bad, let me know what you think.

First off my '07 250r and I have been through hell together, but then another lady came in my life the '09 ZX6R Monster Ed. and my ol' lady has been some what well neglected.

A couple months ago I noticed after riding her that the clutch cable had been hanging on by a few threads, and she sat for a couple weeks to a month when a replacement throttle cable came in. Since replacing the clutch cable the bike has had some trouble idling on her own without the choke. Before she sat alone and unused I had finished changing and replacing the oil and oil filter. The batt is fairly new with an initial charge of 12.97, I'd checked earlier. She roughly has 12,XXX miles on her and before these palpitations ran fine.

I have rechecked my work on the clutch cable and it's within spec based off of the oem manual. When starting I have the choke fully open and the bike is initially in neutral, the engine kicks over and rev's to about 6-7k rpm's on a cold start. I adjust the choke to bring the rpm's down and roll back on the throttle and bike wants to stall and shut offs shortly after. When the bike stalls and shuts off I wait a while and turn it on and I repeat the process again but I time the stalling out just right and roll on and off the throttle to get it rev with the throttle with the choke off and when I get to about 2-3k rpm's the bike wants to stall and shut off. I do this repeatedly until the bike has warmed up showing on the thermostat and watching the drain when the ignition primes.

Could it be that the carbs are gunked up or would the engine even kick over with the carbs gunked?

The 250r had not sat for that long of a time for the carbs to be shot. Any thoughts so I can diagnose the problem and fix or repair.

Yeah you probably thinking a lot to take in on the first post, but hay its better to get it all out from the beginning, don't you think.

I'll post pics later.

Could be the carbs. How long has it sat? The gas could be shit.

Not long, for a couple weeks on and off. I would start her up and ride around till the engine warmed up and turn off.

Right now I have run new fuel through and I have regained some throttle control back but not much. It does feel like the carbs need to be synced, the sound while on doesn't seem right and the exhaust pressure seems off.

Before I take the carbs out to clean I will try some fuel treatment to try and push that gunk out from the jets first, and if that fails I will definitely take them out and clean them its long over due.
