Ok here's the deal. I've got a 2010 250 I bought a couple weeks ago with 1800 miles. It's warm where I live and my bike starts up with no choke just fine and idles ok. Set idle to 1600rpm. When I take the bike out for a ride it does fine, power feels good through all ranges. After all warmed up, if I stop the bike for a couple minutes, the rpms slowly start to fade until the bike stalls and dies. I posted this in another forum and didn't get too many replies. Is this a problem with the carbs? Could they be dirty? I checked the air filter and it looks good....
Quick update: I haven't ran the bike for prob 6 hours or so. I went out and started it(easy) and let it idle. Idled beautifully at 1500rpm for around 4-5min and slowly died off. WTF???
Could start it again, but slowly dies off each time. Revs up just fine.
Please watch this video and HELP!!!
