My flawlessly running, religiously maintained 09 Uly, now with 12,000 miles is on the blink. If anyone has any ideas on what might be causing this, I’d be grateful for any input. The problem surfaces pretty much immediately while on a 300 mile ride last weekend. Suddenly, when stopped and idling at a stop light, the engine began running very rough, the engine light came on and it started to die. I was able to get the Rs back up with the throttle, but at idle, the engine light comes on and it wants to die. It doesn’t seem to have the problem when the engine is cold and at start up, but after it reached full operating temperature, the problem persists without exception. The bike is still under warranty, so I will be taking it to the dealer this weekend, but for the sake of my own education, I’d appreciate thoughts from anyone with knowledge or experience in these matters. Thanks. (Message edited by Hangetsu on September 23, 2009) | ||

Vacuum leak (bad intake air seals) or bad Idle Air Valve (IAV)? | ||

I'd lean toward the intake seals. Once warm they allow extra air in that shouldn't. It wouldn't be noticable in a rich fuel mixture of a cold start. |
