Recently began experiencing the following symptoms on my 2004 dl1000, with 44,000 miles.
On very hot days, usually, and after some miles the bike begins to run rich, stall at low throttle opening and cough and belch. I have had the bike in to the local dealer, during their diagnosis they hooked the laptop to the bike, rode it, it acted up but they say the computer caught nothing unusual. they checked valve clearances, throttle body synch and TPS, they then installed the updated Engine Control Module at my request.
Picked the bike up on a Friday, rode it Sat. and it ran perfectly, high temp in upper 80s. The next day, Sunday I went on a 200 plus mile ride with friends and all seemed well. Stopped for a water after a 1 hour leg of our ride and when I restarted the bike it once again exhibited all of the prior symptoms, air temp was near 100. Took it back to the dealer on monday, they rode and no problems. They spoke to Suzuki who said there is nothing else to try, just ride it.
Has anyone else had such an experience and if so, what was the remedy, short of selling he bike. I wonder about the Intake air temp sensor and the effect high ambiant temps plus the soaking effect of engine heat on a 5 to 10 minute stop may have on the sensor, it doesn't clear itself after i run it for a while. But will be fine the next morning. Any thoughts?
