jrfuisz said:I'm not mechanical guru, but my M620 would stall when it was hot (DC's summers in stop and go rush hour traffic). That was a function of a slow idle though. Other M's had the same issue and there was a lot of chatter when the 620 came out about stalling and idle speed. It was almost a universal fix by raising the idle speed (which is never that percise anyway hence the range the manual always gives you) ever so slightly.
With the ODB system if there was an o2 sensor failure or the like we'd see faults and there would be an easy fix (identification of the bad part.) There is not from what I can tell so the bike has to think it is operating within a normal range - hence back to idle speed.
My best guess - not having picked my bike up yet - is that the dile speed needs to be raised on some bikes. Which would mean people with stalling bikes turning to page 23 of the manual and raising it ever so slightly.
Can we get people to post their idel speeds - especially for those with problems? Have you tried raising it and have you found something that works?
