There apparently is a new engine module that has been released. Several of us have experienced the stalling and the new engine mode apparently cures the problem. I think it is covered under warranty. Best to ask your dealer.
Thanks Kim for thinking of the poll! I think statistics may help us and Yamaha understand the magnitude of the problem. I don't think their corporate office hears about all the stalling cases or they probably would issue a recall or 'recommended repair'.
I also am wondering if the engine module that causes the stalling also could be hosing the mileage (MPG).
Bad Module = stalling & poor MPG
Failing Module = bad MPG, but no stalling yet
OK Module = good MPG
Just a thought. . . . :dontknow:
FYI - I have had good mileage initially, then it degreaded, then it started stalling. Anyone else?
