I have a new California bike, and sometimes when I'm at a stop waiting, the engine sputters and stalls out. I've spoken to the dealer, he says there is some system that is supposed to lower the idle while waiting to conserve fuel, and that is what the sputtering is, but that it should never stall out. Unfortunately it does sometimes, and he's kind of at a loss and says needs to check with the RE guys to find out what possible problems could be. Just wondering if you knowledgable folks can offer up any ideas as well, while I wait to hear back.
Just about every time I'm at a stop, whatever system (he told me and I forget now) kicks in and lowers the idle, and I can hear it kind of sputtering, but then it's like some switch catches it before it stalls, and raises the RPM up a bit again. Maybe 1 in 5 times though, it doesn't get caught and the bike stalls. I've learned to just give it a tiny bit of throttle when I hear it sputtering and that seems to correct the problem, but seems like I shouldn't need to be doing that.
