I do use a fuel additive on occasion, but I've experienced the same issue even with treated gas.
I have a LiFe PO4 battery (Ballistic) which don't like to start in the cold weather. Took the battery home, let it warm up and put it back on the bike and it started in the first attempt. MacBandit said that the bike will do some weird shit when its not getting the right juice. I am changing my plugs too, copper do need to be changed out more often, and getting 10k+ is probably over doing their longevity, so hopefully that's your problem.
Great point. There could be the possibility that the battery is right on the borderline. Right now, I have a BikeMaster TruGel battery that's over a year old. I'll do some voltage tests to be sure. But I've never had this issue with dying batteries, stators, or regulators in the past.
I'm always able to get it started eventually with jumper cables. But the last few times I've had to jump it, it's cranks over longer and longer before it actually fires.
I'll pull the plugs and check em out. I doubt they are fouled or anything, but they are probably just worn out. 10,000 miles on copper plugs with a motorcycle is a lot.
I'm gonna try and find a set of NGK Iridiums this time around. I thought about experimenting around with e3 Diamondfire plugs, but they have regular copper electrodes so they'll wear out just as quick as the cheap ones.
I'll post an update in a few days to see if I notice any difference.
Thanks for the help guys.
