Although it might be a little late since you already ordered a battery, + 1 for Batteries Plus Bulbs. I had some of the exact same symptoms as you are having. Hadn't really thought much about the battery, but one day, it just gave out. I did a bunch of research and decided to go with the Batteries Plus lithium battery. It was a direct fit,
3 year non-prorated warranty, no core charge. Granted, it was about $170 or so but haven't had any starting problems whatsoever, hot or cold, since I installed it.
World of difference! We may not be
quite as hot as your neck of the woods, but we've been in the 90's -100's consistently for the last couple of months. I know it's pricey, but $170 is a small price to pay, imho. Plus with a 3 year nonprorated warranty, I figure that works out to about $57 or so a year. I was tired of going places and
hoping it would start when I was getting ready to leave. The only issue is that the battery instructions say my bike/alternator has to be putting out I think 14volts but it's only putting out 13.5 -13.6. But I figure with a 3 year warranty, I have time to figure it out, lol.
That being said, I still have the the slightly higher idle when the weather
and bike are hot. But if I remember correctly, I think temperature changes the density of air. So I attribute it to that. (lol, ignorance is bliss, right?) But just in case, I'll be following this thread
And of course, your issue may be one or a combination of all the other suggestions from this
extremely knowledgeable and
very helpful group. Never ceases to amaze/impress me.
Best of luck.
ps - I've always absolutely
loved your bike mailman. It's one of, if not, my favorite.
