Not all 12V batteries are the same. As stated by Greenbarn - you need a good battery. I think this is shorthand for high cranking Amperage.
My original Super MF FTZ16-BS was 12V 18Ah (78 months before replacement), this gives from memory about 220 Cranking Amps - which is what you need for two big pistons, each the size of a 4 cyl 750. A FTX of FTH will be 12V 14Ah which gives you about 170 Cranking Amps - enought initially when fresh, but tires easily with use.
I have had similiar problems with longevity/more trying conditions when I was told a 14A was sufficent - had to replace it within a year.

To elaborate, if the battery will only turn over the engine a couple of cranks, and then it's dead, then the battery sounds bad.  The 1500 takes a good battery to make the electronics work, and if the battery is low ( low voltage )  then it will not start.

Sounds like you need a battery.

Hi have a hot start issue. So I ride 20min or so in light traffic and stop to get something to drink, and the bike won't start I usually can get it to start on full choke after  three cranks when hot but this time It just drain my battery after a couple of good cranks.

I have powercommander VH longshots and big air intake the bike has 28k mi.
I have cleaned the throttlebody
Is there anything else I could adjust ????
