Hard to tell with no more information than we have, but sounds like maybe it's not charging.  You say, if you trickle charge it, then it will start?   If you do not, then it "chugs away but will not fire". ??  The 1500 fuel injection system is very sensitive to a low battery.  They can turn over what SEEMS to be plenty fast enough that you would think they SHOULD start... but will not.  If you think it's cranking slower than normal, it probably is a low battery voltage, and the fuel injection isn't getting enough voltage to work properly.

You need to do some testing to see exactly what it is or isn't doing.   The battery voltage should always be around 12.6V for a charged battery.  This is with the bike not running.  So after trickle charging - you need 12.6 or close to it --   or else you have a bad battery (I don't care if it's "new", there are bad new batteries sometimes).   Once it's running - your charging system hast to be somewhere ABOVE 12.6 V.  Around 14.5 is considered "normal", but could be somewhat less.  Check this with no extra "accessories" running --  such as driving lights, GPS, heated seats, any extra lights, etc.

The Drifters do not have a real large charging capacity.  Do you do have any extra accessories?  or larger wattage lights? - you could easily exceed the capacity of the charging system --  I switched to slightly higher wattage spotlights on my light bar once, and ran the battery down-  while riding on a long ride--  and it would not start at a gas station.

I suggest (for everyone) to install a small volt meter so you can monitor the charging / battery condition whilst riding--  might keep you out of a jam. I have one on both Drifters.

My starter motor went out, at 167,000 and took the battery with it. Replaced both and trickle charged the new battery and took it for a 150K run (have a Vstr5om 650 which is much less effort for an aging bloke) so I no longer ride her daily. When I try to start , she chugs away but does'nt fire. New plugs, a little choke and I'm lucky if she starts/ dry plugs , sit , (maybe) trickle charge and away she goes.

Pain in the ass. What am I missing ? New leads ? Faulty alternator ? Anyone else had this ?
Thanks
