new battery, on a tender, full headlight power.  After the bike sits for a few days she won’t crank over when I push the run.  All safeties check out ok.  If I hold the run button down for 20-30 seconds it will then engage the starter and turn the engine over a few times then stop.  After doing this numerous times till bike is warm she will generally fire up and run great.  If I turn her off warm she will still wait 4-5 seconds after run is pushed before firing the starter. But eventually cranks and starts the bike.

Now,  wait a day, come out to a cold bike and it all happens again.

I haven’t got out the multimeter yet but I’m thinking since it has something to do with the bike being cold or warm it must be electrical in the starter relay or rectifier?

Any help is appreciated.

I keep a battery tender on it.

Check for loose connections at battery,starter,starter relay and grounds. After that check for a parasitic draw on the battery. You can find and fix it and you will understand your bike better and you might learn a few things along the way. Do not hesitate to ask questions !

Shoot it under the seat, towards the intake snorkel.
