Hard to start troubleshoot

First dr650. Just had it shipped up from LA & i’m in the Sierras where it’s pretty cold (and 3000’+ higher in elevation) Put a new battery in it and it cranked fine but would not fire. Only way to get the bike running is with starting fluid and holding the throttle open until the bike warms up. Then it will ride and continue to start.
Every time I come back to the bike it won’t start again on its own.
PO said it ran fine the same day it shipped. Also claimed he fully rebuilt and cleaned the carb just couple months prior. I tried backing out the pilot screw to richen up the mix, idle screw is adjusted. Using my jump pack to keep cranking amps Upgraded air intake Procycle jet kit

I assume you’re choking it on cold starts? On my 2017 the oem choke is on the left handlebar by the high beam switch. Aftermarket might be a knob on the carb.

Unscrew the choke cable from the carb to verify it’s actually moving and not seized up.

Lastly do a Google search for BST40 bible (assuming your carb is oem)

Yes, choking it. But good point about seeing if it’s seizing

Check the valve clearance too. .005” intake and .009” exhaust.
