Do you already have the GYTR competition ECU? Otherwise GYTR programmer won't do you any good.

Some people have cured starting issues by upping their CO / Idle setting with the Yamaha FI Diagnostic tool (PN 908900318200).

Doesn't sound like the tuner would help. If the kickstart is working, then the EFI components are doing their job. If the electric start is not working it is usually the battery, the solenoid, the starter, or a bad connection between one or more of these.

When it's really cold out my 12' WR w/ Comp. ECU is easier to kickstart in the mornings, and even warm occasionally wants a second stab of the e-start to fire.

Agreed, check for an in-line fuse that may have gone bad?

If it is more of a temp related issue I would check the intake valve clearance as well. Tight valves are hard to start. Also, do a load test on the battery. If it is weak it is not spinning the motor to the proper rpm to fire.
