Guzzling will work and it will let you turn off the O2 sensors that I bet is your CEL problem.

My V7lll will do this if the tank is full or near full and has been parked in the sun. There is a cure but it has done it so seldom and is not that big an issue so I haven't bothered to address it.

That would be my first guess.  I keep my bikes in a storage unit, and since I don't ride them frequently, I tend to keep them topped off when I park them.  When the temps are hot here, I'll crack the gas cap open to let it vent for a few seconds before starting.  Whenever I've done this, there's always been that "psshhh" sound of it depressurizing.  The warmer the weather, the louder and more forceful the sound.

Friday was hot here and the bike was in the sun all day.
I fired it up to and it stumbled and died. (check engine light turned on)
I tried on more time with the same result.
So third push on the start button i gave it a blip of fuel to keep things spinning, It still stumbled, gave me a lean pop. and then slow settled down and ran correctly.
The bike ran just fine for the 20 mile journey home.  And ran fine back to work this morning. (light still on)

So i think its time to get the necessary equipment to run diagnostic test.
Q1.  Will a standard auto OBDII reader work with correct interconnect cable ?
Q2.  Would GuzziDialog software and cabling be a better option ?

Your best bet is to go to Griso.org and follow the link there for the Lonetech cables and adapter, read the info and download the correct programs. There is the GD base program, plus a 'reader' to dowload and 'writer' to upload maps to/from your PC.

The Lonetech cables are Proven and work the first time. People who try to patch and match always have issues.

I bet sitting in the sun, your tank had a ton of pressure build up. GD is a great tool with many functions and tests.
