Looks a tad rich to me.

Is it running well?

Main problem is that sometimes when I hit the gas It will stall and die, might be a rich mixture?

More than likely. I would contact Dasa and give them your location, altitude, etc... and maybe they can help you fine tune their Dobeck system to better suit you. Or you could even reach out to Dobeck themselves.

For now, keep a few spare plugs with you while you are riding, and be sure to change the oil frequently just in case fuel is contaminating the oil some.

Well I cant really get to Dasa because I live in europe and not US,I think I might try leaning the mixture a little bit from the Fuel controller , not sure which mode I should lean out tho? There are 4 modes, Low Rpms , Mid rpm, high rpm , and Accelerator Pump

I am not sure either as I have PC5. I would shoot Dasa or Dobeck an email and explain to them what is going on along with your location/elevation.

Someone correct me if I am wrong but I believe the factory PCM has different settings from 2015 onward so if they gave you a tuner setup for a 2006-2014 it could also be affecting your fuel mixture.

If you do decide to play with your settings be sure to write down what they are currently.

2015 and up have different fuel maps. Sounds like it is lean around low rpms. This is common on them stock, they will shut off on low rpm when you give it some throttle under no load.
