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 PumpMore 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.
