Hi Gang I put the Rider comfort kit on my 06 Uly this week and I am very happy with the difference in how little the fan runs now. I do not hear it running while I go down the highway in 50 degree weather anymore. It is recommended that I get a new calibration in my ECU to optimize the cooling capabilities of this new shrouding. Has anyone done this yet and do you know if they are playing around with timing or fuel mixtures at all. I really like the way my bike runs and do not what to have the performance or fuel economy affected by updating the ECU Thanks in advance H.R.
