I used my heated vest for the first time last fall, and found that the vest temp varied a lot during my trip, and seemed to depend at least some on how fast the motor was running. That's not what I expected. I was wearing it over a long sleeved t-shirt only, then the vest, then a Darian over that. There was a ton of variability...sometimes very warm, others pretty not warm. I had it hooked into the factory power outlet on my 03 KRS, with the two setting cord that came with the vest. No Heatroller or anything like that. Anyone else shared this experience? Is this something I should look into on my bike, or the vest?
