I have checked all the self help topics and couldn't find the answer to this. The rear disc is much hotter than the front after a ride. I can put my hand on the front disc but I estimate that the rear disc is 250-300 degrees. When the bike is on the lift there seems to be noticeable drag. Doesn't just spin like the front but I wouldn't expect it to with the tension of the belt. What's up? New bike and approximately 2k miles. Thanks for the input.:worthy
