i've got about 75 hours of ride time on an HDR and it has developed a clicking sound and feel in the rear wheel. its most noticeable when leaning the bike over to the left and weighting the back while riding. but I can also feel the clicking resonating through to my crank/pedals as I coast straight down the street. i've removed the brake to troubleshoot and i can't find what the problem is. wheel bearing? any one have experience with this?
