First, two occurances of note. I replace my brake pads over the weekend, a 15 min job. Noticed that the left front inner pad was worn almost to metal. The rest were down to around a couple of milimeters. Also, 2 weeks ago the biked tipped over from the centerstand. But I hadn't noticed any control problems after that. The problem occured at around 45mph, I took my hands off the bars to straighten my gloves and the shake began. Pretty violent, but I grabbed the bars and held them steady. The shake dissapeared. Got it to happen once more at about 25mph right after that, but couldn't make it do it again. What's up with that? As I looked thru the previous messages, could my new Corbin hard bags really have that much affect...
