OK, so I'm signed up for the PNWGS Rally in Menlo WA (disclaimer, I'm a board member, but you should go too) this coming weekend, and I'm taking a advanced off-road clinic from acclaimed instructor Jimmy Lewis (more shameless pluggage). So I changed my tires, and being tapped out after buying my beeyootiful R1200GS, I changed out my Deathwings for a pair of TKC 80's...all by myself! [except for when I had to take the front to a tire place across the street for some hi-pressure air...but that was free, therefore it didn't happen...those are the BMW rules). 'cept I didn't balance them. I don't have a balancer, and after all the wrasslin' with the beads and the tire irons and the lube and the yadda yadda, I just plain wasn't interested in any more work. it was 2am and i was urgently needed elsewhere. But now, in the light of day and several hundred miles later, I'm thinking balancing might be a good idea. What should I look for to see if I'm in need of balancing? I ride on the road to work 3 days a week (90mi days), as well as offroad on the weekends. on road I keep it under 80, off road around 20-40 tops. How do i keep rolling happily along?
