In the thick of it
I have a problem with my 2006 Honda CBR1000RR. Recently I noticed some oil dripping down one of the tubes on my forks. Being a mechanic, I didn't think much of it, dropped the forks, and replaced the seals. I had some 15-weight fork oil on the shelf, so I used that to refill to factory level. Before that, everything was gravy. I had fine tuned the suspension a few weeks ago. However, when I reassembled everything and went for a test ride, after the tires were warm I pushed it around a little bit. The bike now understeers like one of those cheesy Smart cars. I have the preload topped out on the front (I'm a big guy, topped out is exactly factory sag) compression is at about 80 percent of max, and rebound 45 percent (the rebound damping on this bike is very overpowering I've noticed, even more with the 15-weight). I'm using Pilot Power 2CT tires. The only other change I've made is raising the forks a negligible amount. They used to be 4mm from the top, and now they're topped out. Turning down the damping for the 15-weight oil isn't helping much. If you tip the bike in the corner, it washes pretty well, but throw in some throttle and you can get into a hellacious drift. What in the world is causing this?
