Enjoying the first real spring day of the season: Fueling up for a ride with Mr. Slow.
I’m not happy. I was at first, but am not anymore. I was lubing my chain the other day and noticed that the rear sprocket is showing signs of wear, this led me to look into a gearing change, since I’ll have to replace the sprockets in the next few thousand miles anyway. This research, in turn, got my perfectionistic side all bent out of shape because I’m about to change yet another thing while I have one kink already to work out. One thing at a time, chica. One thing at a time. Thus, it came to be that I had to admit to myself that the suspension setup compromise is not working for me in the long run. But I really don’t want to go through that whole crappy fairing and fender removal process yet again. What a bummer that is. Heck, it isn’t really working for me at all, now that I had a chance to put a bunch of miles on the bike. Don’t get me wrong, I love it lowered like it is now. I’m more confident at slow speeds (even though my turns are wider than they used to be) and I can actually flat-foot the thing in my race boots now; no more getting stuck on the incline side of a crowned road or trying to back out of a declined parking spot. She also feels more stable and planted. However, when I first started this project I hadn’t realized that maybe the adjustability range of the ‘Busa would give me problems and would lead to compromises. Lesson learned. Check the parameters before implementation to see if it’s even possible to follow through. It was a learning experience (and still is), and I wouldn’t have been able to ask the right questions at the time anyway. Yes, I could have asked for help and had the answers given to me, but that’s not how I work. I want to own my solution. I want to be guided, not shown. The Socratic Method, that’s how I like to be taught. I had to take it one step at a time, and I’m not sorry that I did. However, I am now frustrated with the current setup. The bike now corners like a bus and my arms are really getting tired from the heavy steering, at least that distracts me from my sore thigh muscles. 😉 My geometry is way too relaxed for my taste, since I am missing 10 mm of preload in the front, but the adjusters are at their limits. I don’t want to spend more money on this… I have to sleep on it, but I think the best I can do is raise the fork tubes through their triple clamp 5 more millimeters and crank in rear preload. Between those two, I should be able to affect the desired decrease in rake/trail. I’m dangerously close to getting into the no-no zone up front and I’ll blow my rear sag numbers into race territory, but I think it might just give me what I need. If not, I can always move for a reversal.
