Immediately after WFO-9, Judy and I rode to the Portland area for a ride-in at GP Suspension on Monday. I had roughly 32,000 miles on the Wilbers rear shock and Wilbers springs I had put in the front forks at roughly 5,000 miles, and the rear was undersprung, especially 2-up. So it was time to get my suspension refreshed and done right, especially since I'd been smart enough to sign up for the last group buy last December.
Two things: (1) for three years, I've had a Muzzy 4-2-1 on the bike (supposedly after they fixed the dragging issue), and I have touched it down a few times -- only once 1 up, but it has made me very cautious of overcompressing the suspension on hard right handers; and (2) I have a Traxxion AK-20 front fork set up with a Penske rear on my Blackbird, so I already know that a top notch suspension system makes a big difference. The FJR was markedly better with the Wilbers than stock, but still -- esp. when compared to my Blackbird suspension, it just wasn't "right" and the pipe touch downs sucked.
Not any more -- the FJR suspension is now RIGHT!!!
Ben and Dave at GP are great! If you have ANY interest in how suspension works and why, you MUST do a ride in and see it done (and the lengths to which they go to make the parts necessary to make it spot on, perfect and right). Honestly -- the education is worth FAR more than what they charge ($0) for the friendly, no questions unanswered tour you get of the insides of your suspension. You will not be bored for a moment. Ben took me through the whole process as he did it. (And this is not something you can do yourself at home!!) Fascinating, and you come away knowing why suspension works or doesn't, and why what he just did for you works.
Among the interesting things was Ben measuring the spring rate of my undersprung rear Wilbers. It was a "10", which was supposed to measure 580 lbs. But instead, it tested 522 lbs at 1" and 542 lbs at 2" IIRC. Then he showed me evidence of my rear shock having bottomed out (probably a lot, considering Judy's discomfort on many occasions from getting hammered over hard bumps). Compare that to the 800 lb spring that Dave and Ben decided would be right after consulting me on weight of typical load and how I use the bike.
I also got an education on Wilbers' preloaded front replacement spring vs. GP's recommended spring with the proper rate without all that preload. In fact, Ben cut down the spacer on the lathe while explaining what he was doing and why he was doing it. This gave me the slightest, precisely tuned preload on the new spring, which I found out does exactly what he told me it would: give me a plush initial reaction to sharp hits, while having the new spring's stiffer spring rate take up the work when needed -- i.e., the best of both worlds.
And that's what the ride since has proven-- this is a night and day improvement. I now have heavier springs, but I have a plusher ride on the roadways, yet a much more stable and precise feeling carver of twisties. Judy is not getting hammered in her cervical spine anymore by what we now know was a spring that allowed the rear suspension to bottom out. Expansion cracks and potholes are no longer the jolt they were before. But best of all, the thing is really planted and predictable in hard twisties when I have to throw it around. I tried, 2up and packed for the 9 day trip, to touch down the Muzzy collector in the turns. Didn't happen. I'll try to slam it on a hard (less precise) line through a compression corner more, but I doubt I'm gonna be able to compress it enough to make it touch down again. And amazingly -- this does not seem to come at the expense of a harsher feeling ride, whether one up or two. The overall ride is actually MORE comfortable. These guys are GOOD, and they know what they're doing.
Can't say enough good about the suspension GP Suspension has given me, the guys at GP or the ride-in experience with the free education. Top notch folks who will be doing all my suspension work for as long as I ride and they decide not to retire.
