I'm going to throw a bit of a curve ball in here but I am glad a few are interested in talking about suspension as I recently started playing with mine (the suspension settings!
) and noticed a stark change.
So last year, shortly after buying my FJ and reading this post, I made the changes to the suggested settings and yes, noticed a big change, mostly when I came to a stop and how rigid the bike now felt. But, I hadnt the experience on this beast to appreciate the handling changes.
While at NAFO, I couldn't help but notice how the majority of riders all had a little sticker from Portland on their front forks. I also had to contend with the humbling reality that I hadn't a hope in hell of maintaining pace through the twisties in Kaslo to New Denver with a couple of riders half my size and twice my age. Graciously, several people pointed out that it wasn't so much my riding ability as it was legendary skills of Petey and Griff as well as their tuned suspension I was trying to match.
Nevertheless, I decided to really read up and experiment with my stock suspension ( now pushing 25,000 miles) after that event.
I am 6' 4" and with my gear on I am easily 275 pounds. Ive always found it difficult really leaning the FJ over on a tight turn and I have never scraped a peg. I am also very unbalanced and hesitant in slow speed u-turns or parking lot maneuvers. You'd think someone with my leverage and weight wouldnt find this so difficult. So, borrowing from what I've read here and from "Suspension 101" that Steve at NAFO provided, I started experimenting.
I changed the suspension settings from what they were too full soft and rode around for a day. I then went to the opposite end of the spectrum. I wanted to make sure I experienced a full range of riding conditions but also wanted to ensure that I wasn't fooling myself in believing a change in bike behavior in one direction or another simply because I was expecting to notice a change in one direction or another.
I then proceeded to change ONE adjustment to the more extreme setting on the opposite end of what the rest were (despite reading Haulin Ashe warn about how this can lead to unpredicatable results) simply to see if I could observe how THAT particular setting changed things. I fiddled with settings over the course of a week or more. Often I would change one or more setting after a ride knowing I wouldnt be back on the bike for a couple of days hoping that I would forget what I had changed and wanted to see if I could really notice it. I suppose I was concerned that much of my observations were from preconceived ideas of what should happen. This technique actually DID work pretty well.
I found that rebound and compression settings were very subtle to observe except when coming to a stop. I could visually see the rebound settings by how long it took the bike to settle but it was subtle. No way would I notice if someone surreptitiously changed the dial on the bike say 5-8 clicks in one direction or another.
Compression was as much of a feel, especislly during braking and stopping, but again, not something I would notice if someone changed the settings a moderate amount without me knowing it. I also didn't notice an unbalanced feel when one was set to really stiff and the other to really loose.
The preload on the forks and the swing arm really made a difference though. And this is where Steve's explanation along with reading some sites that really described the science of bike suspension helped me to understand why. Up until now, I wasn't having a lot of success in experimenting with settings which resulted in an appreciableg difference, save going to extreme soft settings all around. (By the way, my rebound adjustment has 25 "clicks", my compression has 37 and my rear preload has 50). When I had adjusted these to all the way soft, not surprisingly the bike had a very 'floppy' feel to it and there was no doubt it was noticeable. It wallowed and didn't track straight through a curve. It was also spongy/bouncy on uneven surfaces. However :search: , the FJ seemed to WANT to turn now. It liked leaning and whats more, it didn't want to straighten itself up. I wasn't expecting that. I also noticed the vibration in the grips much reduced ( I recalled thinking 'that seems weird' when I first read how others noticed vibration was reduced when stiffening the suspension). Despite the drastic change to the feel, the bike was obviously too spongy in this configuration and I ended up putting the preload back to 2 on the front and 8 or 10 on the rear and continued to make subtle adjustments each day as well as experiment with the "HARD-SOFT" lever. After a week, I was beginning to get frustrated experimenting with different settings and still not finding something that gave me the feel or confidence to bring the bike over enough to drag a peg. I figured I was just going to have to make a trip to Portland.
Finally, I stopped to get gas (Premium unleaded of course! :blush2: ), and decided to make one last tweak. I brought the front preload down to 3.5 and softened the rear from 10 to about 25 (clicks out from all the way in). Then it happened! Somehow I stumbled upon a balance I hadn't before and - no word of a lie - it was like a different bike. Just when I was about to concede that all this suspension fiddling was nonsence and more of a placebo effect, I found a setting that allowed me to drag a peg - easily!
The change was so drastic that within miles, my driving style even changed - if that makes sense. The bike wanted to go into a turn but, it tracked through it. Vibration was gone. It even felt significantly different under hard acceleration. It felt smaller, tamable and made me feel more in command. Most noticable was maneuvering at really slow speeds. I no longer felt like I had to drag my boots on the ground fo fear of the bike suddenly wanting to fall. I did notice the bike had a bit of a bounce when encountering dips in the road and, when I acquired a passenger, it was too soft feeling and had a bit of a wallow in turns - even when I switched over to HARD with her on the back. But overall, I am much happier with the bike in this configuration. I am still going to tweak around with the settings and consdier aftermarket shocks eventually, but for now I will continue to enjoy my 'new' FJ.
My point to this tome was to not only desribe my recent experiences with stock suspension settings but to also remind riders experimenting with theirs not to get hung up on an idea from someone else so much so that they lose objectivety. Ive been riding around for a year with settings that seem to be the 'norm' by most users that post here and that acceptance caused me to dismiss experimenting and realizing there was a better setting for me. I still don't understand why this seemed to work so much better. You'd think with my high center of gravity and extra weight, my bike would need to be that much stiffer than others but its not the case.
I doubt I'd be able to keep up with Petey and Griff now, but I would certainly have a lot more fun trying. :thumbsupsmileyanim:
