raising kit for rear suspension?

Hello KLR collective... I've re-found the DSN KLR650 sight after many years of being away (okay, maybe just a few). I used to be an active member here back before the list went "yahoo groups". Good to see some familiar names. Anywho, I have a question for you guys. Does anyone make a kit to raise the rear suspension of the KLR, using shorter dogbones? Basically a reverse of the lowering kit that is out for the KLR. If there is no kit, has anyone tried manufacturing shorter ones? If so, I want details! :) They look relatively simple to make, it is just a matter of getting the right length I imagine. Why do this? I'm a heavy guy, got the preload and damping on max, and would basically like to have the back end up a little higher when I'm on it and all loaded up. I imagine that perhaps this can change the geometry on the suspension, maybe the spring rate as well. Any potential problems that anyone forsees? Thanks for any input Carlos Milwaukee [Non-text portions of this message have been removed]

The only reason I know of to make raising links is if you lace up an 18" rear wheel. If your rear suspension is sagged out with a heavy rider aboard, you have the wrong spring installed. eshocks.com has 9" x 2.25" springs in a lot of weights. If you're around 250 in full riding gear, a 500ln/in spring would work. Springs cost $90, installation (if you remove the shock and bring it to a shop) about $40. Basically, with you and your usual load on the bike, balanced on the wheels, the rear end should be sagging 3" from absolutely topped out. Then, with just the bike balanced on the wheels (no rider or "luggage" but any tools that "live" on the bike on board, you should have about .5" of sag from topped out. I have been told by suspension tuners that a spring that meets both tests is correct. Most people just buy the denniskirk.com spring tool for $50 and change it out themselves. The stock spring is very hard to get off, and kind of dangerous because it's under a ridiculous amount of preload. (it's a 10" spring fit to a shock that's meant to take a 9" spring). Ironically the much heavier aftermarket springs are a lot easier to fit. BTW that's rebound damping, not compression damping. If you have it cranked to the max it will prevent the shock from returning all the way before you hit the next bump, and will actually increase bottoming. -- Devon Brooklyn, NY A15-Z '01 KLR650 '81 SR500 cafe racer "The truth's not too popular these days....."

Thanks for the info on the springs. My shock is still in excellent shape (from a 93 KLR with 38,000 miles, can you believe it!)so it sounds like something I should really consider doing. Now, there is one other thing that I didn't mention before for fear of seeming vain....I kinda like the idea of my bike just being taller. I think the KLR would look a lot meaner with the tail end a bit higher, even with no rider on it (basically higher static ride height). Would shorter links to make it a bit taller sound like a doable idea? I mean are there any huge no-no's involved that somebody knows from experience? What I'm thinking is maybe around an inch higher ride height. Just some things I can think of would be that the bikes handling might change some since the overall wheelbase might be a tad shorter. I'm not sure how it would affect the progressive nature of the rear linkage, or if it would change "felt" or "perceived" spring rate. I'm also not sure if shorter links would cause any undue stresses on the suspension. Any thoughts? --- In DSN_klr650@yahoogroups.com, bigfatgreenbike wrote:

I agree with Devon, the proper way to correct your problem is to tune your shock. BUT I do have plans for a raising link that an old lister sent me. It is untested so use at your own risk, if you screw something up, break your bike, or leave your children fatherless, don't blame me. http://www.borkbork.net/pics/lift.jpg Z DC A5X A12X

It sounds to me like the KLR fits your price point and needs pretty well. The DR-Z400S might be a tad small if you want to do much highway traveling, though it's a blast in the dirt. The DR650 is good, but needs a bigger gas tank. If your dirt work is smooth roads, the 650 V-Strom is a nice bike. Wouldn't take it on rough roads, though. It's hard to go wrong with a KLR, especially with all the support you can get right here from the group. A little luggage, a little camping gear, and you can have a pretty nice weekend away. __Arden
