Being fairly new to dirt bikes I have never played around with the suspension on my 2009 610. I have been playing around tonight with the rear shock trying to set the sag etc but I'm not sure if I have done it all wrong. At the moment I have the spring screwed right down so only about 1/2 inch of thread can been seen under the adjusting screw. Seems to be wound a long way down or is this normal? Anyway at this setting I have about 95mm of races sag and 30mm of free sag. According to the net this seems about right? Next problem is the high and low speed compression adjusters do not move independently of each other. When I screw the outside knob the inside turns and vice versa. Doesn't seem right? I have tried holding one and turnig the other but they are definitely locked together somehow. Then it took me an age to find the rebound adjuster. I assume that is it on the LEFT side right behind the Swingarm so it is impossible to access? How the hell do I get to that? Lastly can anyone suggest some good settings that I can use as a starting point? Thanks in advance
Just have a suspension tech do it for you! It will be the best $300-$400 you spend. You'll be able to ride much faster in the woods.
I like 105-108mm rear race sag. The stock spring is pretty stiff so it may be hard to get both sag numbers in the ball park. If you put a tie down strap through the wheel and around the seat then compress the suspension, there is a point that the adjuster can be accessed.
Ok thanks. Good idea using a tie down strap. I realise that taking it to a pro would be best but I would like to try myself first. If all fails then they can fix up my mess! Does having the spring screwed way down seem right? Also any ideas on the compression adjusters moving together? Cheers.
If you have a buddy handy to squish the back down you should be able to get to it too. I don't know what you mean by "screwed way down".. Picture maybe? I try not to preload more than 15mm. If you only have 90mm race sag, you could unscrew the adjuster to at least 100mm sag. I have mine at 108. How much do you weigh? The stock spring is good for about a 225 pound rider. Do you think it is the original spring?
yes sorry i was not clear. i have the preload on the spring wound down to near the end of the thread. i am the second owner and bought the bike stock (or so l iwas told). i am 95 kg (210lbs) so the stock spring shouldnt be too far off. ill try backing it off to 100mm of sag but then wont the free sag be 40mm+? any ideas on the compression adjusters? thanks
yes that seems like a lot on the spring for nly 95 of preload, you may/should go to another spring. I personally dont like to have the adjusters down that far to get sag correct. As far as the high amd low speed compression, when you turn the knob(HS) the inner adjustment (LS) will turn w/ it, but it does not change the original setting of LS
A poster somewhere suggested placing a ladder on the ground and running over the rungs at various speeds to tune out the initial several inches of deflection and chatter that most of us try to get rid off....great advise......at least on that area of softning the first 2-4" rocks and ruts we always deal with on the trails. If one does both wheels air off of big whoops and such then setting up for no bottoming is important. I personally took about 1/2 of the preload out, for my 190lbs, and took out (counterclockwise) almost all the compression H/S & L/s damping........and I really like the way the rear end acts. That gave me about 4" of sag. Someone has mentioned they heard Husqvarna used the 6.4 OEM spring to handle "up to" about a 240lb rider.......so to have the preload cranked all the way down......or close to it, would seem to make the rear pretty stiff.
