I have a yamaha vmax 700 triple and assuming the rear suspension is basically the same...there should be these collars like you said below your springs...it should have notches for whats called a preload wrench ($10-$15 give or take)... On the bottom of the collar (the part not against the spring) there should be a staircase type thing...the higher the collar sits on that...the sitffer it is...sorry its really hard to explain how these things work/look without pictures. If you weigh 238lbs you want your sled closer to stiff otherwise if its on soft, you'll compress all your travel...Im 180lbs and on soft mine compresses quite a bit. However, too hard and it will not absorb bumps...your best bet is to experiment with different setting and find what you like best.
I just put a 3 1/2 lift brackets on my 99 vmax 600sx, and it seems like it is rubing in the front, only when I try to give it a bit, mabe 1/2 throttle, it has good hight from the top of the tunnel. Im 225lbs,
I have a 1.25 track on there, the straps look like they are loosened all the way, and both shocks are at aprox half way, the two rods, with adjusters on them, in back outter suspension are loose to, (by hand),
i didnt put drop brackets on the front of suspension, just the rear.
I ditch bang, not a trail rider.
how do I fix this problem, is it the track size, or anything i have mentioned here??
Thanks for any suggestions
