I am having alot of problems with my rear swapping on me in the air. Small doubles I can feel it big stuff it scares me. Almost side ways on the landings. Its not rebound or sag, I have played with these all day and still getting me bad. Other than this the suspension is amazing. I am 6'4 250 pounds and my sag is at 100-105. enzo recommended 105mm. Just dont know what to mess with to make this go away and it happens alot worse on Jumps when I am hard on the gas. Bike never did this before but just bottomed like hell. So Help me out guys.

It sounds like your rebound is a bit fast. Have your tried turning it in?

I would call enzo and ask for some help.Chances are they have had this problem already and can help you out.

Wish I could help but my suspension knowledge is as extensive as my knowledge of nebular eclipses. I would normally say that the shock rebound is too fast but you checked that. I'm lost, sorry, Holmes. Ask a carb question next time, I can hook you up there. :lol:

I'm hardly a guru on the subject myself. Does it always kick the same direction, or will it just take off either way?

Rear wheel alignment faults can lead to this, as can either excessive compression damping or too little rebound.

Check in at the suspension forum.

I would take or send it back....You pay good money for expert work, I would expect nothing less than expert results...

This has not been asked....how are you lifting off the jump?
just straight on
semi scrubbing the face
shifting your weight from rear to front or possibly sideways

Have someone else jump it - the better/more expert the better...check results.

what spring rates did Ross go with for you? Did they revalve both ends?

revalve was done on front and rear. Springs are .50 front 6.2 rear. Race sag is dead on as well as static. On the fast jumps and an usually coming from Back to front hard on gas both hitting jump and landing. My lat times seem to be much better on this track this way. i have never had this issue before. The more I load the suspension worse it does if I hit the jump slow not at race sppeds just screwing off in a higher gear it will not happen. i have talked with enzo done some changing that has not helped so far. i am going back to track this afternoon and freeze my butt off to try to get this corrected.:ride:

I think a post or two got deleted...weird.

Anyway, start simple:
check your wheel alignment
spokes OK?
tires/traction/technique - i.e. i get a bit sideways if i am sloppy or real late getting on the gas on a jump face sometimes

Im going to second Grayracer and check the rear wheel alingment. It doesnt have to be very wrong to cause weird stuff. Especially if your hard on the gas up the face.

What was the suggested rebound setting? and how far did you turn it? and which way?

I agree with the others first check front and rear wheel alignment using a measuring tape, not the alignment marks stamped on the rear swingarm. I would also check your chain tension make sure it's not too tight. Recheck the torque specs on all of your suspension nuts and bolts to make sure everything is not too tight or too loose. I would also return all your suspensions setting back to the original ENZO settings and then start with one suspension circuit such as the just the rebound circuit on the shock, ride your bike, return the rebound back to the original setting and then adjust the compression on the shock, then high speed circuit, then work on the forks. I know it's a lot of work but you it will help isolate the potential fix.
