Has anyone ever heard or done this to there boxxer. taking out the spring in the right leg and putting a sid schrader top cap and then just adding air. it gets rid of the spiking.

uh, I guess you could do something like that but it would have zero effect on spiking. Changing the spring medium (coil/air) is unrelated to the speed with which oil can pass thru the ports in the damping piston (spiking).

Use more or a heavier wt of oil. I am not sure what the Boxxer comers with, but most have from the factory between 7.5 and 10 wt oil in them. First, I would check the condition of the current oil you have. Clean? Enough in there? The right stuff? By right stuff I mean good fork oil. I prefer Motorex- hard to find but it has no seal swelling crap and does not foam up. If all this checks out, try going up in oil height - then try oil wt. then try jumping smaller things!

There are a ton of threads on RS "Black Box" tuning. Someone was even saying that RS has instructions on their site. Oh, one more thing:

Boxxer + air preload = DEATH

Changing oil is a good idea. I'm a big fan of Rock oil and Silkolene (much easier to find). For 03 boxxers, there is a tuning guide on www.blackboxracing.com...they list a part kit that RS sells to change the rebound basevalve assy. The other part of the problem is that the free bleed port on the compression assy is too small. it must be enlarged to ***I THINK 1/8" *** call RS/sram for that for sure.

For 01-02 and 04, just using nicer oil is key. THe damping is spot on with those.

In 03 I'm a big fan of 2.5 wt oil in the rebound once the fix is done.
