is there any way to make it a lil stiffer? and if so how do you do it for the z400...

 

On the bottom of the shock near the shock mount there is a small adjustment screw. Flathead screw, just above it there is an "H" for harder, turn it that way, or a "S" for softer, turn it that way. I believe there's also one on top by the top shock mount but I can't remember exactly.

 

Blaster2fast , what is your rear shock doing ? It would be easier to help you adjust if you explanned what it is doing or what you want it to do .

 

been doing some jumps and the shocks arent holdin at the track...

 

Here is a link for adjusting shock adjusting

If you do a lot of jumping I would highly recommend changing the fronts , the rear once adjusted should be fine .
I do a lot of jumping and have never had a prob with the rear ( I weigh 165 ) , it was the fronts that would always bottom out , even on the hardest setting.

 

I have the same problem with the fronts bottoming out. What brand did you buy?

 

Works triple rates with out rezzies $ 331.00 through rocky mtn. night and day diff. I can now double the height and distance off a jump I was bottoming out the front with the stockers.
