What causes rear-end wobble?

What causes the rear-end to bounce side to side in nasty whoops? like the kind of shit that eventually turns your ass sideways doing 30?

Cranking up the rebound helped me stop that.

^^^ that helps, ( you mean slow down the rebound), but how much does the rear unload after landing? should be next to none.

Put your arse further back. To forward and it allows the rear to swap sides.

LMAO Bob!

I never attack whoops in a forward position. still gets squirrely sometimes, makes me nervous.....I always stay on the seat/pegs and grab more throttle......been lucky so far.

I think Bob's been hit by the Devil of Lust.

It happens to the best of us.

How long has it been since the shock was rebuilt?

From the factoryconnection site in the set up tips section. Lots of good info there.


BACK END KICKS SIDE TO SIDE:
SHOCK - Generally caused by too much compression damping on most types of terrain. Too much compression damping on square edge terrain can cause the back end to kick side to side and/or lose traction. Also, too much rebound damping will cause this because the back end is held down in a stiffer area of the travel which in turn makes it too stiff for the bumps it’s hitting (packing).

BACK END KICKS STRAIGHT UP:
SHOCK - Generally caused by too little or not enough rebound damping. Slow rebound damping 1-2 clicks. Note: In some applications rebound affects compression damping. Adding too much rebound stiffens the shock damping, decreasing rebound too much softens the shock damping

Well, the 250 shock is blown. But it rarely, and I mean RARELY happens on that bike. The 450/500 is another story. I plan on spending some serious time tuning the suspension on that bike, and was looking for what to fiddle with. :cool:

The extra power will amplify suspension issues.

The 500, the suspension is tight, just not "clickered" for my personal tastes yet. A blown base gasket cut my riding short.

How much over 100 hours is "tight"? Just cause it doesn't leak doesn't mean it's tight.

the clickers have a very noticeable effect on handling all the way around, and nothing leaks. Beyond that, its just a guess.

Reset your shock to stock settings. Then tune ONE setting at time
Comp: 2 clicks and ride it Rebound: 2 clicks and ride it Hi Speed Comp
: 1/8 turns max and ride it Start from scratch so you can see if its
JUST rebound. Never adjust more than one setting at a time. If you
dont like it you wont know why. If your oil is trashed your wasting
time. Itll need to be serviced. Spend it if need be it might save your ASS!

I'd imagine spring rate plays a role in there somewhere.
