Wheelie question

If the OP moves the IC up and back he will almost certainly have to make the shock stiffer in rebound to keep the tire from bouncing back after the hit.

YR, buy moving up a hole, would'nt that be triangulating the bars more, therefore giving more leverage for lift??[/QUOTE]


Yes it will give the bar more leverage. It also speeds up how fast and how hard the chassis hits the tire. An IC of say 34 inches out and 8 inches up (I'm guessing on my numbers because I haven't run a ladder bar since 1984) may be the middle hole. So, if you move to the next hole up you are still about 34 inches out but you will be about 2 inches higher. With the bar running downhill to the back you are giving it more leverage than it had before, and it makes the bars hit the tire harder. If it does, you have to possibly add 2 maybe 3 clicks of rebound damping in the rear shocks. If you hit the tire hard enough, it will try to bounce back up into the wheel well. That's why a DA shock is so important. You can make the shock extend very quickly and hit the tire. A and then you can stiffen the rebound so the tire doesn't try to bounce.

DA shocks are the single most important tuning tool you have. If you have single adjustable shocks, you are stuck with the engineers idea of what compression dampening works with what rebound dampening. DA shocks give you the extra tune-ability to greatly change shock behavior in one direction without doing a thing to the other direction.
