YZ2 front shock mystery
I have a mini-mystery going on with my DT, where i need to have front shock attached to the outer most hole on shock tower and inner most hole on the suspension arm, in order to get some sort of decent working of the shock. Any other combination sees the shock have a dead effect where it has hardly any rebound. Some might say it's the shock, but I have put the shocks from my CA - which work absolutely fine on the CA - onto the DT, and the same result happens, a shock that is acting dead. I've rebuilt the DT shock from scratch too, with new pistons/o-rings/oil etc, and that hasn't solved it. The other point to note is that if i tighten up the nut holding the shock to the tower i lose around 1.5mm of rebound, so that is not even as tight as you would normally expect to be able to have it. Any thoughts on what might be going on? thanks

Hi,
Is the car the same with the CA shock on the DT and the DT shocks on the DT? Have you tried the DT shocks on the CA? Does the arm move freely with no shock on it? Is there any chance the spring cup is fouling on the arm? Trapping and causing friction. MiCk B. :-)

Yeah. With the shock off the car it operates perfectly normal. It’s as if the car itself has an issue and doesn’t matter what shock is put on it. And to make doubly sure the shock isn’t getting fouled by the tower I put a small spacer on the screws the top of the shocks fit onto, just to give it a few more mils of clearance.
And the arms move freely with no shocks on too. Last edited by xmyass; 12-02-2019 at 11:01 PM. Reason: Update |

Do you have to pull down on the arm to get the shock to fully extend?

it sounds like you are over-tightening the nut holding the top of the shock, which is compressing the plastic shock perch into the shock cap.
Swap the plastic shock perches for the alloy ones, or replace the plastic perches and don't over tighten - ensure the shock moves freely on then.

Are the screws in perfectly straight?
If they are in cockeyed it can things bind up depending on the design of the mounts top and bottom. |
