do you have to change the top link's length to achive the birdcage rotation? Or do you have to index it forward?

18zero18, How does the spring and shock mount to the LR on a 4 bar LR, swingarm RR set-up? Are they connected to the birdcage or the axle housing? How does the spring add weight to the LR when the birdcage rotates CCW?

if im correct the spring mounts on the rear side with the shock in front side on the LR..mounted on a bracket that floates on the axle housing??? the same bracket that holds the 2 links?? kinda like the one i have now thats welded on but it also has a mount on top for the top link?? why the swingarm (Z-link)RR? more weight on the spring? or is it cause of roll steer?

mod racer is correct the shock is on the front with the the spring in the back both mount to the birdcage. scott, the top bar is longer then the bottom so when you pick up the thottle the chassis lifts when that happens the birdcage is forced ccw. it does not really add weight to the left rear its like this the birdcage rotates ccw if the spring is in front it is being unloaded but if it is behind the axle then it is being compressed thus keeping the left rear driving down. hope this helps
