the first problem is the lack of rake. It would be nice to have about 10* of rake to the frontend. And the a-arms are mounted fairly far apart. bring the a-arms in closer to center and give it 10* of rake and it would be OK. but then you still have to do battle with the rear suspension cuz of the short ass shock it uses. On any legit LT frame, the shock mount is right underneath the seat, giving you a nice long shock to work. I've heard the elka linkage works good, but its just a band-aid for a flawed design IMO. The shock should be higher in the frame, and if you did that you could go no-link, but then you lose the rising rate that the linkage gives.
As for the laeger t-pin front-end you are still dealing with a front-end that has very little rake and the a-arms are mounted far apart. Mount the a-arms closer together, then make the arms longer to make up for moving the mounts in would give it more travel. Adding rake would be the tricky part, cuz you would prolly have to modify the steering.
So to do it 100% right, build a frame to except the a long shock that mounts high in the frame and a CR500 link for the rear suspension, and the front end would have 250R geometry. With all of the time and effort that would take I would just buy a sundahl or a lonestar. I don't think leager makes frames for the banshee anymore.
