Well for this first seingarm im building im going to keep the shock moumt int exact same location and use all oem linkage. Im almost done building this one so the next ome i build i want to figure a way to make it no link. It may require me to move the shock mount tabs on the frame some to get the right leverage ratio. I have seen lots of threads on the everything2stroke page where ppl are cutting the stock swingarm and welding in blocks for support to shorten or lengthen the swingarm. Ive seen all the way down to -4 seinger for tt/ice racing
