Revisting the forward shock movement for a bit:
When the first Elsinores came out they had standard mounting for the shocks. We moved the top mounting forward to get a few more inches and this seemed to work OK with the stock forks. But you know how if a little is good a lot is better? We then moved the bottom mount (on the swingarm) up as well, and this gave us about 10.5 inches in the rear, IIRC and a wicked rake angle in the front.
Lots of trial and error finding a spring that would work with the increased leverage. At first, we would just install a stronger spring and did nothing with the damping. We had no clue. This is when Fox Shox (you know, the guys with the clothing line) came in.
In those days, if you could find a welder, you had a "works bike"!
This is also when the the problems with chain tensioning began.
