Has anyone done the switch? Which shock do I use? Length? What link? I think i will have to weld a mount for a linkage on the rear of the frame, is it still going to be legal to race?
My son and I are starting to build his new machine for next season and I have a stock 450 swinger and new in the box RPM sure would make it easier and probably a better ride than stubby stock.
Thanks in advance for the help
