nicky: i have a few problems with that vid. if that boy said "basically" one more time i was going to put my fist thru my monitor. my God. other problem is that while i commend him for his "McGyver-ness"...his method leaves a hell of alot to be desired. in lieu of buying/borrowing the Jim's or Motion-Pro tool.....see the below vid. this is the simplest and most ingenius way of doing the buell/sportster compression method in lieu of buying the actual tool. works like a charm and the vid is much better than me trying to explain all this. i know you're in the netherlands but these basic pieces required should be readily available there. hope that helps.
