[QUOTE="timetraveller, post: 99454, member: 456"] If this shows up there should be a graph of the linear movement of the steering damper rod versus angle of the steering head. The straight line with the blue dots is the distance of one end of the damper rod from the damper body as the steering head is rotated. The lower curved line through the brown dots is the differences along the straight line to show up any non linearity of the movement against angle. Ideally these brown dots should be in between each of the upper blue dots. The line fitted to the brown dots is a third order polynomial, but you probably don't want to know that. Look at the lower curve and you will see that there is very little departure from linearity. Actual smallest value between the measurements is 9 and the largest, in the centre of the movement is 13. [ATTACH=full]23720[/ATTACH] Yes Vic, I did look at your Youtube video. It was from that that I thought that some of the parts might stick out and interfere with the legs of the Bramptons but you would have to assemble it to be sure that there is no problem.
