Martin, you may be well surprised how easy it is if like Hagon it's simply knowing the knack of it. Not having examined the 440's of course I can't say but with mine screwing the preload to zilch and not being under compression is half the battle.
Btw guys, thanks for you words of encouragement. I felt like a bit of a dope being as long as it was but I did believe the points needed to be put out there for several reasons but predominantly to stress the safety factor and who knows, some of you guys may not have appreciated the true value of your 440's yet. I'm not by any stretch trying to make anyone feel like dopes or anything but we all deserve the best ride we can get on our bikes, and when it's finally dialled in it's just superb but more importantly safer.
