Ok so I recently installed new springs (for my weight) on my 07 WR450. Now since having done that a month or so ago, I feel like I've broke in the rear spring and I want to get the sag set right. I'm used to doing this on KTM's and working on the WR is a major PITA so I'm looking for the easiest way to accomplish this. First however, I need to know where my rider sag numbers really need to be. The manual states between 90-100mm but I've read here between 100-110mm. I've also read in much more simplistic terms, it needs to be at or very close to 4" and around 1" static. So which is best? And what's the limit for preload on that spring? Then, what's the easiest way to turn those fing collars on this bike. There is no way to get the proper tool in there to crank on those without pulling the whole back end down. So the only option is to pound on the collars with a screwdriver but that is going to trash them. What's the best way you that have worked on these bikes have found to do this?
