I plan to replace the shock spring on my 04 WR450 tonight. Any tips on how to do this with a minimal amount of disassembly? The manual tells you to pretty much disassemble the whole back end of the bike. It looks to me like I need to disconnect the lower part of the subframe, air intake off of the carb and then swing the subframe up out of the way. Then remove the top and bottom bolts on the shock, and maybe the bottom link. I'm also guessing that before I unbolt the shock that I should loosen up the existing spring...removing all tension/preload on it. Can I replace the spring (going stiffer) without having an actual spring compressor? Any/all pointers would be appreciated!! Also, what's the grease of choice for the suspension bearings? The manual says a lithium based (and I believe, waterproof) grease.
