Dang, those are some pretty big changes, Kyle! Looks like you are progressing well. I don't envy you having to put graphics on. I just finished up mine. It's not horrible, but I wouldn't want to do it very often! LOL. I really like the JD a-arms also; they look sharp. Another option for the rear may be this: Drew Cox @ Maul Tech is wrapping up the loose ends of the 450R swingarm, new linkage, and long travel shock project. They will offer the new long travel linkage and the new shock for sale. The shock will be a custom length (just like the cr500 and no link shocks). I am waiting for him to finish with great anticipation. Just thought I would throw that out there. If more people put pressure on him, he might finish sooner.
Can't wait to see what the finished quad looks like! Great job so far.
