While removing the Carb from my 07'WR450F, I figured what better time to do some preventative maintenance on my Swingarm, and Linkage. I removed the swingarm, shock, and linkage to grease the bearings. While greasing one of my linkage bearings, most of the roller needles fell out onto my work bench. I tried to put them back in one at a time, but everytime I tried to insert the roller back in it would push them back out. It's now back together, greased, but one bearing is missing probably 12 or more roller needles. Isn't there supposed to be something holding these in place aside from the roller? Is it worth while for me to try it again, or is it just toast? If they're toast then is there a better linkage kit out there that may not cause such a headache?
