I noticed my shock spring almost touching my exhaust on 06 525exc. I pushed on the spring with my hand and the swing arm moved over 1/8"! I know that cant be right but looking at the schematic view of the bearing layout, wth holds the swing arm from moving side to side? I see the bearings, sleeve, seals and some small cap type things that go on the end of the sleeves (outer end) but what actually keep the swing arm from sliding side to side inside the bearings? Looking at mine there appears to be some sort of spacer on the left side between the swing arm and frame beam but on the right, it just looks like the sleeve mates up to the frame? Am I missing something on one side? Got this bike in a trade. So far the motor has been rebuilt at cannon racecraft in OKC, forks rebuilt, and its super clean and runs great other than it needed valve lash set. So it seems odd that an important part like a swing arm spacer would be mia. Any ideas?
