I did my first top end since I bought it and the power valve has no bearings on one side. Has anyone seen this? Pic attached. You can see the bearing on the one side. On the other side there's a bushing? No bearings. I don?t have a legit manual. I have a later manual showing two bearings on that side but I don't know what was supposed to be on this particular bike.
