I am doing a belt and roller change on my 2005 ET4 150 and noticed that when pushed inwards (towards the rear wheel) and spun, the shaft that the clutch sits on creates a grinding noise. When it is not pushed in and spun it sounds fine. Is this normal, or do I have a gearbox/final drive issue? I have a video of the issue but it looks like I can't upload videos to the forum - if there's a way to add videos to posts please let me know! Thanks
