i have a question, the little ball bearings under the clutch plate around the clutch's rotating disc on the inside(you can barley see them in there) is it ok to grease these as they are moving parts. I did do this in my older engine twice and noticed significant clutch response and it was very smooth. though the second time i did put too much grease and noticed clutch slipping after about 20 kms. I haven't done this with my new engine yet but want too unless advised otherwise.
