Pre war Burman clutch
My Burman clutch will not operate satisfactorily in as much as first gear engagement from a standing start is dreadful., that is to say it produces a horrible grating noise before engagement I have checked all the things which I think are obvious including:
There is approx 1/8” lift on the clutch push rod
Cable. pivots & push rod are lubricated
Plates lift squarely
There are no burrs or indentations either on the ears of the plates or the basket
I replaced the original perforated plate / cork insert arrangement.
I changed the oil from 20/50 to 10/30
When in gear with engine stopped the clutch can be pulled in and the bike pushed forward, i.e. the clutch appears to work ok.
I am aware that if left standing the clutch will stick and needs to be freed up.
I am also used to paddling bikes forward and engaging gear to prevent grating.
The problem is that this clutch appears to defy logic and I really do have to sort it one way or another as the grating is just shocking. I am aware that Conways do a Japanese clutch as a kit but surely these clutches used to work?
Can anyone provide any informed comment leading to a solution?
