Well yes, but I would say that 46 is really part of the speedo drive as it sits in a recess inside the drive to protect the monkey metal. Ron

Dave it's a strange thing that BSA fitted two spacer washers here and they are clearly shown in the parts list. But I have seen bikes fitted with two and also one. As it happens my WM20 is fitted with one 'extra thick' washer and my M20 special has the two as stated. So unless Les is selling the extra thick spacer washer, I'm not sure if he is right Ron

Thanks Ron,

Yes it does seem to be a bit confusing. I don't know what the thickness should be.
I don't have any Mic's to measure the thickness, but will be able to hopfully this week.

Dave, this old discussion has some good dimensions info and touches on the 1 or 2 washer topic.

Item 46 is very important as if that is left out the speedo drive can be deformed (as was done on one of my M20's at some point).

Got it. Thanks Ron.

Hi Ron,

Yes your dead right, it's a silly idea having 2 spacers instead of the one. I have 2 so shall see how it goes, when I get around to that job.
I got one of the inside speedo washers from Les last year, mine was missing
