Hi all,
Up until today I had always thought that all the swinging arm engines required the circular spacer plate between the primary drive crank case half, and the inner primary drive case half.
However, a friend is putting together a bike, and says his research tells him that some of the S/A models did not use the plate.
Can anyone confirm this please.
If it is true, which model(s) did not use the plate?
Thanks,
Richard
