Vox, I am talking the chrome outer cover that comes off to attach clutch cable, and adjust freeplay.. not affected by the springs.. the one folks like to replace with a finned one.
I remeber that part, weighed about 30 lbs
I was working for Leslie Griffith Motors in 78, it was on F2 I had to do a cam cover change on (bike had fallen onto edge of curb and cracked right side, insurance was paying)
Didn't some of them have a thick rubber buffer inside as well?
It was to reduce noise as far as I can remember but I think they were really for German market (remember the proposed noise legislation in Germany?)
BMW boxer couldn't meet db noise limits at 30mph with a dead engine
Sometimes I'm amazed at the crap I remember (conditional learning
)
