ok, maybe not a technical question, but what exactly is the purpose of all these wee 'hockey pucks' I keep finding amongst the engine cooling fins ?

I'm guessing it had something to do with resonant frequencies. Fin flap, in other words.and God said, "Let there be air compressors!"

I can't keep the f's going, but the reason for the FFFF's is noise. Specifically, the noise regs for bikes were tightening up in the early 80's and the ringing noise you get from aircooled engine fins was a noticeable contributor to overall noise levels. Hence, FFFF's to stop the ringing noise. Lots of the later aircooled bikes (all brands) had some version of them.

Life is a balancing act, enjoy every day, "later" will come sooner than you think. Denying yourself joy now betting you will have health and money to enjoy life later is a bad bet.
