The only air-head I had was not short of character, I have to say! An R100 RS with 4 valve Krauser heads, absurd compression ratio, hard-to-get sparking plugs, a capacity to eat clutches for breakfast, plus subsequently spitting most of a lobe off the camshaft, it was at least as much 'fun' as any Brit bike for the 50K miles I kept it! Not to mention that darn detent spring in the 'box. But when she went, she WENT, extremely fast for a twin of its day.
However, a K100 RS fulfilled the need for incident-free reliable and less-exciting wheels for my then-daily commute of 80+ miles . . .
