Are pre mid-1962 R69Ss that unreliable? They don't have the reinforced cylinders, newer pistons with shorter wrist pins, vented rear drive case, crackshaft vibration damper, etc., etc. (I've been reading Ian Falloon's book on Boxers), but are the R69Ss after mid 1962 that much better?
Any informed opinons are welcome.
