The flywheel is huge, once it got going the odd squirt on the throttle kept it purring along nicely. Yes, designed for outfits and touring. As I remember, very low comp at around 6.9:1 or something like that. I only sold it (early '90s) because I owed my ol' dad some money - been trying to locate it with a view to buying it back ever since (Reg 566 RE). I only did around 20,000 miles on it in about 5 years, as I had other bikes and was a despatch rider for a while.
The only real issue I had was losing a cover on both carbs (main jet?) - still managed to run though. Unfortunately, when I sold it, it was starting to smoke a bit. The reason, some inept mechanic set the valve clearances too tight which let to a bent pushrod and some valve damage (I don't have much luck with the 'professionals').
Other than that, faultless.
