Great minds think alike!
Yep - output shaft needs to be watched as on anything with big suspension travel - people run the chain too tight - you want at least 40mm of free play when you're sat on it. Big job if it's buggered
Fuel pump can be changed for a Facet type pretty easily to be on the safe side - a cost effective and sensible upgrade
Massive mileage not an issue, the 52degree twin is in such a lazy state of tune - delivers power in a completely linear way, seems to be no torque curve, same grunt whatever the revs (as much grunt as 55 horses can offer!)
Mac - I expected a far greater grade of abuse, perhaps I should of gone for a Multistrada? Shall pop down your way and see if I can re-enact the famous "railway lines episode"
