I just want to check if it been converted to unleaded, if not that'll probably be first thing on the list.

Um. I wouldn't worry about it too much.
Experience of many riders is that a higher mileage engine will have case hardened it's valves and seats beyond the point where unleaded fuel will worry it too much.
Just run it (maybe with a lead additive - I use Castrol 'cos I can stash the handy bottle somewhere on the bike).
Keep an eye on your tappet clearances. Easy on an R100. If they're closing up big time, only then consider having work done.
It's a better option than chucking your heads at some expensive head modifier for no good reason.
I've run 70's Laverdas for years. Converted one - wish I hadn't. The others are still charging along happily (touch wood).
HTH and saves you some money.

PS. Castrol Valvemaster. About a tenner a bottle You don't need much per tank & so lasts for ages. Bottle design means you can stash / carry it leak free.[/quote]
Thanks for the advice. I came to the same conclusion after some googling and talking to the guy at Motorworks.
Hate to say it, but I'm too young to have come across leaded petrol, so I didn't know what was involved.
Going on Friday for a look at the bike, hope its as nice in real life as the photo!
Not sure what to expect in terms of the ride, but I liked my 1150 boxer over the 1200 because it was less smooth and more rough, how I expected a boxer to be. hope the r100 is more of the same.
