Been there, done that, NOT a fan of sight glasses for the oil, on any bike. Simplecureforthe over fill is a few inches of surgical tubing and a turkey baster. Looks funny, works great.

If you like the factory tools, fine, keep them. But, you're still going to need a toolbag with sockets, wrenches and hex keys. Ever try to pull the seat with the stock tools? You'll definitely appreciate a socket, extension and ratchet.  You should also carry money for a pay phone in your tool bag. Cellphones still don't work everywhere. I don't even own a cellphone anymore. A year's worth of bills for a phone that rarely got used? Cellphones are evil.

Also, join B.A.M. or a related orginization. Bro's club is a good one, if they haven't gone back to HD only. Both offer a member aid list of riders across the USA who'll help if you break-down, get in a wreck, etc. There's bound to be a European version of some sort. Call the club, they send someone out to help you. At little or no charge for the club or the services.
