I don't know if they'll import them to Canada or not, but the new "retro" V-7 Moto Guzzi is apparently a good ride for shorter riders, and it has the air-cooled V-twin MG simplicity and shaft drive and fairly low center of gravity. Only a little more oomph than your LRB and OK gas mileage too.. I am also thinking that I may never buy another chain drive bike again, unless I somehow get interested in dirt riding again (but that seems more of a younger person's thing). Belt drive would be OK with me too.
Many of the Japanese liquid cooled V-twin cruisers have the hydraulic, no-touch valve lash adjusters. It is hard to get hydraulic valve lash adjusters to work well in engines that can spin much past 7000 RPM, but most V-twin cruisers of both liquid or air-cooled persuasion will never see that. And of course, the Milwaukee-powered machines, as well as the Polaris-powered Victory bikes. Honda did have a very nice air cooled 700cc 4 cylinder model in the 80s -early 90s - a CB700 SC here in the states, and it may also have been sold as a 750 Nighthawk S or SC in Canada (but beware there were other 750CC Hondas with earlier similar styling that were shim under bucket, older style engines) that had automatic hydraulic valve lash adjusters and it had a redline of close to 10K. It was apparently a pretty bulletproof engine and bike, but like a number of Hondas its styling was too plain vanilla for mass bike-market appeal. A friend of mine owned one, and it was a nice bike, though it was a bit of a semi "standard, semi-cruiser style machine - it did most things quite well but wasn't controversial looking. I think that there are other bikes out there with hydraulic valve lash adjusters, too, but they aren't nearly so common as they are in the V-twin cruiser market.
I like my 1998 Kawasaki Concours because it surprisingly has screw-type adjusters for its 16 valves - it was built the same way from 1986 - 2006. It takes me hours longer to adjust the valves on it (much stuff has to come off) then an airhead or a Moto-Guzzi would, but at least I don't need to buy boxes of specialized shims in the process. I can deal with having a complex computer, but I like having relatively simple vehicles that I can work on without paying someone else $80/hour to learn on. The new version of the Concours look very stylish and have incredible amounts of power and safety features, but are even more complicated than any modern K bike you can imagine - as much as I like the looks of them, I don't think I'd ever buy one, as the only prayer one has to tune the thing up is to take it to a dealer periodically for $800 tuneups..
