The deal is the simpler the machine the easier it is to work on. "newer" technology is great but can be polarizing to work on, shim in bucket valves are not as easy as screw and nut. Water cooled has radiators extra hoses water pump it clutters things. I'm only 28 but I just like the look of air/oil cooled engines (not a harley fan). Water cooled are covered with fairings and are "industrial" lumps that are efficient but are hidden away. You think that the technology we have today and modern metallurgy the air oil cooled should still be a viable option I guess. obviously you guys see that i have a vfr, its a great bike but i loath doing a valve inspection on this thing, and taking it to a dealer will at least cost me $500 granted it only needs to be done every 20k but that's every two and years for me!
