Kawi's have plastic shoes on their camshaft tensioners as well (Part #12053A), but they are much longer than HD's.
I have a 2013 Voyager, with a few mods but nothing spectacular. I also owned a Road King back when the TC 88's were first manufactured.
Honestly, it really depends on how much you like to tinker and polish. If you are "Car/Bike Guy" that likes to spend weekends doing things like adjusting your throttle settings, replacing your own clutch baskets and such the HD is a nice bike. In my personal opinion, the Venture is more of bike for those who don't like to tinker as much.
True story- I was at the Mazda dealership last week, buying the wife a new CX-5. After the deal was done, I talked to the finance guy (but really the "closer" lol) and asked him how much hold-back money Mazda was releasing for each car sold, now that they are no longer a part of Ford Motor. His answer surprised me. Basically, the dealership makes no money on the sales and the holdback money goes to the salesman. The dealerships these days make most their money off the Service Dept...since they control all the new computer coding.
If bikes are the same as cars now, I doubt HD's new motor is significantly better than the old Evos...otherwise they would lose money on servicing. The 1700 motor has been around for *years* with no major changes except for an outside fan on the rear jug. Just something to consider.
