It's a yfz thread, so I just had to subscribe. If your worried about jetting, once you have it figured out it is not bad at all, and honestly I like the ability to really fine tune it. I had the bike dyno'ed last spring with the new motor, once I got everything set I just adjust the main jet up and down with temp, and the bike always fires instantly in any weather. I am putting a wide band on it this winter which has me excited to be able to really dial it right in.
If you are looking for a good fire it up and go bike the r is definitly a nice choice. If you have any intentions of modding it I would look more into a carved model.
