Mistakes? Meh. I knew where you were going.
Another funny thing on the hydraulic lifters...
The Honda Nighthawk has them too. The bike requires almost no maintenance, runs as smooth as a sewing machine, and will run forever if you just change the oil. It's the most soulless machine I've ever ridden. Great for reliability but just nothing to draw you in. The REs are just the opposite, getting more reliable and lower maintenance all the time but still loads of character. As the local dealer described the update UCE bike, "They updated everything they should have and left the rest alone."
