Hmmm, 

         I just figured I'd write.  I was on the waiting list forever it seemed like for the '06 YZ450.  It was worth the wait.   I had my doubts, though.  Honda has been making an awesome product for the past few years.  This is my first 4-stroke, even though I've ridden them all.  This has to be the nicest one I've ridden so far.  I just came off of an '03 YZ250, and this bike is so much more friendly.  I remember some of my buddies remarking about how I'm making it around the track faster than before.  Actually it's just gotten harder to keep up with this new bike.  It's awesome.  I'm kinda like the other guy who posted, I case jumps alot.  The first thing I noticed was the suspension really resists the bottoming, and all around it feels good.  It'll definitely make you more confident while you're out there.  Yeah, I'd definitely recommend this bike for anyone out there, regardless of skill level.  I have some questions about the motor, though.  How important is it that you religiously check the valvetrain?  I ride it pretty hard, although I'm nowhere near some of the guys I've seen.  Probably about 70 percent or so.  I did check the valve lash after the break-in, and I made sure I was careful to follow the manual with regards to that.  The first three rides I changed the oil and filter each time.  Now I think I'm gonna do it every two, maybe three rides if they're short.  Does anyone have any thoughts on this?
