Check the Honda forum and you may notice that their valve troubles seem to have ended at the '06 model year. 4 years late, but apparently corrected, nevertheless.

the honda is a great bike but the unicam is just not as good as the others 03-04-05-06-07-08---------------the first thing honda owners should do is buy kibble white valves,the yamaha a pipe.I will take the pipe.ive been the other way.all i do in my free time is ride and talk to people at the track and most would agree if you love hondas you will try to deny it:mad: but deep down your hating getting your valves checked every two months:cry:

I have both 07 and 08 yz450f both bikes have full pro-action front and rear the 07 has the 24mm off set clamps, the only diffrence is the 08 has sub tanks on the forks . the 08 has more power an is smoother puttin it to the ground . the 08 turn s way better than the 07 . sag is very ,very important on the set up of the 08 . just a small adjustment gose along way. the 08 turns so much better on flat ground and drop in ruts better an feel lighter in the air . i do wish it had a bit more bottom but that a simple fix . an both bikes are rock solid at high speed .


What are you running your sag at on the 08?

Once you go and check your valves on the Honda, and find they need to be re-shimmed? Its already to late!!!!!! Mite as well go ahead and have the valve job done because the valves are already beat up and dished and re-shimming will only last a couple rides. I have a Honda wall of shame in my garage, At least 20 sets of dished Honda valves from friends bikes. Compared to maybe one set each for Yz's and KX-F's, And those weren't even dished out.

No one thinks more of YZF's than I do. And before the new 450 came out my son, who does not like the older YZ450's at all, was resigned to the fact the he could either keep his 250F, or ride a YZ250, but I was not going to own a CRF.

But, let's be accurate. It's all too shamefully true that the CRF has a self made reputation as a valve eater, and also true that there is no excuse either for having it be like that in the first place, or for having taken 4 years to fix it. It isn't rocket science, and it has nothing to do with the YZ's 5 valve head, or Honda's UniCam. But it does seem from the record accumulated by the '06 an later models as if they finally got their head out of ...wherever it was, and put the whole messy thing behind them. The '06 and later CRF's just don't go through valves like they once did. You can't compare your '04 to the new ones. Sorry.

I have read an article where was said that Honda`s 2006 models had new valve seats. Maybe this is the reason.

heres a secret to riding 450s: if it feels like your arms will be ripped out, hit the weights. 5 years of weight lifting and conditioning have made it so im not afraid to throw any bike even 500s. heres the secret to hondas: take the titanium valves out and put ss ones in when you have problems(will outlast a yz if you get quality ones). after riding both bone stock the 08 yz450 feels somewhere between an xr and the crf. right about mid point between them. i prefer my 02 yz250 smoker over the 08 yz thumper

I still have half the adults on our team riding YZ450F's for 2008, so I am not abandoning camp here. I'll definitely report back honestly if any of the Honda's have reliability issues. I know one thing, the performance and handling is well worth the prospect of an increase in maintenance IMO. You can't put a price on the feeling of a perfect motocross bike right out of the box or a holeshot like this one I got at Pleasure Valley in the 30+ class. BTW - I'm the middle Honda CRF450R.

Good try - there are 6 YZ450F's in that race - 2 blue one's with the riders in blue helmets right behind us and the Yellow 2006 SE #11 is visible. I admitted earlier that I got holeshots all the time with my '07 YZ450F as well. It's all in the reaction time and full committment. BTW - those two blue Yami's beat me to the finish on the last lap - I'm an older 43 just having fun as long as I can.

We had a team school this summer with Gary Bailey and Ryan Smith at Lake Sugartree. He is fast and you will have a blast. Don't let his "Honda CRF450R" roost you too bad :-). BTW - at the MD State Championships at Budds Creek, Nick Evennou's Yamaha YZ450F's motor locked up on him landing from a jump during Saturday's race. He only got to race the 250F on Sunday. Keep safe and show the pics.
