yeah it was a shot foy you danny who obviously just changes his oil and rides his bike on the same trails everyweekend and sits in the garage talking about good he is at taking corners and doing wheelies.........thats a shot smart one. No advice for Danny.

I did make the geek list

They don't ever mention what the material is. It is most likely Tungsten Carbide.

The only reference to it is this:



"One other significant change concerns a new material that has been incorporated into the seat of the intake valves. This new material features a finer grain structure in the metal, a change that will improve valve wear and reduce intervals for servicing."

so you don't have to reshim all the time

Nobody on this site has had to re-shim "all the time" ,including those with 05's. Nobody on this site ever had to re-shim their valves twice that I know of either. To add to the news flash,the majority of us have NEVER had to "shim all the time",but how about this,we've never had to shim at all.
However,there have been a many who measured the clearances incorrectly and shimmed when they didn't have to.
These bikes can take a whole lot of high rpm work,and there's no need to be "careful" with them to "save the valves".
Did you read the Dirt Rider 200 hour tear down,which needed ONE valve adjusted in all that time ? And they didn't

I don't ride like a either

. either, they rode a 24 hour race,among other things.
I was under the impression that the 450X valve seat material has never changed,that actually the 450X valve seat material is what 06 and later 450R and 250X/ 250R's have now. Regardless,where are the stories about 450X owners telling us all about how they needed to replace their valve seats ?
How about Dirt Bike,they took a bone stock and brand new 450X and ran Baja with it,and all valves were perfect after the race.
The 450X is a great bike,and it gets tiresome answering to myths and urban legends that don't exist.
Each and every modern thumper will need valve work down the road. The 450X has proven to be one that will need it way,way down that road if you take care of it.
Taking care of it doesn't mean checking and shimming the valves constantly,it means clean oil,air filters and common sense. Doug

this is something the dealer or sales man will tell you owning the 450x. Well here it is. I replace oil and trans oil after every ride plus cycle through 4 clean air filters. I have ridden the baja a handful of times and my valves need to be shimmed twice a year. Matter fact I am almost up for a rebuil of the valve system. So you guys think you know a lot about this valve issue but you don't. You are the crf 450X owners that ride about once a month. Well I have been to baja many times. So let dirt/Ride magazine tell you what ya want to think. they probably didn't include that they prob wouldn't ride the same bike again in mexico after a major motor rebuild. So don't write about the valves like your a pro.

Want to share a little bit about yourself and your travels? How many hours on your machine? What year? What is your riding style? Do you feel that you represent the average off road rider?

Just so we can get a true picture of what your pro opinion is based on.

Oh, yeah, you are the guy with the 05 that had to shim after 10 hrs. A lot of us have way more than that, so what makes you the pro? Looks like you are an exception, to me. Not a good one at that.

Oh that's funny and that figures. There's a good post on here about how not make that mistake. Here you go,now look carefully,and remember,cam lobes to the rear,and line up the two cute little arrows on the cam tower and the cam sprocket !

Darn, it sure is easy to use that wrong mark when setting TDC, isn't it ? Darn Hondas. There,there. It's okay,we all screw up.

Well I have been to baja many times

For what ? You mean the race,or one of them ? What's your name,number and class, pro boy ? Oh,is the BS light ever glowing.Because pal, anyone who has raced there wouldn't call it "been to Baja",because people go to Baja for a lot of things.
So don't write about the valves like your a pro.
Who exactly are you to tell any of us anything in such a rude manner? We're sharing what we know with each other and to dispel myths.If you ride as hard and fast and as much as you say, you've gotten pretty good service out of the bike if you ask me.

You are the crf 450X owners that ride about once a month.

How would you know ? Let's see, right now it's 19 degrees out and snowing. Okay with you if I don't ride? Do you have a job ? A family ? ED causing you to lash out ? We get our data from hour meters, odometers, and educated estimates.
There are a whole lot of very talented and educated people on this site,and we don't appreciate your taking potshots that you can't back up.

So let dirt/Ride magazine tell you what ya want to think

. It's Dirt Rider,Johnny Campbell. While I don't agree with everything they print,they don't lie,they have no reason to. If you read it,they said that motor was still in great shape. So even if you don't believe "dirt/Ride", I'll bet the folks on their staff ran that bike pretty hard. Didn't you read that they ran the 24 hour race ? Were you there ,leading your class until the top end fragged or something else dire ?
We look forward anxiously to your next bit of sage wisdom. After all,you've been to Baja, right ? Doug

they probably didn't include that they prob wouldn't ride the same bike again in mexico after a major motor rebuild.

Why do you think this and how do you define major motor rebuild?

We are getting a bit TT-ish around here boys.

I admit, his was a very TT'ish statement. The same type of dribble that goes on over there all the time.

Roady, I don't personally know you, but I got the impression from DD and others that you are an accomplished rider and good at maintenance. Your 3000 miles before incident is more what I expect. In fact, I will be very happy to get that considering the performance these bikes have. I will change to Kibblewhites or whatever, because my version of this outstanding RACE bike doesn't need to shed a few ounces in the form of titanium valves.

That race bike statement is a fact that a lot of CRF owners don't think about too much. It's a great PLAY bike, but it is bred as a RACE bike.

I hope to change that not having ridden together soon Joe. I couldn't agree with you more re: having to replace the top end after 3,000 miles and 2 years of use being an acceptable (but still un happy) price of admission. I also resemble the once a month rider statement at times, much to my displeasure ... realities of my world.

I definitely was not aiming anything at you Joe, just an observation. I am sure a search of my past posts would find me reacting to what I consider BS or confrontational on occasion.

I think part of the discussion was deleted also since I see a quote in one post without ever having seen the post anywhere.

You are not going to get a lot of help on here with your poor attitude! Take your crap over to TT and you might get an idiot to agree with you on your valve issues. It will probably be a Yammi rider in the wrong forum though. Good luck.

I knew you weren't shooting at me, Roady. You were quite correct in your observation, though. I really do try not to fence with idiots, but I failed this time for sure. Oh well...

Looking forward to riding with you too. Come on warm weather!
