Anyone sick of their chain hitting the frame?

Man I am tired of the chain woes I am having with this bike. The funny thing is that at the supercross over the weekend I could hear the chains hitting the frame on a bunch of the guys on the track. Same thing riding at Elsinore on Friday. Each 450 that went by you could here the rattle.

I know people are going to say this and that about "what chain", "proper adjustment" etc. but this is a known problem with these bikes. I need to make something to end my madness.

Of course it's a problem......

w/o an o-ring chain and proper adjustment anyway.

Thanks for the tip.

I set my chain slack at 3/4" at it's tightest point and my chain doesn't hit the frame. I also run a DID X-ring chain.

If it bothers you that much take the swingarm off and tap a hole in the frame and bolt a piece of teflon or nylon to the frame.

Thanks. I was thinking about doing something like that. I was hoping someone had already made something. I just don't get how Honda let a problem like this go out the door.

I'm glad someone posted this. I thought it was just me. I put on an Oring chain and then the chain groved it's position into the chain guide and was clackiticlack again. I adjusted it again and no more noise.

It is annoying if it's out of adjustment.

here are the pics again , still works great :)




I can see your frame is still getting chewed. I like the looks of your guard for the mud flap side.

I've gone with an O-ring chain too on my 02' and now my 03' and no more problems.

I used to have the same problem, on the 450 you have to run the chain tighter then other bikes. I cannot remember, but I read it somewhere on the internet. The rear suspension is the opposite of other bikes, the chain actually loosens when the suspension is compressed. If you keep your chain adjusted properly, you will not have any problems. :)

      I need recommendations on Honda dealers with good Mechanics in Western Washington. I am in Puyallup but will drive for peace of mind. I have never had a dealer do major work on any of my dirt bikes. But long story short I am on a 15 CRF450R and it needs the 5th gear recall done. Any and all info is much appreciated!

      I have a 2005 CRF450R with a Trail Tech fan kit installed. I need a little bit larger tank and would like to know if anyone has an aftermarket tank that fits with the fan kit.
      I dont need a monster 4 gallon, just maybe a 2.4 or 2.7 from IMS would do fine.  I talked with both the tank vendor and Trail Tech and neither could give me any answers.
      Thanks guys.

      So I emailed Factory Connection today to see what spring rate I need for the rear as I’m about 6’2” 220 lbs without gear. I also asked for a baseline front fork PSI to start at. This is what I received:
      The spring series we made for your bike is limited when it comes to larger/stiffer rates.  
      The spring rate you need is 5.9/6.0 range. We don’t sell that over the counter as it requires special installation process.  So we can’t sell the spring “over the counter”.  It would have to be installed at our shop.  
      Fork PSI I would recommend:
      Inner 160 psi
      Outer 11 psi
      Balance 160 psi
      Are they blowing smoke up my ass? What kind of ‘special installation’ could a spring take? I’ve changed and removed them before but not on a 16’ CRF before.
      Also, aren’t those psi settings for the Kawasaki KYB? I don’t think the psf2 have inner/outer/balance do they? Maybe he was having a bad day...or maybe I’m an idiot. FC’s website list there spring as ALS-0059. Can I not just order this spring and install it to set my sag correctly? Help?
