Shock Spring rubbing on Head-Pipe

Was doing some much needed maintenance this weekend and noticed that my shock spring has been rubbing on the head pipe right before it connects to the silencer. This is not the stock spring.(Eibach springs) Just wondering if anyone else has had the same problem. It isn't rubbing unless the shock is about midway through its stroke and there doesn't appear to be anything bent that I can see.

Mostly likely the collar that joins the mid-pipe to the headpipe is rotated to the point where the end of the bold is rubbing on the spring. Rotate it so that the end is nowhere near the spring. Mine is mounted so the bolt is on top and seems to provide plenty of clearance w/o having the bolt exposed to your boot/leg.

Be careful! My pipe was puncture due to this problem.

Check your subframe to make sure that it's not bent to the left..pulling the pipe closer to the spings.....

If your pipe is damaged, it's about $150 to replace

It happened on my '02 and my subframe was not even bent. I shimmed the silencer to make it sit farther away from the spring. Try putting washers in between the exhaust mount and subframe mount to pull the pipe towards the frame and away from your shock.

Thanks for the info guys. I think I'll try Antmans advice and shim it.

Antman gave you the good scoop on this one.

I had the same prob, and utilized the same fix. I tried prying the pipe over with some clever methods, but adding a thick washer between the silencer and subframe had much more effect. If you don't, you'll rub a hole in your pipe.

Rage on! :)


You suck! You should have SHARED this information BEFORE my pipe was punctured! :) (just kidding)

If I had known about this, my pipe would still be alive today.

      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?
