    Looking for some stock CRF100 parts - any ideas?

    I found what I am looking for, thanks.
  2. Hello, I am looking to buy the following parts for my kid's 05 CRF100F: stock shock spring, stock fork springs, and a stock muffler/siencer. The person that I bought the bike from installed heavier BBR springs and louder end cap. I would like to take bike back to stock. Any ideas of where I could buy these parts or if anyone has thes parts they would like to sell, i wowuld be interested. Thanks. Jeff

    I have the heavier BBR shock spring that you are looking for. If you have the stock shock spring, I would be intersted in trading springs or buying your stock spring. Thanks. Jeff

    250R and 450R shock shaft - same or different

    FYI - I found out that the clevis's and rods are different between the 250 & 450. The threaded section of the rod/shaft that threads into the clevis are different lengths.
  6. Found out that the not only are the clevis's deifferent but the shock shaft rods are different as well (the threaded section that goes into the clevis are different lengths) so you defintely need to use the specific part for your year/model bike.

    Rebound adjuster is frozen

    Got it fixed - I just needed to clamp it tighter in the Racet Tech holding tool. The adjuster was stuck - a few turns with a pair of small pliers lossened it up and all is good. thanks fo ryour help.

    Blow drier heat or flame heat?

    Rebound adjuster is frozen

    I did set the adjuster to full soft before disassembly. I think the problem is what shockdoc suggested - the rebound needle is likley stuck. I tried to remove the reb/mv stem but I could get it to break free. I do have the proper/special clamps from Race Tech that install on your bench vice that are desigend to hold the damper rod. I cranked the vice very tight but the rod kept spinning in the clamps - fearing that I was going to damage the rod, I stopped and thought I would ask you guys. Two questions: 1) Are the threads on the reb/mv stem reverse threads or nomal threads? 2) Do I just crank down the vice as hard as I can and then wrench on the stem with everything I have or is there some type of trick or technique that I should use? Thanks.
  10. So I am wrapping up a fork oil/seal change and I go to set my rebound clicker and the clicker screw is frozen (won't turn either way), I ended up breaking the D shaped pin on the center bolt trying to turn the rebound screw. I bought a new center bolt and then fully dissassemble the fork to inspect everything. Everything looks good, the D shape in the rebound adjuster rod is not rounded off, etc. Right now I have the damper rod, D shape inner adjuster rod, and center bolt on my bench and I mock everything up, try to turn the rebound clicker screw and it is still frozen. The D shape adjuster rod is seated properly in the damper rod, the center bolt pin is seated in the adjuster rod, the lock nut is properly located but everything is still frozen up. It won't turn either way. I have also inserted a appropriate size flat blade screwdriver into the d shaped adjuster rod (in place of center bolt) to try to turn the adjuster rod but it won't budge. I don't want to force anything at this point. Why is everything locked up? What could the solution be? Thanks in advance for your help. The bike is a 2006 CRF250R.
  11. If the rod length is the only difference between the two can I use my 250 clevis by unscrewing it from my 250 rod and then screw the 250 clevis onto the 450 rod?

    250R and 450R shock shaft - same or different

    If the the clevis is the only difference and the rod is otherwise the same, can I use a 450 rod and screw it into my 250 clevis?
  13. Bike: 2006 CRF250R While servicing my shock (my first attempt at this - oil change +), I decided to fully disassemble and clean everything as well as learn about valving, etc. While removing the shock shaft nut, I tried to follow instructions to file off the peening but apparently I did not file enough and I ended up wrecking the nut and more importantly the threads on the shock shaft to the point of being not repairable so I will be needing a new shaft. My plan is to buy a complete used shock and use the shock shaft off of it. My question is: are the shock shafts the same on a 2006 CRF250R as a 2006 CRF450R. The reason I ask is that I found a brand new shock shaft on EBAY for a 2005-2008 CRF450R. I checked part #'s and for a 2005-2008 CRF250R the part # is: 52426-KRN-711 ($225) while the part # for a 2005-2008 CRF450R is 52426-MEN-711 ($188). Thanks for your help.

  15. The male pin on the centerbolt broke, the female d shaped rod hole was not rounded out. I think what happened was that when I put the rod into the damper I did not rotate the rod to seat it properly. Because it was not seated properly and it was still sticking out of the damper slightly(instead of being slightly recessed) after torquing the center bolt I effectively clamped the rod into a fixed position so it could not freely rotate so when I started to adjust (turn in) the rebound clicker it ended up snapping off. I have a ne centerbolt on order and will be careful when I reinstall. At least I hope this is what I did so it does not happen again.
