  1. Hey i have a 2006 crf450r and im doing a full engine rebuild on it. I had some issues getting the swing arm off the bike because the bearing races were seized to the pivot shaft and the inside of the swingarm/engine mount. I ended up cutting the shaft just to get the swing arm off so i could get the engine out of the frame. anyways, i got most of the shaft/bearings out and unseized but in the outside bearing races are stuck tight in the swing arm on both sides. ive spent hours heating them up red hot and trying to pound them out and theyve soaked in solvent and pb blaster for a few hours also and wont budge. not to mention that the swing arm hasnt walked away from this unharmed.. i was thinking that after buying the bearing kit for like 60 dollars and buying the new pivot shaft for like 16 dollars i would be a good portion of the way to just buying a swing arm off ebay that has new bearings in it and i could just bolt on. it would end up saving me a lot of time. i just have a hard time finding a good used swingarm for my exact year of bike. does the same 2003-2008 rule apply with the fitment of the swingarm? i heard that the linkage mounting points are different throughout the years but i have a hard time believing that they changed it every year. can i buy any 450r swing arm from this style of bike or do i need to find my exact year and stick with it. or is there some magical way to get these outer bearing races out? any help is appreciated! Prefere to keep it cheap also.. college student budget
  2. i have a 2006 crf450r and i cant figure out which bearings go in which hole on the shock linkage arm. are there even different sizes??? how do you know what size to put where?? thanks for the help!!
  3. Alright so i cut the bearing race using a de-burring bit and then that weakened it enough to tig weld a tac next to the cut and 180 degrees from that and use a punch to tap it right out. Thanks a lot for the help guys! Worked great!
  4. dude i bought some arnette series 3 goggles and wasn't expecting much because they were 25 bucks but they actually were very nice and they have never fogged up on me and i live in Utah and ride in the winter. the lens options were numerous and cheap. highly recommend.
  5. "how could riding be hard? you just sit and push the gas pedal.." haha i made a whole thread about this girls comment
  6. alright! ill go try that right now! if it works i will be the happiest man on earth. those arms are like 170 bucks and its ridiculous. you are a lifesaver
  7. Would the air grimder marr up the inside of the arm? Would it matter that much if it did? Id assume as long as the new bearings can still fit its not too big of a deal? I could be wrong though
  8. hey guys im removing my linkage arm bearings on my 2006 crf450r and didnt have any trouble pressing the bearings out except for the lower linkage arm bearing. im not sure where to even press this bearing out. the bearings were pretty well disintegrated and rusted to all that is left after removing the collar is the bearing race.. and its pretty rusted out. i got one sides bearing race out by using a punch from the other side but this side is too rusted and theres nothing to tap on. any input would be grand. thanks!!
  9. Got it running great. Aftermarket springs fixed it..
  10. The stock springs only have around like 1/4 inch between the coils they are pretty thick. The ones that are supposed to be on it are thinner but theres 2 springs to make up for it
  11. Nzgsr and i didnt even take off the exhaust springs so they most likely are not mixed up. Unless rocky mountain ATV sent me the wrong parts and labeled them wrong
  12. No idea. Like i said.. No labeling. It would just compress the springs till the coils touched eachother. I have to buy a thinner double spring set-up which is what was already on the bike but broke. I took the head into my local motorcycle shop to double check my theory and it has been ok'd by 3 different mechanics.. All very experienced and ive worked with them a lot and trust their judgement. They were thinking it was most likely a stage 2.
  13. Thanks for the post! So i found out my problem.. I did not realize that the guy before me had put a hotcam with greater lobe on the camshaft in the bike so the stock size springs would not compress enough for the cam to fully rotate. You would think that the cam would be marked so you could tell it was not stock but there is no markings! But my timing was right like i thought and i ordered new springs. Thanks for the help!

  15. I did valve springs because one broke and the guy before me put the wrong springs in when he did a top end.
