    CRF 450R street legal?

    So, I'm curious, has anyone had any trouble with their bikes holding up to road use? Sometimes dual sport requires on road riding of an hour or so at freeway speeds to get to a trail. I figure it'd be o.k., but wondering if anyone has had any trouble here wasting their motor or tranny. Thanks folks. ~D

    A shim program?? Where did you get that?? I've only had access to trial and error, but it's worked out well so far....

    I found some 08' stock fork springs for my boys 05' CRF 250... anybody know if they're the same spring??? D

    By the way, someone on here mentioned that they like to get springs from a particular place because they have consistent predictable spring rates, and didn't recommend getting them from the usual name brand sources.... I can't remember who posted it, not Dogger, perhaps Kelstr???? Thanks folks, Duhfactor

    Interesting..... I pulled the right side fork leg apart on my boys CRF 250 to change the midvalve compression stack to the discussed one on the previous page, removing one 20X10 and taking 10 off the spacer... no problem. I noticed a shit load of sludge in the fork leg and couldn't for the life of me figure out how so much of it could accumulate there. The forks had been re-done by pro racing suspension evidently. I cleaned it all up, checked everything carefully, changed my stacks, and re-assembled with Maxim oil as usual. It felt kind of stiff to me considering the known valving I just did, but nothing ever bound that I could tell as I re-assembled things. Well, I put that leg in the bike, and got to work on the other one. I pulled everything apart, and it was as dirty as the first leg was. The suspension was so stiff before, I couldn't figure out why, thinking there was some massive stiction, binding or some massive valving in there. As I started cleaning, I realized... there was no spring in there!!! After looking all over the shop, I couldn't believe I could lose something like a spring!! Then, my boy, who was cleaning out the slider said..... "It's in here"!! I'm not joking, that damned spring was jammed in that slider so tight I couldn't get it out!!!! I yanked, pulled, used every tool known to man, and finally, after 45 minutes, got that POS out of there!! As I measured the OD of the spring, I realized that the OD of the spring was the same as the ID of the slider. You have to press that POS in with a ram to get it to go into the slider!!!! Who the hell does that???? So, I guess I found out one of the possible reasons the forks worked like shit.... I have no idea what those springs fit, but it sure as hell isn't an 05' CRF 250 R..... Now I have to order springs and tear the other leg apart again to replace them both. And folks want to send their stuff off to some company to "do their suspension"???? Hmmmmm.... Duhfactor

    I'm assuming there is an adjustment shim .10 thickness to compensate for the shim that was taken out, but has no valving impact??? I think I've previously ordered some when I thought I was going to change the midvalve on my 450..... what diameter would it likely be?? D

    On my 06" CRF 450, I settled on the following, and even love it on faster and technical trail riding. Base valve: 30X10 (16) 29X10 27X10 25X10 23X10 21X10 20X10 19X10 18X10 15X10 (2) Comp Adj. Stack 16X10 (6) 11X10 12X10 13X10 14X10 15X10 16X10 (6) Midvalve was left stock...... I run at 103mm sag, and need to look up my shock stack, as I like it pretty well. I actually changed my brothers rear shock stack compared to mine on the same bike, and I like his better for plushness and speed. I don't think I wrote it down though, and I'm pissed because I want to change mine like his, and am going to have to pull his apart to get the stack arrangement, I can't find notes any where... let this be a lesson to ya!!!!! D

    I guess the 10X20's on the midvalve really stiffened the compression up. I'm with ya on removing one 20X10 on the midvalve compression. Is it possible to mill the spacer at home carefully with emery paper on a flat surface??? D

    Wow...we think alike..... Before I pulled the midvalve, I re-valved the base valve like this: 30x10 (11) 28X10 26X10 24X10 22X10 20X10 19X10 18X10 12X10 Comp Adj. Stack 16X10 (5) 11X10 12X10 13X10 14X10 15X10 16X10 (6) I did the "pull every other shim" thing on the HS compression portion of the base valve because I really love the plushness on the small hits. I can always add some back in if needed. The suspension really didn't change a whole lot, thats when I pulled the fork apart and looked at the midvalve arrangement, and realized it was changed. D

    Any body know what the stock 05' CRF 250 R midvalve stack is? I just bought a clean one for my boy, which had the forks revalved for desert riding, thank goodness the stock parts were still in there. This thing sucked, couldn't hardly compress the forks during hard riding by ol' Dad at 180 lbs. The initial base valve set up was; 30x10 (4) 24x10 30X10 (4) 26x10 30x10 (3) 21x10 28x10 23x10 22x10 20x10 19x10 18x10 Washer 11x20 16x20 12x10 13x10 14x10 15x10 16x10 (10) The midvalve; Nut Washer 16x30 (3) 11X20 12X10 13X10 14X10 15X10 16X10 12X10 18X10 20X10 20X10 Piston 20x10 (4) with 8mm ID 10x20 (3) with 6mm ID I changed the base valve set-up, will post later tonight, but only improved movement a little. I want to start back to stock if I can on the midvalve, then adjust from there. I'm not very good at measuring float BTW, so maybe that had something to do with it too. I'm heading toward motocross, 140-150 lbs rider, beginner to intermediate. I'll post my CRF450 stack later that I love. Thanks, Duh

    We must have just missed you...We were there right when they opened, then left in the early mid afternoon, not sure exactly what time..But before I head out there again with the new fork valving (after I make some changes), I'll post it , and if you have the time, you'll have to come out. You can even ride my bike and see what you think of the valving changes. Have a good one, D

    Hmmmm. Sorry I missed you. I was on an 06' CRF 450 with a black jersey and grey bottoms. There would have been one yami 450 and my brother on another 06' CRF 450. Do you remember seeing a guy over jump that step down and start laughing???? It seems like I saw a guy on a yellow bike off to the side who saw it...was that you??? That was my brother on my newly suspended bike....If he didn't break it on that one, I'm not sure what would!!!! I love the rear end on that bike now. I'm going to work on the forks next when I get a bit of time... D
