Default CRF450 03 Forks Sloshy and Gurgling

     

Hi All,

I just changed my fork seals on my CRF450 and followed the manual to a tee... Everything went together well and didn't have any real problems. Although once they were all together they sounded a little sloshy, as in you could easily here the spring in the oil. I presumed that is normal and continued to put them on the bike. I took it for a ride and when I got it home and pushed down on the forks while holding the front breaks and realesed it, I got a gurgling sound from the forks as if oil was draining out of somewhere like the fork dampener drain holes or something...

Could it be that I put too much oil in the forks?(I tried to be as accurate as possible and put about 412cc in each fork, thats not including the fork dampener)... Has anyone had this problem in the past?

I've never been inside of CRF forks, but did you bleed the cartridge rods?


I don't even know if CRFs have them...lol oh well just thought I'd throw it out there.

Hi drman,

CRF450's have a push dampener rod which I did bleed so dont think that is that. Thanks for the suggestion though... If there are no more suggestions then i may have to start from scratch again which I really really really dont want to do :-)

Hmmm, I've rebuilt my forks twice now, and I didn't have anything like that... Did you do the inner chamber too? Wondering if it just didn't bleed all the way or something. That's odd. I'd take a look for sure...

Sorry I'm of no help, but I will move this to the suspension forum so maybe our suspension guru's will know what the deal is.

hey Woody_CRF... thanks for your reply but I have found the prob and feel like a complete idiot... Because I had almost a full tank of fuel, when I was pushing on the front forks the fuel would gush up under the fuel cap and when it was running off it was making the gurgling sound through the over flow pipe... Because the pipe sits between the forks it sounded as though it was the forks...

I dont need to pull the forks apart again which is a relief :-)

Thanks

just wondering woody or 450stylz what did you do use to break the 50mm locknut on your forks? I am going to make mine from 3/16 in. thick 2 1/2 in. flat bar. unless you guys know a cheaper way....

hey tHeKiNgMaN, well I actually went out and bought a 50mm socket to crack that locknut... Its a huge socket but did the job... it didn't really cost me all that much (about $20 Australian Dollars). The actually locknut wasn't all that tight at all when I first un-did it so you may be able to get away with a wrench if your really really really carefull. I think the lock nut is only aluminium and damages easily. I have only just put new seals in my bike so if you have any questions at all dont hesitate to ask... Have fun

I should have gone that route too, but I spent the $40 on the tool from race tech. It's 6 sided and works well. Be really careful when you take that off since the head is made of brass and really soft, so you can jack it up really easily.

well this will be the second time that i have done this and it was a read pain to break them the first time with my pump pliers... lol.
Probable because i took them out before i cracked them...hehe.
well this time i fought for a while and they were really stuck. so i phoned around and the honda wrench was like $92can which is outrageous in my mind, then snap-on had a 12-point socket for like $65can but 3/4in drive so the adapter was $25can. Well to heck with that these are just fork seals!!!! no way im i paying more then $30 bucks for any wrench!!! So my last option was to rig something up. What I did was i went to the local scrap yard and picked-up some 2 1/2in x 3/16in thick flat bar for two bucks. yeah thats right two bucks!!! what a deal. after i cleaned it up i took some paper and drew out a 50mm octogon and cut it out. i then coated the back side with glue from a glue stick then with some precise measuring (left eyeball) i pasted it on the flat bar and traced it out with a big black marker and pealed it off before it dried. note . do not move it around after you get it on or it will screw the lines up from the marker. end note. ok so now i have this octogon traced out with black marker and i take my trusty center punch and banged it at every point. then 1/8in drill bit to drill them all out . then come the dremel. note. i used 3/16in flatbar cause 1/8in is to small and 1/4 is to hard to cut with the dremel. end note. all i did was cut the lines with a mini zip disc. first fit was pretty close all i did was grind it out to the proper fit.
BAM $2 wrench!!!

this fix might help the financially disabled and if it proves to be useful should be rewriten so it can ledgeble as well.

Happy riding!!!
