Hi guys,
Sorry to hi-jack this thread but seeing as you lot know a lot more about these forks than me, I thought I ask the question; basically I have the opposite problem. The forks (888 RC 05 also) seem really stiff and not half as senstive as they previously have been. First we thought that the oil might be contaminated so I changed the seals and oil. When doing this I noticed that the oil in the rebound leg was filthy, but the oil in the compression leg was fine (very strange). Anyway, no luck - forks were exactly the same. Then I thought that I might have put too much oil in (although I'm pretty sure I put in 220ml), so I dropped oil, pulled the forks apart, and let them drain completely. When I done this, the oil in the rebound leg was a stinking grey colour again, and this is after one ride! I haved checked all internal components and there doesnt seem to be any evidence of metal on metal (although I havent pulled the cartridge apart). So I have put new oil in, this time only put 200ml in, and they are still exactly the same!! Really stiff!!
Has anyone had this problem previously? Has the rebound cartridge blown? Any suggestions?
Cheers.
Rog.

have you crashed hard on them recently?? they could be twisted which would make them stiff. you also need to flush the lowers with enw oil, rather than just change it. simply put new oil in, and wash out the internals with it, however, after riding it with new oil, this should have done just that. its a tough one. maybe a bushing was damaged somehow in installation/removal? what happened between them being smooth, and them being horrible?? ooh, try leaving the bike upside down to drain the oil to the top side of the cartridge, youll have no compression or rebound daming after cycling the fork a few times. all you should feel is the spring as resistance and a bit of bushing/seal friction. cycle the fork a few times, check if it is feeling sticky/stiff, this could be worn bushings/seals or even just crap in the seals and should be able to let you credit/discredit the oil as being the factor thats causing your forks to be sticky. wassell
