This is a continuation from the "Sanity Check" thread below. 2005 YZ250F Now we have a problem. (Caveat - I have used Dave J's cartridge bleeding procedure with good success for about ten jobs now). As discussed in previous thread, I used a 7mm spacer on top of the ICS spring. It did not work. With that spacer in there, the damping rod will only go to about 4 inches from the end of the cartridge and stop. Dead stop, hydraulic lock feel to it. I'm thinking the free piston would not raise high enough. I never could get any fluid to purge from the transfer holes. Perhaps the ICS spring reached it's mechanical limit. I took the 7mm spacers out and now the rod will go to within about 2 inches of the cartridge end and stop with all the same symptoms as above. On my 5th try now and no change. I have never had this problem. On my last try, I backed the base assy cap out two full turns (Raising the entire assy slightly) and the rod moves all the way in normally. This system is 100% stock and I am sure no one has ever opened it up. I took the base assy apart to make sure the ICS spring retainers are positioned right and they are. Everything in this system is stock now except for removing some HS shims in the compression stack. Bazaar!!!! Anyone have any ideas what could keep the piston from traveling it's designed distance upwards?? This entire system looks brand new, not a scratch or burr anywhere.
