Monster Marzocchi Fork Internals
I just picked up a 2008 M695. It had about 7500 miles, but I don't know its complete history. Therefore and because its fun, I'm going through the whole machine, checking, cleaning, and replacing things. One of the jobs I'm doing is the forks (seals and fork oil).
It has non adjustable, 43mm forks. I believe they are Marzocchi according to what I've read. I pulled them off, checked the guts, cleaned them up, and replaced the oil and dust seals. I was putting new fork oil in them (Belray 5wt, which may be a bit light, but its what I had on-hand) and was working the damper rod to bleed the air out. On the right fork, as I bled the cartridge, I was able to feel normal damping resistance as I bled it and added fluid. However on the left cartridge, following the same process, I never felt any significant damping resistance. In fact, I did it twice but never got any significant damping resistance.
Any ideas why? Any chance these could be the types with rebound in one side and compression on the other? There was some compression resistance on the left side at the bottom of the stroke (which the right side didn't have). But it seems to me the left cartridge may be bad.
Any help or experience would be appreciated.
