Just got hold of of these forks, and the ECC in the right leg doesn’t work, googling has proven inconclusive…
Can this be serviced/stripped?
Any help or pointers appreciated.
 
Does it have the correct amount of oil? If the oil is to low it will not function.

Looks like 150cc of oil in that side of the leg. Pobably best to drain the oil out of the top of the fork, cycle the ECC until it's empty. Add 150CC's of fresh oil (Golden Spectro 125/150 is stock) and cycle the ECC until no more bubbles come out.

You'll want to do this with the fork compressed, so let all the air out before hand.

Thanks for the reply.
I’ll investigate.
The “knob” is almost impossible to rotate, can you advise on removal and strip/clean?
