hi,can i use thicker washer under the shock piston coz the stock washer keeps bending and goes through the shaft,is it possible that im not bleeding enough oil.if i use thicker washer the piston will be higher and may hit the diaphram.thanks

maybe shock oil to thick + shock to hard try thinner oil or piston with bigger or more holes

yes,you can put a bigger washer on the bottom and not one on the top.or you can put two stock washers on the bottom and they will not bend as quick that way.A thicker washer would be your best bet though.any other questions,just let me know.
