mal-adjusted ICSV.
the piston had been wound too far down the bore by the top nut.
so a full strip, clean and check, and on advice from Another Cossie Specialist altered the inner heavier poundage spring slightly in length thus pushing the piston further up the bore agains't the lesser top spring.
Once reassembled i was Gob Smacked that it worked perfectly.......
I thought as it was i was going to have to leave it disconnected anyway so i had nothing to lose by trying, and sure it worked a treat.......
Thanks anyway for the help
If you have any idea's why im still getting the 1+2.........
