This is what I recall:
To disable the anti-dive unit on the 1800, separate the two halves and insert a oil drain plug sealing washer between the two halves and tighten.
There will be no fluid leak, and the two bolts will be long enough to secure the unit with the washer in them.
My ANTI DIVE IS STUCK OR SOMETHING, ROCK SOLID - NO COMPRESSION OF FORKS. TERRIBLE RIDE!!!!!!
IF YOU HAVE MORE CORRECT INFORMATION OF WHAT I HAVE GIVEN, OR IF YOU KNOW OF A BETTER WAY TO GET THIS JOB DON, PLEASE TELL ME!!!!!
THANKS A BUNCH!!
