Gl-1800 anti-dive unit disable

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!!

I got a piece off ebay that was machined to fit in between the anti dive valve off ebay for 20 dollars, no leak, others have used o-rings and even nickles with holes drilled in them.

Cheapest method is a Nickle with a 7/32" hold drilled dead center. Stops the plunger and fits the recess area perfect.

I have both a nickle with a hole in it, and a oil drain bolt washer.

Thanks fellows.

I have just completed to temporary fix. Used the washer.

Brother Richard - next entry down - thanks for the additional info.

Cliff, to each their own. I am not an advocate of disabling the ADV unless you have upgraded your suspension. If the ADV is stuck, I would clean it out and make it operational again. Worse case, I'd replace it. The fact that it is stuck solid leads me to believe proper maintenance was not performed on the bike. This is just one person's opinion, so take it for what it is worth. Good luck with whatever you do.

Good information from everyone, maybe I am missing something here..... Where do these special made or eBay purchased do-dads go on the bike? An illistration or picture would be nice. Inquiring minds want to know.

That do dad comes with two longer bolts. It simply bolts between the upper and lower half of the anti dive valve. The thing costs 20-25 bucks and shipping whatever that might be. Maybe shipping if so called free??

The nickle trick is the best, or if you are sure, just saw the top plunger tit off. Put it back together.

Preacher Cliff. Check out the step by step section in this forum and look for anti dive fixes. Good informatin there. I used some o rings and the problem is solved. I plan to upgrade the front forks and when I do that will disable the ADV but not until then. Good Luck
