Anti-Dive Shim Kit

Post by Auggie »



I have been trying to order a ante-dive shim kit from Motomfg. Are they still in business? I have tried to order and also email them with no success. Any info on another company or them would be appreciated.

Try ebay. That is where I first found motomfg. I cannot see him going out of business. It would cost nothing to have a few of these things around. If you cannot get one, then drill a 1/4 inch hole in a nickel and put it in. Just be careful tightening the screws, as you will be a nickel thickness shorter then you were. Cheaper too.

So I bought the anit-dive shim and installed in my 2013 1800 GL. I was talking to a friend today who does some Honda work and mentioned the shim I put in. He said that he wouldn't do that as it increases the pressure in the shock and will blow the seals. Have any of you that have installed the shim kit had any issues. I would hate to have to replace the seals in the tubes. Any comments would be appreciated.
Thanks, Auggie

I think your friend is correct, as the forks dive more with the anti-dive disabled then there will be higher pressures generated at the seals, however Honda did engineer the forks to travel across the full range of movement, so they must have intended the seals to experience this pressure. In general, most people that disable the anti-dive also fit new stiffer front forks which dive less under braking so the pressure increase is very small. I disabled my anti dive 7 years ago and fitted Progressive springs, I have covered over 30,000 miles and have never had a fork seal leak, so the risk seems very small to me.

I cannot see it being a problem. I would think that the anti dive would be what would increase the pressures. How else would the anti dive work? Without the anti dive, the two forks should be experiencing equal pressures. If the right one can take it, the left should be able to. The anti dive is the item on GL1800s, along with the weak front springs that are most complained about. It was the very first thing another GL1800 owner asked me... if I had disabled the anti dive. Next was, was I having cupping on the front tire, and third was, was I happy with the front suspension. I had all these things fixed within the first thousand kilometers. I have not been dissatisfied with any of the things I fixed. Disabled anti dive, changed to Progressive springs and put 43 pounds of air in the front tire. (increased the rear to 40 also). If anything would be considered the cause of front fork seal leak, I would think it would be the weight of the bike.

Don't let him work on your bike. He needs a bit more education.

Thanks for all the great feed back. I did put the shim kit in and now putting in the Progressive front springs. I hope all goes well and the ride is better than before.
