Anyone know 80's Kawasaki's - anti dive

[marksx]

I'm currently (read - years into) doing a resto on a 1983 GPz1100 and I want to disable the anti dive on the front forks.

I understand the nearest solution would be block off plates but I don't know any machine shops.

Does anyone know if removing the brake pipe and fitting a blanking plug will have the same effect?

Thank you

When I disabled it on my RD500, I did just that, removed the pipework and IIRC inserted a banjo bolt into the unit itself.

Thanks Podman. If I understand the drawings correctly the brake pressure moves a piston stopping oil flow and stiffening the forks so no pressure no restriction.

Just need to find the right thread bolt now

As a none bicker and lay person, can I ask why you would want to? Just interested is all.

It's an outdated idea that manufacturers ditched once fork technology improved. I've replaced the original forks with modern progressive ones.

Can be removed, but the block-off plate has to have a bypass groove milled into the inside face.

Should be able to find someone to make them.

Although with modern semi active forks anti dive is alive and kicking albeit with a different and more effective implementation.

I run it switched on all the time and find the bike a bit unstable on the brakes if I switch it off.

I was just about to say this.
I'm assuming you have replaced the fork springs not the whole fork?
I was going to go this route with my gpz900r

I did just this on my GPZ900R and put ZZR600 front forks and rear wheel on, worked really well. Wish I'd not sold it know. I also did similar to a 1990 ZX10 by adding ZZR110 forks and rear wheel, another bike I should have kept unfortunately life etc gets in the way.

Yes, just the springs have been replaced
