Kosman frame bracing kits for the Z1 KZ900 KZ1000

I have been slowly putting my KZ1000 Superbike back together piece by piece. People been asking about frame bracing and where to put all the bracing needed to make the big KZ to handle. The frame picture here is what most people used in AMA Superbike racing from late 1977 to about 1981. All that thin plate gusseting around the steering stem is flat useless. Just remove all of it. Tubular bracing is the only answer to strengthening up the steering stem. Now if you add oversize motor mount bolts, and ream the frame and engine cases so that all the motor mount bolts are a interference fit or press fit. The motor becomes part of the frame. All other gusseting that is not shown is really not needed to strengthen up the frame.

Sorry about all the duplicates, the library in Prescott Valley just got hit by a HUGE thunder shower, then everything locked up and then went blank. Then all the duplicates popped up.

Do you want them deleted?

YES PLEASE!!! There should be a total of six photos with the listing. It is getting real scary here in Prescott Valley. The skies have opened up again big time !!!

I live in the desert too. I have a large wash the goes corner to corner on my 5 acres. It can be a torrent in seconds. I'll delete your removed posts.

Hey DR Gamma,

Do you still offer this frame stiffening kit?

Thanks,

Steve

I may be wrong , but I dont believe he was offering to make kits for sale.
Dave

Oh thanks Dave,

I guess I just assumed they were for sale since it was in the vendor forum.
Looks like a good idea to stiffen up things though.

Last time i looked, PMC has a bracing kit listed in their catalogue. You could contact Z1E and ask if they can order it.

My frame is an 81 GPZ1100 though. Not sure if it's in kit form.

I thought it would save on cutting all the pieces if I can find a kit.

Don't see anything on PMC's site though.

After I get my 440 back together and caught up on shop and house projects, If someone provides the appropriate frame and/or, as well as their knowledge with the Z1, 9 and/or 1k, cause I havent got a clue other than the 900 has a front wheel I want Also help from such individual in measuring, marking, cutting and fitting, I wouldn't mind opening the shop doors on a weekend to bang some bars out for the community I'm no motorcycle expert by any means, but Ive been told that my mutant power is the ability to easily spot problems and fabricating problem solving?
Also, I'm not in any way trying to step on anyone's toes or gain customers, he'll chances are it may not even happen? (that is unless you wanted to turbocharge your car ) sooo yeah,
