HI,

I am trying to swap the triple tree stem of a kz900 with a zx9r 96, and i need a reference to a good motorcycle machinist, or anybody in this forum who could help me with that. I know that some of you guys have done wonderful jobs and have the expertise and the machinery to do it.

Thanks.

You will need to press out the stem from the kz example lower tree and press it into the ZX9 tree normally a bushing will need to be made I recommend taping a small fine grub screw through there to for good measure.

And bolt it on your done go ride.

What about the steering stops ? Plus, i need to use the kz900 console(speedo, tack) on the zx9.

Im not sure but I put zx7 forks on my 750 and the ID of the zx7 stem was the same as the OD of the 750 stem. You may want to check that out. I just cut the stem off and inserted my stem. The steering stops take and cut them off and Use large allen headed bolts tapped into the lower tree. Reference "Pens z1" here. The gauges you'll probably have to get creative and make a bracket. He Irishwill also details that some in Pens z1 thread. Although he made his own trees so it may be of no use.

I started into this once and realized my stem is welded to the lower tree - is this factory? How could you press it out? Grind off the welds?

Grind out the weld, be careful not to grind too much, and press it out.

some of the zx stems have a c clip in the bottom as well. my zx9 1996 had 1. i only found out when it forced its way out the bottom. no harm done though. u may be able to cut the zx stem off and just press the kz stem into it.then drill and bolt.B) if the hole isn't big enough , u can turn down the kz stem until it will fit. Simple , really.:laugh:

here is my top tree. i just cut the KZ gauge tabs off and had them welded onto the ZX9 tree.

Thanks Mark for the Photos.Very nice job. What about the steering stops ? Was it difficult to find the right angle for the tabs ?

Hello>>>
I have made my own triple trees....mostly because using "stock" gsxr or other such front ends usually ends up with rather limited steering>>>>not too bad on the street but makes parking lot turns a pain in the arse.
I have half a dozen or so top clamps here as well as 2 bottom clamps(they have a headlight bracket built in)
they are based off the stock geometry of a gsxr 1000.
if you search "pen's Z1" in the projects section there is quite a bit of info there.

I am working up north for the winter so I only get back for 8 days every 20 days away>>>let me know if there is something you need and maybe I can help you out.

Ben

then knocked the stem out of the old tree with a punch and hammer.

it has a step machined on the stem which makes my job easier.

the o.d. of the kz stem and the i.d. of the zx stem are just about.010 thsnths different.so i chucked up the zx tree and bored the stem out for a light press fit for the kz stem.

i then took it to the mill and milled the stem flat with the tree and pressed the kz stem into the zx tree.

the kz tree is thinner than the zx tree,so the kz stem only goes about two thirds of the depth in to the zx tree.that is enough,i will weld the kz stem to the bushing (zx stem)that i built and this will lock them together.the snap ring that is left on the zx(bushing)stem will keep them from going any where.no need for a set bolt.

that is the rundown on installing a kz stem in a zx tree.
