Saving a '81 KZ750-E

Why not putting risers on top of the top triple tree. Drilling and taping the top to fastning the raiders, or welding for that sake.

I did not like the idea of having the bars mounted by bolt through the thinnest part of the top triple tree. It is cast aluminum, and I do not have a TIG welder (and have never learned how) so I would need to pay someone to weld it for me. Add the time and expense of fabricating or modifying handlebar clamps. Since this build is a bit of a resto-mod with the modern front end, it was an easier solution to use off the shelf parts.

What ever works for you. I got to like the superbikes bars a lot, as you got the ĺeverage to stop a slight wobble to turn in to a tanks slapper.

The last piece of the front end puzzle arrived today. This will stop those little wobbles from turning into tank slappers.

Looks familiar!!!!

The best choice you could have made for a steering damper!!!!

Looks like the very same damper I used on my RG.

By reversing a bar clamp, I preloaded the lower front engine mounts outward .25" before welding.



After welding in the gusset plate, it came back right on the money. No change in distance! Lucky beats good every day of the week!



No, I don't weld the prettiest, but I get good penetration.

theres a joke in there somewhere.

nice work.

All of the bracing is finished. Now on to the steering stops and damper mounts.

I have been working on the new design for the steering stop. I had a couple of ideas, but went with the simplest design. There is a round post that extends down that the stock lower triple tree would contact with two cast tabs. I ended up welding a .25" thick x 1.00" steel flat bar on the end of that post - the edges with contact the outer edge of the Honda lower triple clamp. Sorry, no pictures yet. I will post some when I remember to bring my phone to the shop! :blush:

Looks like you have added a good bit of metal to that frame. What is your intended usage? It should make a pretty stable road racer.

Not sure if this link will work but this shows where the old skool racers guys used to brace the GS1000 frame (which is one of the better handling UJM's.) Brace point C is one of the more critical so you may want to go after that if you still have a hanker'n to add more.

There is still more grinding and fine tuning on the angle to be done, but I am happy with simplicity and strength.

I would like it to be a capable track day bike, with a vintage superbike theme. I will ride it, keep it for a while, then probably sell it to help fund the next project (what that may be God only knows!). Originally I wasn't thinking about bracing it, but when it was brought up it made too much sense not to.
