 No Kawasaki to Honda conversion bearings? I'd have never guessed that. What a sh!tty situation they put you in, they really should accept your return since they should have a recording of your original call preceeding your order.

Maybe roll a sleeve from cold rolled steel?

Ya it is a crappy situation for sure. I have the other bearings ordered. Once they get here I will do final measurements and install races. Then I will have a machine shop make the sleeve, install it on the stem and go from there.

All balls have lots of conversion bearings for other Kawasaki's but not the one I am using apparently.

New bearings are ordered. Have the local all balls dealer I got on of the bearings off of checking to see if they can get me the dust sheild and spacer separately that way I can keep the kit intact and hopefully resell it.

I have an email into the company in the UK I got the second bearing from, which was the more expensive of the two to see if I can do a return.

I have been talking to a machinist about doing the pressed sleeve for me and he said it is no problem so that is a win. Just have to wait for the bearings to show up before I can go ahead with that part.

If neither of the companies don't accept returns I don't blame them. It was not their fault.  Lesson learned, trust but verify.

New neck bearings are in. Bottom race installed perfectly, haven't done the top yet.

Had to modify the all balls dust seal. Had to remove the lip on the outer edge to get it to sit where it needed to in the neck.

All is well now and I am off to the machinist on Monday to have the sleeve machined for the stem.

The machinist took care of the sleeve for the neck stem no problem.

Could not resist doing a full mock up to get an idea of the overall stance. I am really digging it.

Yes it is stock rake. The front end and wheels are off a 1981 kz1000 ltd.

The kz front end is 4" longer than the stock cb750k front end. Plus the kz front wheel is a 19" vs the stock 18" of the cb750k.

Just ordered this for the scoot. Has high and low beam. 4200k. Should work out nicely. Will have to fab a bracket to mount it but I have it in my head how it will go so should be pretty straightforward.

I traded my bender for the kz1000 LTD parts I am using on my cb750 sohc. I contacted the guy and he wasn't using the bender so I offered to buy it back. He agreed. Bent up a template for the sissy bar I am building last night. Very happy how it is coming along.

Absolutely. Was just working on the sissy bar for a few minutes. It is bending up nicely. Bit of trial and error but that is to be expected

I still have this that was bought in the 1970s on my K5 750. I wasn't the original owner of this bike but knew the original owner and worked with him at the Honda shop. I was the parts manager and sold him this forked bar.
I don't always have it on the bike. The fork bar slides in (and out) of a square tube of the rail brackets(the brackets and fork bar were part of the package) and is bolted in place.

I also had one on my own red K6 back in the 70s

The trident is done. Local shop did the final welds for me.  Not perfect but am happy for my first time making one.
