Assuming your bike is ready to ride, tank empty is actually the wet weight. Dry weight is without engine oil, fork oil, battery, etc., so your bike should easily be sub-400 lbs dry.

your bike look great in orange....


.I also use the light bracket form a 81 kz that mount to the gauges bolts.

I switched from the old stock reg and rect when I put my Z1 back on the road again to the combo unit. works great, don't fry batteries anymore and leaking acid all over my machine. The one big problem over the years has been the permanent magnet rotor becomes sloppy over time causing a knocking noise. I have one extra but bought another one on ebay. At first it looked good but when I put it in a vice and moved it one way and the other, I cold tell it was starting to do the same thing. The seller ignored me and time ran out for refund.This seems to be a problem with this design. In 78 I had one seize up. I managed to get the cover off after hours of trying so I know that noise. Maybe that's why K went to the all electric type. I'm going to stiffen up the V bracket from the steering head to the down tubes. On the Z1's they always cracked in the same spot. I will also add another tube just above or below the swing arm pivot. The Susie's had a tube going from the steering head to the cross tube like yours. I'm planning to do that as well. Good Job.

Have you looked at these?

Universal 35/39/41mm Motorcycle Headlight Mount Bracket Fork Ear Bobber Chrome

Now they are 41mm but I wonder if a 1.5" sanding drum could get them to work. They are pretty nice and are available in black and aluminum finish as well. Then there is always Dime City

Lastly could you adapt a head light bracket from a Kawasaki ZR7?

got the brake anchor machined last night.

now just need to get it welded .


kraber,
it depends on what your application is going to be,as ed mentioned.
the swingarm on my black z1r i pictured is 3" over stock which is what i felt i needed to get the gaps above and in front of the wheel where i thought they looked the best.
because i also added structural rigidity and a larger contact patch the extra length has not negatively affected the handling.if i was to go much over a 3" stretch you are getting into pro street /drag race territory.
prices vary on swingarms depending on material and design.

all of my contact info is on billybiltit.blogspot.no/ hit me up and we can work out exactly what you want .

No eBay APP ID and/or Cert ID defined in Kunena configurationI got the brackets off of ebay, the post would not load on the previous comment. Apparently ebay links are broken today. Here is a web link

No eBay APP ID and/or Cert ID defined in Kunena configurationI found some 54mm head light brackets, and used my original bucket. If you need more info you can PM me.

It was quick and simple for now. And cost effective. Unlike some other components. Lol

Interesting..

I am going to look into this.

I picked up a couple gear clamps and made my own bracket, used the stock headlight bucket
