i am needing help designing drawing a tone ring to be laser cut from stainless the od is 137mm id is 102mm 60 rectangles of the 3mmx8mm size rounded corners also on the od i am going to need 4 ears with mounting holes 136mm center to center  ill have measurements for their id soon 

this is for a possible wheel swap for a 17inch rear wheel  and a 17 or 19 inch front      here is an example their are 60 flats on the ring on the cb1100 not holes if that makes sense

now that i read it the bolt circle will not work i may just have to make a hub adapter to use the oem tone ring

maybe we can draw a hub to mount the cb1100 tone ring to a flange that uses a 4 bolt 136mm adapter basically

pcd of the 3 bolt on the cb1100 ring is 80mm holes are 5.3mm

I would make a thin steel disc that covers the CB500X's rear ABS pulser disc and has 3 holes to align with the one from the CB1100.  You could braze. silver solder, rivet or bolt them together.  
You would have to assemble the wheel into the swingarm first to determine the critical spacing of the pulser disc and the pickup.  Then you could then, with a little trial and error, make 3 identical length spacers (plastic, aluminum, steel) to fit it.  Once the proper height is determined, you could make the final spacers of steel, thread them then braze/silver solder into place.

that could work as well

i found a place that can make the sprocket spacers easy enough if i could get help making a drawing of the hub for the reluctor i bet that would be a easy turn also for some one else if they ever needed to make one for other honda 4 bolt brake disc wheels

Creating a 3D model for this ring that could then be used for CNC machining is actually very easy. I would do it for you, but I'm retired, and don't have access to a computer with 3D modeling capability. CATIA is the most common 3D modeling software out there, used by almost all of the aerospace industries in the states, and abroad. If you don't personally know anybody with access to CATIA software, I bet you could go to your local college campus that teaches engineering, and find a student willing to work with you on this. An experienced modeler could create a 3D model of this part in less than one hour. Our local college (San Diego City College) even has the ability to create a 3D printed part (plastic), which would be a good idea to do for fitting and size purposes before you contract a machine shop to build you your final part.

Bummer. I've looked for threads on converting to 17" wheels here and on the old forum, but I can't find anything that's really useful. What I did find suggested it was a difficult project.

anything can be done, just depends how much access to equipment you have.
Personally, on this bike, i dont see the benefit.

In this case the Cush drive would have to be cnc d and im not putting that kind of money in it maybe i can score some res wheels

m in sci put some ex500 mags on a 72 h2/H1 hybrid years ago for a friend, and had to mill the carrier hub into the wheel to make the offset work, like said, it can be done, did it on a j head.  I just don't see the real benefit of doing this (or what tim did for that matter).  you could cut one down, make the 'fingers' for the cush, and tig em in as well. just a thought.  but i love doing stuff of this nature so...



the benefit would be tire choices also looks also you would have to add to the wheel not mill it shallower or have a new drive hub machined

how far off is it? you can use a carrier adapter and move the sprocket out pretty easily. rebel gears in Tennessee (highly recommend)  made one for the RD to bring the rear sprocket out about 10mm when i built custom wheels for is using a european rear disc hub, then putting on wide spoked wheels.  they can do further though.  i was able to get an offset front sprocket and they did the rear carrier adapter. been on for 17? years or so zero issues.

More than a inch witch would put the sprocket far left of the Cush drive bearing and cause issues i have a place to make a space no problem it’s the geometry of where the sprocket ends up in correlation with the drive bearing would laterally stress the bearing too much leading to premature failure
