Thanks for all that info!  Very useful!  I would be easier to just put some VTR lowers than adapting the CB1 lowers.  I'll weigh it all out.  For now, I'm fine the way it is.   I was just kicking around different ideas. 

I will post when I get back into trying to troubleshoot it.  I don't have Facebook and this forum is really inactive at times.   I was on FB for a bit with a fake name and I got kicked off!

The grinding of the welds was well away from the structural part.  There was a lot of extra weld towards the rear of the swingarm that lines up with the sidewalls.  I didn't grind away the welds completely. Just smoothed them.   Yes, that would be dangerous if I did remove the welds.

I probably could have checked specs on which tires.  It was what was available at my tire guys shop and at first check, it cleared but barely. 

The front disc was easy to spot the difference.  I was going back and forth on the two choices that you also mentioned.  I finally went with the shouldered bolts.   I didn't want to drill and tap.  That's a no going back option.  I figured if 6mm is strong enough for a VFR, it should be ok for the smaller cb1.  Maybe, it is 8mm because it is a single vs dual?   

Yes, that is a better way to have designed the spacers.  Good idea.  Dropping the spacers on the right - yes that was a PITA.

Changing the rear disc wasn't a priority (yet).  I didn't want to relocate the caliper for a smaller disc. 

The front fork lowers are CB-1.  So stock caliper for now.  I have VTR calipers too.  The Brembos mount weirdly and yes the adapter will look kinda chunky there.  Not decided which route.  I will consider the VTR calipers which is likely the same as what you mentioned (CBR, RC, etc).  It might mount more elegantly with a smaller adapter.  It will depend which direction the bolts will mount.

I wanted minimal downtime and most of the work was in the late winter/early spring.   But now, she is stubborn and won't start.   No spark issue I am chasing.   I just pushed her into the trailer for now until I get time.    Mostly riding the Hawk and VFR for the time being.   Plus the CB-1 still has no exhaust.

Haven't ridden it yet but I will play with it then.    The front was bolt in but the rear needed custom spacers machined.  2 on the outside of the bearings and the one collar between the cush and wheel.  Bearings too to make it fit the OEM 17mm axle down from 20mm.  A small sleeve was needed to keep the 20mm f2 spacer inside the wheel from moving around.  It would have been better to lathe down the 17mm CB-1 part, which is longer than the f2.  Tire selection is important as the tire, though centered is very close to the swingarm.  I grinded down the welds smooth inside the swingarm to buy a couple mm's of clearance.    The 520 chain is pretty spot on for the chain line too.

I'm also planning to adapt a Ducati 999 Brembo 4 piston/4 pad axial caliper.

Thank you, stussels!  Waiting for my new TIG welder and I can get the exhaust mid-pipe done. I will either do an OMT or Kerker can.

I got my bike late last year and have been upgrading it with parts from other Hondas.  During the recent lockdown, I've been busy doing some more work.   Here is the list of most of the mods:

Rizoma mirrors.
VTR1000 clip-ons.
VTR1000 switches, modded to fit OEM harness.
VTR1000 throttle tube and housing.
Pazzo levers.
VTR1000 choke cable & bracket.
600F3 front wheel with new bearings and CB-1 310mm rotor.
VTR1000 upper cartridge tubes with CB-1 lower stanchions and brake caliper.
600F2 rear wheel with custom aluminum spacers and collar.
Dunlop Q2/Q3 tires. 120/70 and 160/60.
520 chain conversion. JT 15t (CBR500) and Vortex aluminum 38t rear.
CBR1100xx shock.
CBR900rr side stand. Need longer stand for longer shock.
Vortex CBR929 rearsets, re-drilled to fit.
Rear HRC style reservoir.
CBR929 gold rear brake caliper.
Graves spool kit, redrilled/tapped for 8mm spool bolts.
Modify harness for MOSFET regulator.
LED turn signals and TST electronic relay.

I still have to finish the exhaust and tune the suspension (especially the forks).  I'll fab a mid-pipe to a high mount slip-on can.   Stay tuned.

Good info!  Thank you!

Does anyone know if an exhaust from an NC23 can be modified to fit?   I believe at least the primarys will fit since it is the same engine basically.  I'm sure after the mid-pipe, it will not.   But a bit of cutting and welding can be done.

Does this mean this shock will still fit the VFR or is it modified for only the CB-1?

Yup, same mental condition! I don't think I've owned a bike stock for very long.   But i wont go too far with this bike tho.   There is a point of no return.  I don't want any mod to disable it for more than a couple weeks.  I built my my Hawk with advanced CST and it took more than 3 years!  This will not happen here.

It's more about the fun.  I don't have to.  I have the bad tendency to just tinker.  Nothing will be irreversible.

Here is one pic of the cb1 with cbr3 wheels.  I'm not a fan of 3 spoke wheels.  The 5 spokers look so much nicer, IMO.

Yes, thanks!   My current collection is a custom Hawk GT, VFR800 (5th gen) and the CB-1.   A V2, V4 and I4.   My daily is the comfy VFR.

Not directly. But I saw one person do it on Craigslist. I saved the pictures and I got some information by email before the posting disappeared. The back wheel is the same size, the front wheel is slightly narrower, same front tire, rotor on same side. Fitting the back wheel should be a little bit easier, resizing the bearings, correct spacing and mounting the rear rotor and caliper. Yeah a little bit of engineering needs to be done.! I've done a few wheel swaps on other bikes. The process is pretty much the same with a a little bit of machining and measuring. What could go wrong? Ha! Oh and it helps to have a 3D printer to speed up prototyping.

What's the best way to post pics on this forum, besides dropping in a link?

Check my sig for now.  My Flickr album is there.  I'll keep it updated.  For now, she is hibernating in the trailer.

Future mods include cbr300r wheels, 900rr throttle/start switch and 929rr rearsets.

Troy MI.  I got it in PA, around September last year.  I will post pics later, maybe tomorrow.  I've been a member here for awhile (even with no CB1). I recently left discouraged by some of the negative posts lately.  Decided to come back since I really don't like FB.  Hopefully I will get a better experience this time around.
