The new shock mounts are greatly improved.  My hat's off to anyone willing to do things over until they are happy with their work, so well done!  Your hoop looks fine, however you should check it for tire clearance (didn't see if you checked this already - please disregard if I missed it).  This is a very common error - sometimes even by people who should know better.  Easiest way is to mock up the rear wheel with the suspension fully compressed.   I invariably use a single shock without the spring as I like to have the rear suspension able to be placed in any position for many things (checking fender clearance , brake linkage, exhaust, bodywork, etc.) and recommend you do the same, but I think most people don't bother removing the spring and collapse the suspension with a ratchet strap which works fine if you are only checking for frame clearance.

I'm hoping 'minininja' already checked that, it's been an issue since at least 2009 and sme bikes have been completely re-built to correct the problem. Often just fitting  longer socks works. I made new shock bases. for a CB650 that had 2" clearance with 4" suspension travel
It was kinda 'interesting' to ride when the wheel hit frame

lol I did - it will contact the tire if I don't put shocks on there. but the shocks I have will bottom out with about 1/2" clearance

too close, I know, but "vintage riding" style (just cruising) I have never bottomed out a shock

I really should have used an "upswept" loop, and with the seat and cowl i'm using now I could have, but at the time I was going to use another seat... and this hoop was needed

Half inch clearance at full bump is plenty, even 1/4" would work as wheel won't generally stay that far 'up' for more than a few milliseconds
Check after a few hundred miles, no 'polishing and your golden (expect to see some marks from dirt and water though) Using correct rim for tyre also helps, putting a 110 on stock rim gives a taller tyre compared to being on a 2.15" rim. 3/8" is generally considered minimum to allow for tyre 'growth' at high speed.
The effect is most dramatic on Top Fuel drag rails, tyres grow about 6~8 " (or more?) and get 'narrower' as speed increases

Got to work on tank mount
cut off the frame mount, trimmed down the tank mount
using the hole already there, welded a piece to the frame, cut a hole. Will use a rubber bushing in between or maybe even a grommet in the tank part. I want to use a knurled thumb screw - because this part will be slightly visible with the seat I am using.


sorry for shitty photo

Choke plates were worn from the screws being loose for a long time, The are tight and staked but without fitting new plates there isn't anything that can be done. It isn't a problem though as the stainless steel connector also acts as a spring to prevent the shaft moving side to side (the flap isn't moving on the shaft, it's the entire assembly )
I didn't remove the connector nut but looking at gif, there may be a washer missing between it and carb body. It still won't be a problem though

yea it looks like they were jumping around in there for quite a while! amazed I didn't even notice

thanks for fixing them! I am super stoked!

as for the washer, I tried snugging it up with a washer, but the movement of the thing is way more than a washer can take up, unless i back off the screws and move it so it's centered when closed - which I don't really want to do now that they are staked in
