Me too. Let it dry thoroughly after a good scrub with a wire brush (in my cleaning tank)then seal it up with a couple of coats of Tremclad Silver Rust Paint. Nobody will ever see it but I like it to be finished. The front fender is a new one I had, so leaving it alone.

Very nice build John.  I certainly agree with the Zen of wheel building.  I've only done one pair of wheels but it was very satisfying and gets an impatient person (me) to slow down and relax.  And yes, the first wheel took me at least 3 tries to get the lacing pattern correct.

I still have a rusty old pair of wheels sitting in the barn. If I get confused I can always lay them on the bench. It’s been a while since I needed them.

The bike looks very nice John. Always bugs me when the clutch cable is in front of the speedo!
Yeah, me, too!
For a [brief] while there were some (5cm?) shorter clutch cables out there that didn't do it so much, but they disappeared after a couple of years. Seems the clutch was harder to pull, probably because of the kink it caused at the cable adjuster by the lever.
A lower bar, no clutch cable in front of speedo.
I think the cable is 114cm long if I remember correctly

This bar a little bit wider too.

Those bars were quite long before you cut them;do they apply good leverage to your control of the bike? How do they feel with comfort during rides? The also look a little like Superbike bars.

Really nice feel and handling.

Looking at the specs from Highway Hawk on their Fighter bars they are @ 3" rise and 3" pullback 36.5" wide(cut 5-6mm each side off= 80-82cm/30"-32" wide)

https://www.highwayhawk.com/highway-hawk-handlebar-fighter-920-mm-wide-90-mm-high-for-7/8-22-mm-clamping-chrome

4into1 in California has a similar bar to your cut width Per, at 32" wide, 3" rise, 3" pullback. They call them Street Bike bar.
I might go with them next, I bought their European bars which are 30" width, 2" rise, 4 1/4" pullback a year ago. They give a bit stiffer turn in handling than I like,  though are comfortable so I might get the Street bar over the winter. The extra 2" width might help with the turn in handling.

Winter arrived here today. Spent a few minutes in the shop and got the rear fender back on….. With a spotless wheel and fender, I’ll have to shine up the grab handle, turn signals and stalks next. One job leads to the next.

The centre stand looks cruddy with the frame polished up, so that will come off too…….. Oh well, +5 months until riding season, so may as well do it right. Still ordering parts, no lock tabs on the rear sprocket!

Good timing too…….. It snowed again this morning so 5 months before I need any motorcycles!  Rewired and finished up the tail light. The grab bar is in nice shape except for some slight fuzz around the turn signal brackets. Soaking in “Australian Terry Juice” overnight. The bike seems to have exploded apart today. I pull two bits off for every one that goes back on!

Back end is all back together. Waiting for some new lock tabs for the sprocket nuts. The side and centre stand look crappy so I’ll do them next. I’ll have to wait for my buddy Gary to show up for a shop day, before spinning the bike on the table. The front wheel needs to come off. It will need new spokes to match the rear!

Oil tank needs a good scrub and I need to find the “missing” hose! Will have to head off to  “Lash’s” place to pick up the motor too. Putting this off until my daughter comes out for a few days. My wife is walking without the cane (wearing an inflatable boot) but still don’t want to disappear for a full day…..

This bike came with a “fresh” 1974 K4 engine that I fitted to the 1974 Rickman CR. The replacement is CB750E-2563239.  Only +1000 numbers off my frame, so a very nice, coincidental fix!

A while back, “Lash” posted on here about his vapour blast cabinet he built himself. This engine started off with all the bits he put through it first. I have yet to see it, but I bet it is really spotless!

Did a bit more, late this afternoon. Side stand and centre stands get a coat of paint and shiny new springs, with a new pivot bolt.  Cheap $10 improvement that goes a long way.
      While searching for the ownership reminded myself this bike has a very nice NOS Honda seat, including an Owner’s Manual (repro) in the compartment. The PO spent some money on this thing…… I did transfer the ownership into my name, ages ago, so good to carry on.

Not sure where you got that engine number John. This one is 2452000 which puts it near the end of the Canada run. Last one shows as 2465992.
