I think I see a lot of new parts there! These projects have a way of taking on a life of their own. Very nice progress, the JDM color looks great.
Merry Christmas and Happy New Year. Looking forward to the continuation.

(Replying to MauiK3 previous post)

Yeah, my standards are pretty high (borderline OCD lol) and had to make a call between restoring some parts vs. Replacing with new.

I’ve hoarded a few parts over the years that have made their way onto the bike.

The cost of replating and rechromjng parts here in the Uk has gone through the roof in recent years.

So new parts include:

NOS Front fender (Honda)
NOS rear fender (Honda, UK spec)
NOS OEM wiring loom
New Honda/OEM bolts/fastners
Repro rear shocks
DID rims

Etc etc…

James, the last post has some sort of glitch in the display, weird, maybe it's only my end.

James…. Looks fabulous. Where are you getting solenoids with the “strap bracket”?
Happy New Year!

James…… no pic. The after market solenoids around here come without the bracket that goes around the barrel and is drilled for small mounting bolts. Curious what your are getting and if you reuse the original bracket?

Managed to get a few hours on the bike this past week (seriously cold here for the UK, so not spent much time wrenching).

Wheels came back from the wheel builder & were fitted with new Conti RB2/K112 tyres. I love the Contis on these bikes - they look period correct and ride really nicely on UK roads.

Rear wheel fitted, managed to tear my hair out for a few hours, wondering why the wheel wouldn't fit - realised I'd somehow mixed up the outer LH spacer with a CB750F1 that I had re-zinc'd in the same batch. All sorted now & fitted.

I had the rear brake hub liner replaced a couple of years back and had this hub on the shelf, so nice to finally be using it.

Fitted the rear indicator mounts & will build a set of indicators from stock parts I have here.

Front wheel pre-assembled with NOS Genuine Honda brake disc.

All bearings replaced on both front & rear hubs.

I found a NOS genuine Honda K3-K6 seat in my stash, so for now I'll fit that until I find a bit of time to rebuild the K1 seat I was initially planning to use. So the seat latch was swapped for the key-operated type to match the seat plunger.

I suspect I may go down the K1 route eventually, given that I'm using the JDM Silver K1 body set, and I know the later seat match will just irk me lol. I just don't fancy trying to fit the original K1 seat cover to the painted K1 seat pan I have here in this cold weather, in case I split the vinyl. 

Waiting on a few bits to arrive from the usual suspect (CMSNL/DSS).

Was planning to order a few more bits from Yamiya but struggling to navigate and order on their new website - what a clusterf**k that site launch has been for them.

Carbs are on the bench being cleaned/rebuilt over the weekend.

Gauges arrived back from the gauge builder last week & look NOS.

Somehow, these projects seem to gain a life of their own, and what was supposed to be a light recommission ended up more of a high-end build. Typical me - just can't leave them alone lol.

More updates next week as they happen. I'm targeting a March 1st first-fire.

James… Who does your “instrument restoration”? Does he have a website with pricing. I’m looking for an alternate to posting stuff to the USA. Thanks!

I noticed that too, since Marcel left the stage getting instruments done is a challenge.

Photo dump - will write a more detailed progress update tomorrow, but pictures pretty much tell the story.

I think the silver may be a bit of a ‘marmite’ choice, but on first impression I have to say I love it.
