I've done some polishing before, and I know that my time is much better spent doing other things.

If I was single with no kids and no desire to save up some money to go racing again, I'd be doing everything I could possibly do in my humble shop.

Engine mounts are back, it should all be downhill from here to the finish.

Figured out how to sling the engine and manipulate it to insert the tranny mounts and tranny.

Image

Primary system installed & shimmed out, alternator rotor installed, primary chain adjusted, clutch installed & adjusted, new gasket with a light smear of sealer, cover installed, all nipped up.

Hint: insert the main footpeg square-shanked bolt FIRST, and don't tighten ANYTHING till ALL the hardware is in place!

Image

Still have some daylight, so what the heck - progress shots -

Image

Image

Correct wiring harness and new seat cover scheduled to be here tomorrow. It's finally starting to look like a bike...

Put everything away, posted the last few shots, washed my hands and did some paperwork and the postman knocked on my door with this:

It'll go on tomorrow, with the fenders.

I can't imagine having a bike so shiny. Even my new one wasn't that clean, nice.

My camera hides the dust and fingerprints except in the macro closeups and some flash shots.

It WAS shiny & clean, and it WILL BE again, right before I deliver it.

Wiring harness in place, like-new Lucas rectifier installed-

Image

New Zener diode on cleaned up heat dissipation fins-

Image

Rear fender & support loop installed-

Image

It's getting down to where finding the remaining proper matching hardware takes more and more digging. It sure is nice to have all clean fastener hardware...

Tail light installed, I need to buff out the original Lucas lens-

Image

Front fender partially installed, I ordered a new front mount because the old one was going to take too much work to repair the twisted bottom lug.

Image

Bloody thing takes SIXTEEN bolts & eight nuts!

Also dug up the bevelled head screws and secured the upper gaiter mounts which also secure the lower ends of the headlight ears, and got those done.

Sorted a few other bits & bobs, test-fit a few items and set aside matched hardware sets for next week's push.

Setting up the magneto timing with my trusty dial indicating caliper using the plunger and going by the book at 11/32" BTDC on the piston crown with advancer chocked at full advance. It took a bit to get a stable, repeatable stup, but pressing the caliper body against the flat of the finned section and seating it solidly on the spark plug hole seat, it was dead-nuts-on three times in a row-

Image

Apparently, that equates to a little over one tooth at the crank pinion-

Image

I didn't happen to have a "cigarette" paper handy, so I used a piece of very thin carbonless receipt paper and adjusted the points to the SLIGHTENST drag (equivalent to a cigarette paper slipping free)-

Image

Chopped off the modern blue crimp bullets on the three alternator wires and scrounged some wire segments with Lucas bullets to make for a neater match to the new harness-

The punchlist is now getting pretty short to reach the start-up stage-

Replace timing cover oil seal and install tach drive & cover (parts on hand)

Parts needed:
Carb rebuild kits
Needles & needle jets
Oil manifold pipe gasket

After that, it's basically add fluids and "give it a go".

Finishing up will be very few items-
Seat cover to the upholsterer as soon as it arrives
Instruments back on the bike when they get back from precision overhaul
Chain, front brake cable, ball-ended clutch lever
Decals and detailing

Looks like having it done & test-ridden before take-off time to Barber's is reasonably within reach. I estimate 20 hours, with a tad over 3 weeks to go...

"Just to give you an idea"

Seat cover is long overdue, but tracking says it's inbound; for now I just set the old seatcover in place for a mockup shot (sorry for the blurry shot, too hot & tired to re-do it)-

Image

This side looks better-

Is that the right front fender? It looks like it is for a bigger wheel.
You probably want to go into town, and find a up to date Jap Bike store,
With a full spares department, a clean workshop, and kean young mechanics.
And ask them if theres a Grumpy Old Bloke out in the Hills, who knows how to fix Real Motorcycles.

I have yet to mount the front fender brace (should be here today or tomorrow), but it is indeed the correct fender. When it's done, it'll have equal daylight all the way around between it and the tire.

Finally got the seat cover in, Canada post is SLOW!

Anyway, it's all down at the upholsterer's.

Just waiting on the carb kits & oil pipe gasket to get her started up!
