Beautiful work John, and I know all about long balls, I sat on mine yesterday! Those K70 tyres look great, I bought a pair for my Suzuki T500 because the wheels I bought from the US were shod with 40(+) year old K70's and with the limited rides I've done on it, they feel fine. They were more expensive than the Stinko's I usually buy, but worth it for that "Period" look. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Terry..... I mounted them on my K0 and they really do look “right”. I did use the Shinkos on the Rickman and they look good there. Perfect price to roll around on and first rides!

 I’m taking my time on this one, enjoying it one part at a time. Hub and fork legs are ready. Despite more snow, heading out to pick them up later today.

Are the early tires block front and back? I've always thought it was rib front block back.

 I used the conti twins on the nugget, I ran continentals way back when and liked them. The diecast got K70/K81? something like that.

I believe you are correct, but I’ve used this combo a few times and it looks and works well.

Picked up a few shiny bits today. A few years ago, I found a local guy that polishes parts for local Hot Rodders and “Big Rig” truck guys. Works for cash (very reasonable) and considers my parts as “miniatures”! I need to clean the black “swarf” from the holes and threads, but nice work.

Next on the work list is to finish the front end and get a wheel on this project. I’ll be happier when it is safely clamped on the work table. I’m cleaning up the set of red fork ears that are the originals to this bike. They are definitely “well loved” but 754 FRANK convinced me. All the original red bits are getting polished up and going back on. I hope he’d have approved. He was really annoyed when I sold the Carlini Chopper last year. Partial Atonement?

The purist will shout “over restored”. I don’t care.

 I like it shiny too!

It’s tough to keep shiny, but for +20 years I did a lot more of it! 1957 Lotus Eleven, Series 1. I restored and raced it from 1986-2007. This “three wheeling” shot was taken at Waterford Hills, Mich. Note the twist in the outside wheels. Broke a lot of spokes.

I find today’s “expert restorers” are not polishing even close to what was original. They claim to have the correct scratch patterns and finishes. The same for frame paint.

True! I did follow the advice on paint, but the polishing is to “my choice”. My biggest challenge to my self is to reuse 99% of the parts and hardware that came on the original machine. It’s easy to just order new…..

Last week I complained to Vintagecb750.com about a set of new fork caps that only screwed into the new tubes a half turn and then stopped. I stripped all the chrome off the threads and then worked them with a metric thread chaser file. With some good anti-seize compound, I worked them in and out a few times and they were just “acceptable”.

To their credit, I received a written apology, followed the next day by a set of new tubes and two sets of caps! New caps threaded nicly into the tubes I’d already assembled, so nice “spares” on my shelf. This week I plan to finish the front end!

I'm now in the orderering phase due to some parts I had extra I bought a registered frame to 1 1/2 year ago followed by other parts. All small stuff cost some. Ingnition cover has silly prices!

But fork tubes only must be safe. ;)

PeWe..... I’m safe! I traded the tubes today for some parts I will need for this project.
Got the fork tubes assembled today using a seal driver I built for the K0. Worked perfectly
Will remember to take some photos tomorrow.

Got everything ready for wheel building (front) and the rear swing arm, fender and tail light fitted. Starting to look like a bike! My buddy Gary came by and we hoisted the engine into the stand. He’s so “Covid Bored” he’s scraping and washing down the engine before we pull the head. I hate that job, so fed him a very nice lunch. He earned it!

Steve.... a friend had a few castings done locally and they really look fantastic. The block and head are so hard to prep that I’m excited by any option. Did you paint or leave unfinished?
