Glad you sorted that out, at least you had a spare to fall back on rather than sweating the problem of finding another...

The yen to dollar is more favorable lately ranging around 150 yen to a $ US. Does that mean Yamiya parts are more affordable???

Their stuff is still pretty costly, but fast shipping and quality make it good value.

$8-9000 John

Closer….

$11000  :)

Close enough we can stop!
The total with bike purchase, right?

Yes Per. Remember this was the “parts bike” that came with the crazy chopper, so not exactly a large number! It seems, full restorations don’t get any less expensive. Rechroming original parts and professional painting of the frame etc., has made this one a little extra. A lot of hours on this one too, it’s been in the shop 2.5 years now.

I like the look of that nice chopper;do you think the new owner rides it,rather than just letting it sit ?

He’s on this forum and had the engine “freshened” by Cyclex. Haven’t seen any post lately. It’s a very good looking bike, but a little weird to ride! I left it exactly the way the original owner built it in 1974. His family has a very large farm in south western Ontario, with a superb machine/workshop on the property. His workmanship and attention to detail was really exceptional. Real Time Machine.

Bench sync on the carbs today. First step is to set the 4 idle needles to a “T” mark on their shanks. This ensures the slides are all sitting evenly, just cracked open. Virtually impossible to measure, but they looked right. Next, set the top adjusters so each cable had between 1-2mm of slack.

The second photo shows a cable lubricator and a pair of vice grips (not clamped to the cable, just hanging as a spacer). This bit of pull sets all four slides up off the deck. In the second shot, you can see they are all a bit different height.

#1 carb was the lowest of the four. I polished up the shank of an 11/32” drill bit and it just scraped through the opening. A very minor adjustment on the top furl nut got the other three more less equal to it. Should start on these settings.

Here’s the set up I use to warm the intake manifolds. I leave the heater on the lower setting for about 15 minutes. It warms everything up nicely!

Because the four cables come up through the frame, everything has to come out for the install. These carbs are a true pain.

With the head and manifolds really warm, the carbs just pop on, with almost no effort. The manifolds are new, which really makes a difference.

The heater has a disabled tip over switch, or doesn't have one, or it was bypassed or reoriented...
Yes, new carb rubbers and side cover grommets are definitely the way to go. Crazy that you got a K0 with the chopper and it has turned out so nice is a testament to your efforts and investment in effort, time, and money... Lots of sweat equity invested

David…. Yes. The “tip over switch” is definitely modified. It’s just a piece of duct tape. The Sandcast is a real bonus and the chopper was fun too.

Got all set to fire it up and the battery is flat. On a trickle charger now. Decided to call it a day!

Just like the kawasaki triples, a truely archaic setup. The two strokes were slightly more forgiving at and throttling off idle.
Start with the end in mind...

That's a great idea, and one I gotta remember for the next one! When the owner wants the engine test-run it is always a wrestling match to put the carbs on. Taking them off after the run is always SO easier. I do it as soon as I can touch the head again. :D

I rigged it up one winter when the shop was really cold. Worked so well, I use it every time. What’s really amusing is that heater belonged to my mother in law. She ran it under the card table where she played solitaire ‘til she passed at 99 years old. She smoked like a chimney. It still stinks whenever I warm it up!

I use a heat gun I constantly move over and in the rubber boots to not heat too much.

That heater might heat more evenly without rubber burning heat.

Do not tight the clamps to much when rubber is warm and soft.

Later Honda carb boots are softer than the older shipped in transparent plastic bags with red Honda print and paper labels inside.

I have a NOS set of the older ones for K1-K6. Rubber seems to be more durable.
Another set for K0 I ordered late 80's for my K6 but got wrong model.
K0 is shorter at head spigot side.

John,the 21"? front wheel may be too large(going to an 18 or 19" fr. wheel could improve handling)and make the bike handle/corner Way Too slow,but it does add something to the 'Look'.
The frame looks like an Amen?  or did they custom build the frame also?

Bravo on the startup!
The 21" front wheel was sometimes added to help stabilize the super-long forks at speed. It's sort of a 'gyroscopic assist', so to speak. But, the extra weight of it made for wobbly steering at low speeds as the tradeoff. This then led to skinnier wheels, tires, spokes, etc. to improve the in-town riding on Saturday nights.

Thanks guys! It’s super quiet, no chain noises or smoke. That’s on just the bench sync and static timing set. Vacuum gauges and timing light next time.
