Bummer about the clamp! Too bad he doesn't offer single ones for situations like this!

Can you elaborate on the 2/3 dynamic? What's the effect and is it possible with electronic ignition?

Dynamic timing with a timing light. I ran out of adjustment, so based on this:

The first 'clue' here is" you have a K2 and the points plate is new manufacture. Check for "looseness" in the whole plate against the ridge that is supposed to center it. I recently bought an OEM (TEC brand) plate set, and the diameter of the plate is slightly small on int. I had to lift the plate upward toward the top "ridge" and set a feeler gage in the bottom lip (to hold it there) while adjusting things. This worked out well in the end, and I cinched the screws down like that.

The gap: it can range .012" to .016". Usually with the TEC sets, they come in around .014" to .015" when thy "hit the marks". I usually set them with a .014" gage statically, then run a timing light on them to find the "F" marks by adjusting gaps "live". Afterward I make sure they fall within the .012"-.016" spec.

I got it right on the F mark, but I forgot to double check the gap with a feeler, and it looked smaller than the 1/4 gap.

Electronic ignition... no idea! I don't use one.

Pretty bummed about that, since now I have to find ONE stainless hose clamp with rolled edges. Balls.

Have you checked McMaster Carr? Not sure what size you need but hopefully this link works. Wait, I just realized that you want a single clamp...oh well, I'll post this anyway.

Found out one of the bigger disadvantages of a 4 in 2 exhaust - you have to sort out which pipe goes to which cylinder.  I gave up after about 15 minutes of the cat trying to 'help' me and threats of rain.

Try again tomorrow.

Received my breadbox air box today. Vintage one through eBay. It even includes the original rubber stacks, but they've hardened up a bit. Might replace them. Needs an extra layer of perforated metal to wedge some filter foam and tape to close off the sides.
Stripping the chrome and painting it flat black, like the engine.

Nice! How much did it run you? I got one off eBay a few months back for around $50 shipped i beleive. I also was going to paint mine black (Not sure if flat, semi gloss, or gloss) to match an engine as well.

Keep me updated!

Great deal! I got mine for $120,- inc shipping. Was the only one on the whole wide web I could find. $30,- shipping to the Netherlands.

Sanded all the chrome, 100-180-400 grit and wiped it down. Using Berner paint, really nice cover in the first spray. Apparently heat resistant as my engine rebuilder used it on my engine without problems.

Made a McGyver spray booth in my garage, works really well!

People are after original breadboxes?

I have one in the parts box, might be a bit rusty, I may just have to pull it out and chuck it on eBay.

I just put a breadbox on my f0...and am really impressed.  With light green UNI foam sheet trimmed to fit it runs great...120 mains, airscrews 1/2 turn out, all other settings stock except for a properly baffled 4-1, it has perfect part throttle response.  It  does seem to want a little more choke for longer than the stock airbox, but it is still cold here in Michigan.
If it works good, it looks good...

Went for a nice ride around the reservoir. Still a little chilly, especially when it's cloudy. Bike feels really great. Sometimes though...happened twice... the bike shuts off when I come to a stop. Almost always when I slow to pull into my driveway and every so often at a light or stop sign. Idle is about 1,100 or 1,200.

Also, building a new seat. Round bar skeleton. Maybe this week I'll skin it with sheet steel. Yes, it's very Kott-esque. He makes nice looking seats.

Thanks dude. You mean in terms of materials? Not much so far. 1/4" rod and 18ga steel is pretty cheap. Something like $30 so far maybe...that doesn't include the English wheel or ring roller I had to buy for this project though, haha. But I'm a firm believer in gathering as many tools as possible to help fabricating.

Dave,  I noticed you've mounted rearsets almost exactly where I'm planning on running mine.  If you don't mind me asking, how tall are you and what's your inseam measurement?

Blood type and sperm count too? Haha

I'm 5'6" and inseam is 31". It fits pretty well, but if it was any farther back it would be uncomfortable.
