That sort of mileage is pretty normal if you ride hard (fast accels, high speeds, etc).

Good to know. I wouldn't say I've ridden overly hard, as the bike is new to me and it is my first SOHC. Don't want to push it until I know more about it's reliability, how it should run and the sounds it makes. Mileage is really no concern of mine, because I do like to ride hard. But, I feel checking mpg early on could be a decent gauge of how well I have it tuned.

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.

My fork clamp black again since many years. I glass blasted it 1983, it looked so good so I clear coated it when I did my tank at the same time.
Today black again.  Photo taken when pait is still partly wet. 2 additional thin layer sprayed afterwards too.
 (Place for handle bar cleaned with acetone after the photo was taken)
New handle bar clamp with pilot lamps to match it soon here. Correct placed blue lamp named Highbeam as my K6 has.

Had my forks rebuild, packed them up really well. Got them back in the same packaging with fragile tape all over and they looked like this:



Postal service dropped them, hard! Rebuilder will mill and grind them, new anodizing and back in business. Problem is, I don't have to time for it now. So will have to wait till September ends (yes, Green Day pun intended) when I come back from Spain.

Yeah, it is total BS! Especially since it's the national carrier around here...

The sender is responsible and they quoted me around €300/$375,- for the repair, which should be covered by insurance. It's just a huge bummer since it cost me €200,- to rebuild them and I've been so careful with them.
Nothing I can do now, so putting my mind on other things like how to paint over my chrome covers. (Yes, I am going to attempt that..)

New K&N Air filter. Woo. Ordered direct from K&N website.

The #2 carb clamp that I got in a set of 8 from Carpy (http://www.cb750cafe.com/) has stripped. So I put one of the original ones back on with a new (unstripped) M4 bolt. Pretty bummed about that, since now I have to find ONE stainless hose clamp with rolled edges. Balls.

Put the original float valves back in the carbs (nothing wrong with them, just an experiment with new ones last year), and set float heights to 26mm.

Once the child goes to sleep, I'll go do a warm-up run, and re-set the 2/3 dynamic timing again. When I was live-adjusting the points gap, I think I set it a little narrow. I'll knock the 2/3 points plate a bit further, then set it again.

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?
