Carburetor Rebuild - 1973 Honda CB350 Café Racer

This was a fun escapade. Completely stripped, cleaned and rebuilt the carbs. Photo essay follows.

As they started, replete with lacquered gasoline.

Yeah, the floats weren't in much better shape.

Removing the jets.

The vacuum sections were in pretty good shape. Note the beverage.

Skipping lots of boring disassembly photos (that I took to help me upon reassembly), Most parts went into the degreasing/cleaning bucket.

Then dried in the dish drain. (I'm divorced, so there was no argument over this. Highly recommended.)

After cleaning and drying, reassembled with new components.



Hooray!

Kickoff - 1973 Honda CB350 Café Racer

A few years ago, I purchased a 1973 Honda CB350 with the intention of turning it into a café racer. I've been working on it slowly and sporadically since then, so it's time to start a blog. Here's what she looked like upon purchase, before disassembly:













After a complete disassembly, the frame looks something like this:



I'm in the process of removing all the unneeded tabs and mounting points from the frame and cleaning it up. Then I'll cut the rear of the frame behind the shock mounts and install a hoop to match the café seat.

Several purchased parts will go into this build, including:
- Clubman handlebars
- Fiberglass café seat/tail
- High-mount pipes
- Lots of stainless fasteners

I had planned to re-use the forks, but found the fork tubes so severely pitted where they'd been encased by the headlight mount shrouds that I had to find an alternative. eBay to the rescue, where I found a great set of forks from a '74 CB360. They are the same 35mm OD, so the triple trees are reusable.

I completely rebuilt the carburetors, with new jets, floats and other parts, and they're ready to reinstall. I'm looking to get the engine running on the stand in the near future.

More to come, and your questions are welcome.

An open letter to Virgina Governor Terry McAuliffe

Dear Mr. McAuliffe;

You cannot be an unintelligent or uneducated man to have reached the position you now hold. I do wonder, though, if you are a logical man.

I am a law-abiding resident of the Commonwealth of Virginia. I believe in my family, my country and my rights as outlined in the Constitution of the United States of America. I also posses a permit to carry a concealed weapon, as I believe in the Boy Scout motto: "Be Prepared." I hope I never have to use my weapon in self defense. Should I be forced, however, to defend my life or the life of a loved one, I hope I will not hesitate.

I hope you realize that I am not the problem. That law-abiding citizens are not the problem. That tools in the hands of the law-abiding are not the problem. That criminals ARE the problem.

Criminals, by definition, do not obey laws, do not abide signs, and do not care about those who do obey laws and abide signs.

I hope you and rational enough to realize that removing the ability or legal authority of the people to defend themselves against crime does NOTHING to prevent such crime.

Any effort you take to deprive the law-abiding of their rights to self defense only creates more opportunities for criminals to exercise their unlawfulness, and for law-abiding citizens of the state of Virgina to die needlessly.

Please, please realize that the criminals are the problem - not the law-abiding - and do everything in your power to bring criminals to justice without affecting the Constitution-granted liberties of the law-abiding.

Sincerely,
Robert X. Xxxxxxx

Metabones Speed Booster Auto Focus - Finally!!

Prelim report on Metabones Speed Booster update with autofocus for Canon lenses (on GH4):

EF-L 24-105 - works beautifully. I think this is my new happy place!
EF-L 20-35 - check.
EF 50 f/1.4 USM - check.
EF 40 f/2.8 pancake - check (and a great, compact combination!)
EF 85 f/1.8USM - check.
Unfortunately, my 35mm f/2 (not USM) doesn't respond, and the 75-300 IS USM makes the camera freeze.


Bottom line: Hooray!!!! The AF is quick and accurate.

In all functional cases, autofocus engages when I first bring the viewfinder up to my eye. This is probably a setting I need to disable somewhere in the prodigious menu system of the GH4.

Note: This is all with the (now discontinued) standard 0.71x Speed Booster. There are two other versions now available: the ULTRA (still 0.71 - not sure what the extra is there) and the XL at 0.64. I'm thinking seriously about picking up the XL. If you're really bored, ask me about the math of lens equivalents...

Thoughts on the SLR Magic 25mm T0.95 Hyperprime Lens

Received my SLR Magic 25mm T0.95 HyperPrime lens today. First impressions:
  • It's heavy! It's tiny!
  • The geared aperture/iris and focus rings have a nice resistance to them.
  • Very solid all-metal feel.
  • It has a small sliding lens hood that won't stay in place without tape.
  • Comes with a threaded metal lens cap; very nice, but overkill. I'll be storing it in favor of a quick plastic cap.
  • Focus throw is about 180 degrees.
  • At T0.98, focus is limited to a few millimeters of depth.
  • Compared it briefly to a 50mm on my full-frame 6D; the 6D is still wider, despite the math that the two should be close to equivalent.
After some time to play with the lens, here are some more thoughts:
  1. Like most (budget) lenses, it's soft wide open. It takes on a 'dreamy' soft look, though, with focus limited to a few millimeters. At T2, it's very nice and sharp, still with a beautiful, even, soft bokeh.
  2. The small sliding lens hood is in fact threaded (and not, insofar as I've found yet, removable). The lens itself takes a 49mm filter; the hood a (much more common) 55mm. If you install a 49-77mm step up ring to the lens itself, e.g. to add common filters, the hood will contact the step-up ring when trying to focus to infinity (and thus prevent reaching that focus); the solution is to use a 55-77mm step up ring attached to the hood rather than the lens itself. This seems like a small detail, but has ramifications in certain applications. For cine lenses, it's nice to have the front-most lens attachment not move as focus changes. Attaching step up rings and/or filters to the lens hood enables this.
  3. A point worth highlighting: This is a COMPLETELY MANUAL lens, with no electronic communication to the camera. This means no lens metadata (i.e. focal length, aperture setting, etc.) will be recorded with your photos or videos. This is generally not a problem for video work, but might matter to a stills photographer.
  4. The aperture ring is VERY close to the camera body, as in about 1cm away. There's only about 2cm separation between the aperture and focus rings. Should you want to operate both these rings via follow-focus type controls, be prepared to get creative! The focus ring is so close to the body that I can't fit a follow focus on the traditional left side when using my GH4 and the Wooden Camera cage.
  5. That said, the built-in metal gears mesh perfectly with every follow focus system I've yet tried. Both focus and aperture rings have very little backlash/hysteresis.
Some photos:
T0.95 Soft!

T2.0 Nice and sharp, with good bokeh

T0.95 useless for wide shots

Much better when stopped down.

Can you be big enough?

Let me give you an example:
Every week, at my workplace (a publicly traded company), someone writes a Bible verse on a public white board in the main hallway. This is allowed and accepted, despite laws separating the workplace and religion.

If I were to express the offense I feel** at seeing this, I would be ridiculed and ostracized. If I wrote on that same white board--not obfuscating the Bible verse--a verse from some text I happened to believe in, it would likely be erased, or if not, quite a row would result.

This is because Christianity is the 'popular' choice here (where I live and work), and people are too ignorant to accept that different points of view and beliefs exist. "Not Christian" is equivalent to "Evil" in their small minds.

The point is: It's hard to express a non-popular opinion. At our American core, we all say we support free speech, but it's very hard to accept (or support or defend) the speech of those with whom we disagree, especially when it rubs us to an emotional rawness. Most are not intelligent or cognizant enough to understand, let alone embrace and realize, the distinction, or the importance that the distinction exist in the first place.

So what's the message? If you find yourself offended, angry, in a sense of outrage, etc., can you be big enough to view the situation objectively and be true to the principles?



**This is for discussion only. I actually take no offense at others expressing their religious viewpoints; I DO take offense at those attempting to force their viewpoints on me, or those who would demean my expression of my religious viewpoints.
