Awesome build, except for one thing. No offense, but in my opinion, those 750 letters belong on a mailbox, not on this beautiful bike. The quality of everything is top notch, then you have those stickers. They just look too cheap, and shade-treeish. No offense meant, just an opinion.

Shade tree, my backside.  I spent a lot of time designing that aspect.  I like it.  I think it adds a bit of an old school race element to the build.

I shot the firsts coats of clear on the tail section.  Gotta let this cure for a week, sand it and hit with some more coats until all the wood grain is filled.

Hey, if YOU like it, that's all that matters. Forgive me for the unsolicited opinion. Can't wait to see the final product. Awesome bike.

The wooden tail section is gorgeous bud. That's a lot of talent.

Thanks, fellers.  The basswood stripes came out more orange than I was hoping.  I used it because of the pale color.  I've worked with it before, but never used this particular urethane clear on it.  The clear is water white, no yellow tint.  Don't know why it turned so dark.  I knew it wasn't going to be a perfect match to the stripes on the tank, but was hoping I'd be close.  Oh, well.  Gonna run with it.  On the other hand, the walnut matches the Sunset Bronze Mica almost perfectly.

That's what I've used it for, but I always put a hard finish on it.  The stuff I used on my rear tail piece was more dense and a little heavier than what I've used before.

OK, so it's not much, but it's the first chunk of wiring.  Much more to do.



More parts arriving.

Oil pressure gauge...


Speedo, which I think I'm going to have to make a bracket for...


Kick starter shaft cover...


Brake rod...

This is my first venture into the realm of lithium ion motorcycle batteries.  I can't believe how small and light this battery is.  I made a cardboard mockup about two years ago using the dimensions on the Antigravity website so I could make a battery tray.  Today the real battery finally arrived.  Fits like a glove.  The battery is actually a little shorter than the mockup.

I must be doing something right.  The tail light and the brake light work with the key switched on, like they're supposed to.  I'm wiring everything brand new from scratch.  Nothing is stock.

Tail light...

Brake light...

I've been working on the wiring. I've got just about everything working...headlight, tail light, horn...I got the solenoid engaging, but don't have the starter connected yet.  I want to do some other things before I try a test crank.

I haven't installed any switches yet.  Just touching wires together to test things.  I've been working my way up to the handlebars.  Now that I'm there I finally ordered the hand controls and switches.  The switches came in yesterday and there's a problem with the Spiegler handlebars I bought last year.  They have a textured coating on them that makes the OD bigger than it's supposed to be and the switches won't clamp on to the bars without a big gap on one end.  I suspected I was going to run into a problem when I installed the bars into the risers by the way they were fitting.  I don't want to run into any problems when I install the hand controls.  I ordered some Biltwell Trackers today.  Hope they work out.

The Biltwell handlebars arrived so I am now able to start fitting the controls and finish up the wiring.

I made a new V-shaped speedometer mounting bracket out of stainless steel so I could mount the headlight switch in the same location.  Took me a while to figure out the best place to mount it.  I don't think it will look to conspicuous when I get it all buttoned up.  I also made the C-shaped bracket that wraps around the bars out of stainless and the brass spacer that keeps it all wedged in place.

I bought a Motion Pro speedo cable for a CB 360.  Its three inches shorter than a 750 cable.  Looks like it's going to work great.

The controls also arrived, but I'm sending the master cylinder back.  The package was opened and it looks like it was installed at some point and knocked around a bit.  It has a few scuffs and scrapes.  It's supposed to be new.  The clutch control is fine.

I found a three button switch housing with two buttons on the front and one on the back.  I'll probably use the two front buttons for start and horn, and the back button for the engine kill switch.  I won't have any buttons or switches on the clutch side.

Nice job on the speedo mount, Bud.  Looks clean.    I think you will like those bars, should be a comfortable riding position.

Thanks, Steve.  These bars have a little bit more pull back on them and are about two inches narrower.  They feel pretty good and the controls FIT!
