The D spacers are discontinued so this seller is taking advantage of it....

Just make your own by grinding an edge into a washer. Not difficult.

True, I have done it. Trick is getting the correct thickness, the spacer is thicker than a standard washer.  I believe the cylinder head washer is the correct thickness.

Yeah I read that the thicknes should be .09 and the cylinder head washer is at .093 so it just needs filed down a bit. Ill check ebay for them. Wish there was a honda store around! Any suggestions on a good wiring diagram? Like a smart guy I didnt take any pictures of the wires and want to make sure I hook everything up right.

If you have the OEM wiring harness in there just connect color to color. Plug and play :) Everything that goes into the headlight bucket gets connected to the main harness which also comes into the bucket. Be sure to check for corrosion and some guys put dielectric grease on the bullets too.

Unless I'm mistaken, on a 71, the front turn signals have green and black pigtails.  The greens hook up to greens but the blacks hook up to light blue for right and orange for left.  Again, this is a 71,don't know about a 70.  fwiw, this is coming from someone that's colorblind

That's correct, but those indicator pigtails have a short colour-coded band (featuring the correct light blue & orange colour) over them close to the bullet connectors.

Great. The p.o. has done some hacking in here. My turn signal wires are grey and some colors arent on the harness. Mine looks like a total mess compared to yours. Also is my bike a "sandcast".  I will post pictures asap of the bike.

I have a thread in Tricks and Tips about this. Yes its the CB750 cyl head washer (maybe others) that is the correct thickness. I'll get a link. Strongly suggest you not using a standard washer as I've seen the tree crack with them as well.

What is your engine number? If under 7414, then yes.

Thanks! Everyone always asks me and I could never answer them. Will hopefully have time to play with the bike these next couple weeks. Would like to put it on the road this fall. As of now electric start doesnt work. Looks like the wires that run through the bars are disconnected from the bottom half of the controls where the button is. REALLY short.
