Very nice, can't wait to see the frame... ;)

Thanks for the link in the Brembo thread about the Airtech oil tank inner fender. I saw that and am considering it. Let say it is on the table.

No problem... ;)

Made a few iconic swing arm frame mounts.  No fun machining 4130. These are the pieces built into the frame as sort of a socket for swing arm to fit into. The swing arm uses two bolts instead of one long axle. The bolt is custom, like a shoulder bolt with disc on the end with holes to match the frame mount. The  cluster of holes in the frame mounts are threaded. The bolt disc fits into the socket and then screwed in. You then attach the nut on the inside to secure the swing arm
It is quite the elaborate design. I have no idea why it was done this way.
Much better way to do it, but this build is all about cloning.

I guess that commits you to building the correct oil tank, Eh!

 

HAHA, I have to brush up on castings 101 first.

Actually, the proto type HB1 didn't have the front oil tank. He actually put the tank at the  rear of engine under the swing arm in pivot in front of the rear wheel. That is something I have pondered. 
Still I'm thinking stealth inner fender oil tank. There is one on this forum that is exactly what I was thinking.

Knocked out a pair of mounts for rear sets. Out of respect, I'm using  Italian made Tarozzi rear set.

The only thing I don't like about the HB1 frame is, the rear tube coming from the swingarm pivot up to the rear shock mount, I would bring that forward so I could run a more modern shock angle..

May I ask, what tubing spec did you use for the frame and for the swing arm? Curious as to there the weight came from is why I ask-

The frame looks pretty good.  If you used chrome-moly, I'm surprised it's not lighter.

Is the swingarm mild steel?

I suspect may still be lighter than stock.
 What really matters. Is what are you gaining, and in that respect, even heavier (or more reliable ), is still worth it..
