cb360 swingarm chop

It's late. I'm sleepy. Had a couple cocktails. Cut me a little fucking slack here.

I can be MUCH more acerbic in the morning before my first cup of coffee. :)
 
No been busy. The risers showed up and I bolted them on quick and left. Ill have it back at the shop in a couple weeks to finish welding.

How far ya moving them? You do the math for new height?

Haven't re-measured anything yet but I'm guessing somewhere between 3-4in forward. I think it would make most sense to put the shock at the same angle as a stock bike. 3-4 should get it there but like I said I haven't actually taken tape to anything yet. Spent most my day out at an antique bike show.



 
You should reinforce the swingarm so that you don't get any bending. The added leverage of the additional length behind your shock mount will impart some pretty significant bending force on the swingarm.
 
That red Panhead needs to come to my house. My all time favorite bikes to own. Done well they make really nice riders.
 
The owner is really loving it. He took a couple days off of work last week just so he could ride it around. He's not a small guy, so he is looking forward to us upgrading the front forks with new springs and emulator valves.

Thats in the plans as well. Question tho. What do you think would be a better option for bracing? A full hoop (red) or just adding some plating to the sides (yellow)?

 
I would make the plate that the axle runs through extend further forward. It doesn't need a LOT of reinforcement, just a little. Extend that plate forward as a gusset top and bottom, and it also serves as a place for your shock mount.

The red "girder" that you drew is way more than is needed.
 
Back when I was building stuff like that, we just welded 1x1 angle iron to the base of the swing arm. Adds a ton of strength, and if the welds are laid in cleanly, looks really trick... just a lot of cleanup involved, the angle iron HAS TO blend smoothly to the base metal. Tack, trim, weld solid.
