Another beer and a 1/2 needed to fabricate another brake arm mount. This one perfectly centered to the center line of the 9/16" clamp loop. Drilled for a 6mm screw. All that's left to do is radius the open ends. Should be in the mail Saturday.

Ya gotta know, to install these mounts. You have to spring/pry them open to get em over the chain stay, and then draw the hanger ends together enough to get the clamping bolt and nut started.
The assembly should be tight to the chain stay. "Like Aunt Lucy's corset strings." (credit Greg Knowles).

You were probably good with the first one, but I appreciate your level of detail. Would love to buy you a beer or two someday

Dunno Danny. haint seen Pat's sprocket adapter and sprocket assy. on your Husky rear wheel, set in the drop outs.
Brake arm torque is significant. First offset one was a less than perfect for my stay size, and reducing the stay loop size I could not center the hanger mounts.
Honestly making these mounts for you, are what I wouldn't do for my self in the days when i pulled a forty hour week.
I wish my shop had a work load to keep me thinking.
Only two beers Danny? Barely damps the dust in the barrel. I Do appreciate your offer Danny. Cheers!

Lol, no sir, I’ll buy beer all weekend. I can afford you lol

and I hear your concerns and that matters with a chain whipping by very closely.

I appreciate you spending this time, wish I had those skills. Someday...

Well I’m not certain, but I think I might be able to run without a tensioner. No rubbing as fast as my hands can pedal. I’m sure not creating as many rpms as the motor will.

and thanks a bunch to @sportscarpat for the sprocket, hub adapter, lay back seat post and handlebars. You’re making my bike look better and you’re making it safer.

Perfecting your chain line is essential.
My H. D. will roll forward all day. Back it up 3/4 wheel rotation and the chain walks off. Rag joints suck for no adjustment.
Flyer with perfect chain line is indifferent to rolling direction.
If your chain feeds with out flaw forward or backward, yer good. Maybe not perfect but good enough.
Tensioners are not needed with Diamond brand chain.
Tensioners for POS 415 yes.

Thanks Tom, I’ll get her off the stand tomorrow and roll both ways to see what happens. I do feel the chain needs to be tighter. Plus it’s gonna stretch.

These bars from Pat are incredible. I’ve narrowed them a bit, and they look more proportionate on the bike now. And if I want to take this from a BTR to a regular motorcycle, it’s about five screws and I can turn the handlebars up right. I should be able to do that without removing any cables also. Maybe some minor adjustments
