I started to design my mid mount foot controls. I have read many threads from guys on here that have done it, and from mid mount to rear mount, they are all different. I picked up an extra set of battery box mount brackets with the intent of following along someone else's idea of straightening them and bolting them to the outside of the frame. I decided I didn't want to do that (being lazy I guess), and mocked up a way to use them in their original shape. I will get extended length hardware and back those bolts with lock nuts to hold them in place. I used the natural saddle feature in the bend to weld a round tube to them. This is just the first mock up. It may change.

Every twenty minute job is a stripped thread away from being a three day ordeal.

The swing arm won't move much more downward, and the brake linkage will have to be redesigned anyway.

Next up is to design the shape of those plates. Here is previous shot of the foot pegs after bead blasting.

Sure looks like the chain is gonna hit the mount when the shocks compress. And slap it while you ride, under power the top of the chain is tight, and the bottom jumps up and down,,,, alot.
When you back off and weight shifts to the front the chain will slap on top of the swingarm. Think about a piece of teflon or nylon on top of the swingarm to quiet it down.

I am hoping the tube is close enough to the countershaft sprocket to avoid contact. We will see. The majority of the chain travel on the bottom is at the mid point between the two sprockets. The closer to either sprocket, the less the travel. You may be right, but there is limited room to fab in a foot peg mount. I will make it fit without hitting one way or the other!

You just need to place a jack under the engine.

You have a motor mount bolt just behind your kickstand to work with. And I drilled and tapped a 8mm threaded hole in the end of the swingarm pivot bolt for a step,(with all my luggage I can't swing my leg over it), you could do the same and have 2 solid mounts for the left peg.
It's your project, do what you want, but the chain slapping while you ride would be annoying.

I appreciate all the input. As I mentioned, this is just a mock up, and the first one at that. I was planning on cycling the suspension - I was going to compress the rear suspension using ratchet tie downs with the shocks in place. If I remove the shocks I won't know where they bottom out in the swing arm travel. I would like to see where the swing arm stops when there is no more shock travel. Another option for more room would be to change the tubing to .75" od x .12" wall. That would buy an additional .125" on top and on the bottom. This is all experimentation at this point. Final welding will happen only after all issues are dealt with. Tacks are easily cut.
