Just compressing the shocks with the tie downs told the story.  You guys were right, the chain will hit under full compression.  That natural position in the bend of the brackets was just a bit too convenient.  I will start looking at some of the other ideas/options.  The whole reason to just tack things and check them out thoroughly before going hog wild and welding it all up on the bench...

With the chain conversion there isn't much room between the frame and the chain to add plates on the outside using the battery mount bracket bolt locations.

You have the one motor mount bolt to work with. If you don't want to mess with the swingarm pivot bolt, you can weld a lug onto the rear of the curve of the frame. Those two spots will give you plenty of support. Some guys shy away from welding on the frame, but you already moved your kickstand,,,,,,so,,,,welding a lug should be a piece of cake.
The muffler support bracket would need to be braced alot, it is not made to carry the weight of a rider standing on the pegs. Whatever you do, test it by jumping up and down on each peg before ever riding it.

Duplicating the tab on the right side, that is used to mount the muffler brace bracket, on the left side sounds like a good starting point.

I haven't been successful in finding a good picture of the RYCA foot control bracket.  I would definitely like to see how they were doing it.

nerdsport did a cool build and did his own take on a RYCA bracket.  He used the factory pedals on his but I think he might have had a high pipe.


EDIT:  LOL, both of those pictures were contained in this thread.

Oh, looky, looky!!!  I finally scored the exhaust I was looking for.  It showed up today.  An unused Mac Performance exhaust.  All of the clamps and bracketry came with it.  Another piece of the puzzle.  As soon as the piston comes in, the top end machine work will commence.   This baby's gonna breathe!
