You have a bunch of good bracing in there.  I would think the one from the subframe to the arched backbone would be overkill at this point.  Unless you go all Evel Knievel with it.

I mounted a road rider on the rear wheel, and dropped the bike off at my buddies shop. I just made him a seat for his BMW project, so for trades he is going to make me some wheel/swingarm spacers, and help me finish the swingarm fabrication. Cant wait to see the swingarm finished! heres a pic of his beemer.

My buddy had some time to turn up the wheel spacers. The swingarm is a perfect fit in the the 750 twin frame, nothing needed there. While he was messing around with that i used his buffer to polish up the new engine covers. I personally prefer the older style text, and since the ones on this motor are pretty trashed its was a good excuse to switch.

I whittled down the shock mounts. Eric hogged out the axle plate and welded them in. the torque link mount is welded in as well, as are the chain guard mounts. We had to cut a chunk out of the gusset in the middle to provide clearance for the wheel since the arm was shorted and inch and a half. I hope to have some free time on sunday to go back and polish the swingarm out on his buffer, figure out the chain slider situation, and get some good pics of it in the sun.  Once i get it home i am going to measure the geometry, and reevaluate. I may need to swap for different triple or move the upper shock mounts. we will see. I'm stoked!

i noticed when i was buffing the stator cover that part of the casting was broken off, not surprising since it looked like someone beat on it with a hammer at some point. I welded it up and started to polish it out. I also brought the bike home form my buddies shop. I didn't have time to buff out the swingarm yet. I couldn't resist and mocked it up real quick... things are taking shape  8)
