The victim was robbed for this to transmit load back up towards steering neck this area is a bit of a concern, it really looks like the tube I have the lower shock mount on is a little undersized closer and I am thinking of robbing the bicycle of a little more chromemoly and putting in some braces where I have the bolt taped (on both sides)

I replaced that tube on mine as well.
Put in a piece of 1" .1875 wall tube. You will get a lot of stress at that point you want something really solid there.

So far I just braced that area and am wondering if I should bring 2 more down from the top I also built and tacked in the rear brake stay.... I am taking it in to have it all tig welded as I only have a mig and am no pro Got some time to try the powder coat and was really pleased with the results.

Shake and Bake! ;D Looks like you are on the right track Bake. A good rule of thumb for any space frame is 1st choice to keep the members on tension, 2nd choice is to keep the members in compression and the least effective route is to have them in bending. Tension is the best because there is no fear of the member buckling in compression... This can be counteracted by using heavier gage tubing but lighter is better, right bending is the worst because it is the weakest direction for the tube or plate. The upper mount plate you have is in bending so the tube you put toward the headstock is a good move. I'd add 2 more members that go be to either side of the frame rails by the cross member to make a tripod. The lower member looks like it will be in torsion, so your gussets are a good thing and probably good as is, unless you want to add 2 more up toward the swinger area. Looks like you have a cool project on the go and I'm looking forward in seeing the finihed product!

A little more lower bracing, not positive the one on the sprocket side can stay, I need the machine shop to get my sprocket finished to tell More upper bracing, bad angle for this photo And more powder coating, I dont need the bracket that holds the fuse and just did it as a practice piece, so if you need one I will be happy to give it to you.... pm me an address.

Been real cold here and have to force myself out to the garage, lots of evenings out with the season and all but I did manage some quality time this morning and made some adjust steering stops. I have a few days off and hope for some build time during the week.

2 steps forward 1 step back, I had to take out the upper shock support tube because it was right smack in the center of where the fuel petcock sat.... duh. So today I reworked the area and put the support tube at a steeper angle and made a gas tank mount off the new support. Managed to get the points cam off the crank and tomorow I will take a stab at removing the rotor

Finally got the rotor and points cam off the crank and am wondering if this crank is worth sending out for rebuilding, look at the rust on the seal surface.

Those crank seal collars are replaceable. Talk to Larry at Redline Motorsports, check out their product page. www.redlinemotorsports.net/

Or you can have the collar machined down smooth and just go to your local seal and bearing shop and have them give you a seal with the correct ID of the machined down collar. The can get you seals in .5mm incriments.

I managed to chuck it in the drill press and emery cloth to a nice finish but I'd bet it's a tad undersized now.

More progress..... wanted to run high fat bars, like the Ducati Monster so the top tripple got drilled out to accept a set of Renthal bar clamps It's been a huge effort to run that 180 back tire but I am close... infact it's a definate maybe. The 520 motocross extra narrow xring chain is really helping. From below and above The suspension is now all apart so I can powder coat and it's starting to feel like I may be going somewhere.

Still have some frame work but wanted a break from it so I worked on getting the ignition switch mounted in the GSXR triple....some mods necessary a little cutting and fitting, aluminum welding to take place tomorrow but this should be the finished product, maybe I can find a O ring to fill that little bit of space. Next was to tear the rear brake calipers apart for powder coating where I was rewarded with this glick Glad I took them apart, not sure if I am going to buy rebuild kits or not yet... they looked pretty good inside despite the goo. Odd set up on the Suzuki, 2 pucks per caliper, 1 large and 1 smaller... strange. Now I have all this stuff ready to take to my buddys blaster so I can start coating... that is the shop oven lads
