"now back to business...you DID purchase or have the third lock which comes with ya bike and it IS keyed the same as the side bags and ignition 
...if not, GET ON IT and report back here that it's done..." :yahoo:
Done, the lock was in the bag-o-goodies under the seat. It took a little "finangleing"(look that one up) to get the yamaha lock in the honda hole, but I won in the end
I am at my shop(work) right now, and am in the process of making some brackets that will slide in under the rear plastic, and sandwich between the front mount holes in my mount and the subframe. They will extend forward to the front mount hole on the grab bar. All under the seat...Using .125 high carbon steel for these so they shoud be very strong. If it works like I think It will, it should relieve some of the stress on the rearmost part of the subframe...We'll see???

O, Woe is me!!
Ya know, I'm looking at this again, and obviously the stock rack is in place, but I had assumed that its rear attachments (the two bolts where it drops through the bodywork, not the bolt in the center of the flat part) had been removed for your bracket. That may have been a completely invalid assumption, and if that is the case, I need to apologize for causing such a stir.
If all five of the rack's bolts are still in place, then the grab rails are still in the picture, and will act to prevent the rear bulkhead from torqueing outwards at the top, which is the cause of the cracks we've seen on other bikes. What cracks the subframe is not so much the weight itself, as the flex cause by the weight hanging over the end of the subframe. The rails prevent that flex.
This is a case on my part of not seeing the forest through the trees, because if you didn't mess with the rack's attachments, all the shit I gave you about messing it up is just that: shit. :huh:
I'm gonna go hang my head somewhere now. I'm just glad nobody lives close enough to come kick my ass before I get myself armed and ready.
Mike, if anybody asks you where I live, you don't know! OK?

Oh quit beatin' yourself up over this. What you did was what you felt was the right thing to do, and I appreciate it! Whether I needed it or not, I now have a substantial brace system in place that ties it all together in ADDITION to the rear rack. All nice and neat, under the seat. Will get pics up tomorrow, or maybe later tonight. It's not "purdy", but I'm betting on it doing it's job.
And seriously, Wfooshee, I appreciate your concern and input, Thank you all.

Ok, this is what I did...
Made a bracket template out of carboard, transfered it to a .125 inch carbon steel plate, cut it out and bent to shape.
Installed one bracket on each side to connect the front Yamaha rack mounts to my mounts front holes, which are connected to the rear rack mount by way of my mount.
The back of these brackets is sandwiched between my mount and the subframe, which should relieve most of the stress put on the subframe. As you can see, I still have the entire rear rack in place.
Now, before I get all happy and call it done, some of you engineer fellas look it over and see what you think.

The true test will be how it performs on a daily basis.
Keep us informed.

Yeah, I know, I stole it from your "drawing". Now making it clear the rear seat supports, that's a whole "nuther thang."
Again, thanks go to you, and the others that have helped out here.

I'm no structural engineer, but that looks pretty damn awesome!! Nice work.

Well, thanks to those that commented on this last "fix", I hope it is without flaws. It would be nice if a few more looked it over and pointed out anything we may have missed...

cummon ya quack...time for a real life test so you can put it to rest :clapping:
fill up that trunk with bricks to the brim...as many as it'll hold
now go for a 100 mile ride...make room for some patched, unfinished, old, and knarley stretches :blink:
when ya pull into your driveway, if the trunks still there, ya halfway there
now tie a rope to the trunk with the bike under a tree (leaving the bricks on board - optional),
and hoist the back tire off the ground just by the trunk
go inside for a sandwhich and brew...watch an episode of Oprah or Dr Phil <_<
if the back wheel is still in the air, project success
have another brew and pat yourself on the back with the other hand :yahoo:
just sayin'
sheeeesh; gotta hold some people's hand around here :yahoo:
