Well, i did it! I took a perfectly good frame and welded the piss out of it!! Here's an up-date: I gusseted the rear shock tower using 1" square tubing (just like Kevin's photos) and i also added another flange where the left sub-frame strut attaches to the main-frame
Another gusset was welded into place near the steering head, connecting the main backbone to...well, look at the photos of Kevin's bike in the link above, it easier than explaining. Now here comes the good part...i welded a large gusset between the left footpeg and the frame, therefor providing me with a solid pickpoint to attach a bar to the back of my previously fabricated CrMo sub-frame
This will provide ample strength and use of the stock muffler.
Thanx for all your help everyone!
