'Weak point' on 1980 XS11 Frame??

[Incubus]

If you best friend is here, let me know when you drive into town. You, me and Webbcraft can get together for a ride. There's some pretty roads out in the Hill Country.

sounds good

that's quite a trip for the Blue Streak, maybe I will put some more miles on the FD swap?

About six hours from The City to Austin. My folks used to live in Shawnee and I used to live in Belton, about 60 miles north of here. With 55 mph limits, that trip took about six hours. You might could shave some time from that now.

I would tie together the triangle just above the swingarm pivot.
Using same diameter tubes with .065" wall. I would weld tubes horizonatally (total of 3 extra) that form a rectangle around the battery box at the same level as the existing one in forward part of battery box floor. Phew that's a lot of words and nobody probably gets it anyway? Next would be to reinforce the steering head and front down tubes and cross braces under the engine. The swingarm could also be braced, but with light weight tubing. The main problem I see is the the basic cradle has such a large open area that it's going to flex a lot. I converted to solid motor mounts to tighten up the frame bit. But it's still not using the engine as a stressed member so results are going to be limited. I don't carry heavy weights for touring so I don't worry much about the rear subframe.

solid mounts

my rear solid mounts are finished and will use those and keep the front upper/lower rubber to take out the vibes....chop
