Very much looking forward to seeing the finished bike. Looking awesome so far.

Haha, no those are all my bosses from car shows in the past. I only have one from my My katana I put in a show once.

Love the face shield.......dare I even ask where you got that from.....

ohh ya and the bike is nice....I guess it's chained up so it don't go anywhere.....attempt at humor....

I would have it chained up as well, wouldn't want some one to take a walk with it...

[brslk]

That's pretty cool. I'm surprised I have never seen you around town with that helmet and bike before.
Just a guess but from the pic I would say you live south of WEM?

The mask my boss airbrushed on that perforated vinyl that goes on windows of vehicles.

I actually sold the bike a few years ago when I bought my truck. Didn't like having a bike payment either. Sold the helmet awhile after that too. I will probably do another shield though. Got a lot of people turning around at stop lights to look at it.

gsxr rear sets mocked up. Just need to make a plate to bolt up the top mount.

Absolutely AWESOME amount of design, fab work and build progress in a VERY short amount of time. I'm jealous of your skill and phys. ability (I'm old/broken)
I was curious what year the rear sets are from, and what you did for the link mounting on the center stand mounts. Did you use the stock tabs, or did you fab up something STRONG???

(From April 2011)

I took a test ride yesterday (200 mi.) to see how the motor was gonna handle some hours on the highway, since I've only been able to take it on short rides since I got this pile, and the good news is she ran like a champ!!

I knew I needed to raise the ride height, as the new 4-1 header hits on big bumps. I just came in from looking at how hard it hit, and found the frame is cracked almost completely in half where the lower tubes sweep up, just past the back of the motor!!

The previous owner, who put the '89 GSXR 1100 swingarm and monoshock set up on it, used the mounts for the center stand as the mounting point for the pivot arm that attaches to the shock and the bars that link the swinger to the pivot arm.

The tube that those mounts are on attaches to both lower tubes of the frame, and the forces the suspension place on it caused it to literally tear almost completely off the lower tubes, taking a good portion of the frame tube with it

I feel lucky to be alive, cause I wasn't going easy on the old gal, and thought she felt kinda funny the last 30 mi. or so, but I thought it was just fatigue and my bad back screwing with me. Now I know it wasn't my back

Any input you can provide would help me in fixing this issue so I can get back on 2 wheels for a while, before I'm too crippled to ride anymore.

Thanks, Eric

IMPRESIVE!!

I'm not sure on the rear sets. My buddy had them and I think it is an 08 gsxr that he has. As for the center stand mounts that I used. I left them there but added more plates for strength. Will be inspecting all the mounting points regularly just to make sure nothing is cracking or moving.

Wish my GS's prior owner built as solid as yours.

I got a good look at just how bad the cracks are on my '82 GS1100E's frame today.

Well, I've been wanting to address all the rust and un-tidiness on this adopted-abortion, guess now's my chance, since I gotta tear it down to fix my frame.
Def. keep an eye on the mount points.

WOW! those are some serious cracks.
Unless you are proficient at welding or have a friend that is that will work for beer I would be looking for a replacement frame.

[Erki]

Wow that its scary. Will keep an eye on that area. Maybe add something around that cross bar for added strength. A gusset or two.

[elcornus]

I'm going to surgically cut/graft a section of an '80 1100 frame into the cracked '82 frame.
A close friend has a Hot Rod shop (first pic) in my town, and is going to provide any/all welding, access to shop space and machine shop (I'm a disabled machinist).
It's going to take me a while to get this accomplished, I will prob. have some help from chef1366, who's offered to ride up from Santa Barbara on occasion to assist.
THANKS Chef!!!

I will be taking lots of pics and starting a thread on it, so we can get back to Erkis build.
I just wanted to point out the weakness of the center stand mounts on this type of set-up.

Now, onto THIS build!!

[Erki]

Well its been about a month since any work was done to this old girl but I'm back at er. Had a headache tonight but still managed to get my tail light mounted roughly.
