It's past time to start XS2 Resurrection

[TwoManyXS1Bs]

I had to flip your pics upright, unconfused.

Viewing rearward, the 1st pic shows the "break" on the right, brake side.

Viewing forward, the 2nd pic shows the "break" on the left, drivechain side.

Huh? What gives? 2 breaks? 1 break spanning under the downtube?

 

[GLJ]

Both sides broke.

 

[TwoManyXS1Bs]

My plan is no matter how I fix it I'll bolt the engine case into the frame before tack welding the fix.
The swing arm a different challenge...

Also, strongly recommend fitting a spacer of appropriate length between the swingarm bungs.

 

[GLJ]

Broke on both sides of downtube.

 

[GLJ]

Already thought about that. Put in swingarm tube in during weld. Should give me correct dimensions. Going to use brass bushings for swingarm. Add shims or machine as necessary.

IIRC and I'll look tomorrow I think the later frames went to an oval or built up tube across there instead of just one lightweight tube. 73 to 74 saw a substantial upgrade, stiffening and reinforcement of about the whole frame.

 

[GLJ]

Cool thanks Gary.

All of this, has me thinking I need to give my XS2 frame a good look over. Nows the time, it’s just a bare frame sitting on my garage floor.

 

[GLJ]

I was going to ask you to see if you have the same offset that I have have. To make you feel better I looked at my other 72 and the frame is not broke. Since it's still in one piece it's not easy to check for offset.

I’ll try and get some photos tomorrow!

 

[GLJ]

Used many different welders during different times. What do you guys suggest?

Harbor Freight MIG 170 works great for the price, change the ground clamp.

a bit blurry but that it got bigger is evident.

Yo-mama we had a weak spot...
Was going to make an engine stand out of this but it's very low priority, could slice out and ship the cross brace...

 

[GLJ]

Gary
Thanks. I'll keep it in mind.

 

[GLJ]

Interesting what year is that frame?

Gary, what exactly are we seeing in your photographs? I’m not home right now to compare with mine. Has that one of yours been beefed up?

Who knows? but most likely a late special.

Nope all Jenn you whine Yo-mamaha, after the big frame beef up in 74

Those certainly look like quality factory welds! Ha!
That’s very interesting, that says to me that frame breakage in that location wasn’t a rare occurrence. I’m going to have to think about this.
