if you disagree or think what im posting is hogwash, dont blame me im just the messenger and passing on info ive collected . anyways i been calling welding/fab shops about what it will cost to do the welding on a chassis. $100-$200 will get the job done so that seemed cool . also i asked about treating the metal, not one place said treating it would be necessary. so i called a few more places and talked to a guy that said he welded on factory recalled/defect bikes form honda and suzuki, aparently the dealer/factory has him do the welding if theres some sort of problem.....anyways, he said the factory guidelines that he goes by does NOT require any treating of the aluminum before or after welding. me not being knowledgable in the alloy field i was curious to all the talk about normalizing, annealing, heat treating etc., then i got thinking, out of the hundreds or thousands of conversions that have been built and not treated, how many have i seen or heard about cracking.....ive heard about 1 bike cracking. it only makes sense to me that if treating the aluminum was a big necessity then chassis would be breaking 5 days a week..... but they aint been breaking, not that ive seen or heard about anyways. if Pstoffers bike dont crack im sure nobody elses ever will

There you have it. However how many are not known and still to be determend.
But ya considering how many made have been made.
Then there's What type of riding and how skilled the rider is. As you know, the more skills then more than likly it could/will happen.
considering S/H welded 2 of those bikes, we cant rule out shitty welds, which probly have nothing to do with the metal being treated. robbie and Pstoffers had them rewelded by a professional....did they have any cracks afterwards ?

No cracks after 7 years and I had mine heat treated after being reworked.
it runs great I bumb up the main to a 210 & put a EGH-M needel in there , I dident see it get almost get smoked on the 3 runs Chance did at banchee hill

My two cents. And yes I am a fabricator. ( For now )
The weld is strong, its the material around it that will break.
Rarely will you ever see a weld break, it's the material that you are fusing
together. Meaning that it breaks next to the weld.
When you weld weld on a chassis or frame you have stresses where
you weld (pulling and pushing) from weld shrinkage and if you don't weld it in the right sequence you have constant or uneven stresses in the chassis.
It will crack in the area that has the most stress. This location is trying to hold the whole thing together.
Heat treating is letting the chassis "Relax" into a form of even pressure throughout the whole chassis. Letting it cool at a rate that will not create
uneven stresses.
One thing for you to remember you are building something that was not supposed to be done. ( Otherwise HONDA would be doing it )
Things will break, it's not bullet proof, it's a race bike it will break!
Heat treating is just a little bit of added insurance that it won't break.
But you could still have a weld that is contaminated or a weld that didn't
cool properly and that will create a crack. That's the one that will crack right down the middle of the weld.

The 210 main was killing it, chance would get me out the hole by about 3 lengths then I would slowly catch him all the way up. It should have spanked me

I think your right on the money. Im welded a 4" X 6' diameter plate into a test pile we were driving. I made 2 passes with a LN25 running .045 inersheild. Then we hit it with a 40 ton impact pile driver and the can it was welded into failed but the weld held fine. By super heating the steel it weaken'd it because the super was in a hurry and didn't want to wait to do it right. Whatever, for the minimal cost of heat treat, why not just go for it.
