widening a-arms

I dont think it would be too safe but a guy who I have ridden with a couple times cut his swingarm in half and welded 2in spacers in it and it seems to hold up good.
 
I have done this to other a-arms the most important thing i discovered is to get a very thick walled tube so it can be machined down to slide inside original tube of the a-arms then i tig welded the joints

they have seen 2 seasons of mx & speedway no cracks apparent yet
 
the only way that I would ever trust it is if you sleved the new tubing to either fit over or inside of the stock swing arm tubing. I would never weld the same size tube to make extenisons. That is like haivng a death wish. Kinda like not tightening all the lung nuts on your car just to see what happens.
 
well personally i wouldn't do it even if its strong and doesn't crack, and send you flying off when it breaks it will look a bit crap.
