Custom motor mounts welded to frame?

Skyhawk frames have a pedestal mount for mounting 2 stroke China Girls and they crack at the weld where it's mounted. Aluminum frame. Chinese made.

Thats because they're poorly welded. Several members here have welded mounts for several different types of engines. With the morini engines, you almost have to weld the motor mounts on, and it's certainly better if you do. Same with the 212 Predators. And if you really think about it, on motorcycles they aren't simply welded on, but actually structurally part of the frame as well. So no, it's not a bad idea in fact it's a very good one. Personally I think the reason the skyhawk frames fail is because the Chinese worker who make the frames are not very well trained in the techniques needed to weld aluminum. Its a bit different than welding steel, and then you need to properly heat treat the material you've welded as well and I don't think they do that either. Even some bikes sold at Walmart are not properly welded sometimes. In short, welding motor mounts on is a great idea if you do it right.
