In an effort to save my already powder coated frame (purchased that way) I wrapped the frame in tinfoil to help prevent as much "pocking" as possible. Since welding involves molten metal it often leaves "Pock marks," little extra bits of molten metal that spark out and bind to areas you don't intend.
Frame Modification phase two: Welding. So I got some help from fellow bandits to help up the newly prepared piece. Here it is welded up nicely.
Then we cut inside frame out to create the pocket for the simo engine's large fins. Since it doesn't have fans on the flywheel it needs these large fins to cool the engine instead. While a lot of people cut them off to get them to fit, most then have cooling issues. I wanted to preserve these as best I could.
After mounting the engine it took a series of measuring, marking and cutting to get to fit just right. Here you can see that I had to cut further material to allow for the side intake to be mounted post engine mounting.
Here's the complete mount with engine, side intake and carb.
