How to install a 4 stroke motor on my weird shaped frame bike frame.

So I have this mini chopper bicycle frame that i want to put a 4-stroke motor on it.
The problem is that the frame in the center is too long and some of the bars are oval shaped!!
Any ideas on how to get a 4-stroke motor to fit?

I had to build a custom engine mount for my micargi rover, all the factory 1's were too short to reach from frame tube to frame tube. More than likely you are going to have to fabricate a engine mount for whatever particular 4 stroke engine you are wanting to use on your bike.

Yeah I figured I'd have to weld a frame bar closer to the front of the frame..or cut off the bar in front of the seat and scoot it up..

I just got to thinking, you could buy a stick or 2 of this angle iron, a box of 5/16" bolts nuts & washers & bolt everything together to make a mount.
