I saw this on Craigslist today and didn't know whether to laugh or cry. I'm pretty sure this is the first time in history this modification been done successfully. All other attempts failed! Maybe it was done for gas mileage. Maybe it was done for safety. We'll never know! What I do know is this Yamaha went from 25 H.P. to 5 H.P. INSTANTLY.  In a trailblazing move, plumbing drain pipe was used successfully for an exhaust system. Be sure to slather on the pipe dope so you don't get any leaks! The craftsmanship on the heat shield is second to none! Obviously, someone has put a lot of thought and work into this project. To what end- I'm not sure. Enjoy, it won't last long.

Now i need to know more. Any link please to craigslist.

There isn't much more, but here it is-

Un-believable, I'm lost for words, certainly someone will save that poor bike....

Right there with it, posted this in sightings last week. Amazingly someone bought it!

I tried really hard to see what was going on with this 360, but, I can't see it?!? Old allergy eyes....

What's in the frame?

I know Rathdrum a little bit, whatever happened makes some sense to me...

Is it a rotary motor driving to the left side crank. Man we need to know more. Love creations like this.

Tip- You can use control + to increase the size of an image (or text) on most browsers. Control - (Or control 0 [zero]) to return to 100%. Rathdrum, Idaho is a very unique place, for sure. There is a great little burger joint there- Penny's Pit. Good food.
