It does but it is the only video I could find on the fly that showed what happens when a frame is cracked. Be good to have a better video I'll keep looking.
I did find something on this site that tells you to drill into the frame:
At the bottom of the page it says: Larger frame size requires drilling into bike frame and use the universal motor mount..
Man what terribly advice. No way no how should anyone drill into their frame period it is a huge safety issue.
Here's another site even showing pictures telling you to drill http://www.kingsmotorbikes.com/FA_Q.htm
