Re: what did you do to your motor bike today?
Maybe you can use some of the ideas for spreading the frame for a little extra space as many have shown on this site. I know there is controversy with this approach in some ways, but if cutting, re-welding and making a "Z" shape I can't see that as a problem. The time and effort is the thing.
Kudos to you for helping your friend. I helped out a little yesterday holding onto a friends windsurf board and mine too, while he retrieved a kite surfers board that was going out with the tide. The wind was flukey and the water was nippy a bit, but the sun was shining.
