Oh hell i've got a few of these lol. Subframe on my old CR250 broke when ai flipped it. Used a ratchet strap to hold it together. Sold the bike, (the guy knew it was broke) with it tied up with a shoe lace.

I bought my 96 civic, with a hole in the block, i JB welded that for a week until i got paid to get my new motor. Tons of times i've held my exhaust up with coat hangers. Shift linkage in my CRX bushing was worn, so i jammed a few nuts in the bushings to take up slack until i could buy new ones (its still like that, and has almost no excessive play)

Few other things i've done too lol.
