Just remembered this story of my youth, back in the 70s and one of our mates we grew up with was a surfy sort of guy, loved the coast life style he only lived around the corner and a few streets away and we were all getting into dirt bikes and Vince wanted to join the dirt bike craze, he brough a Suzie TS 400 motor crosser for $400, it was a weapon and to much for Vince, but he only had it for a few days when the motor seized up, lock tight, he pulled one side case of but gave up was just too much for his salt water effected brain, so I said big money to fix and offered to take it off his hands for $100 and he took it so I pushed it home and that side case he took off was just screwed back on loosely, so I decided to take the other side case off the motor and behold what I found, the crank nut had come lose and caused the crank to get misaligned and jammed into the front crank case, I just tighten up the crank nut and the crank came back to where it suppose to be and the motor turned freely again.
Well I put both side case back on and fired it up, but I couldn't resist the temptation and next thing I was doing a wheelie past Vince's place, it was a very powerful and fast motor crosser and Vince came running out side when I came back past on the back wheel and giving Vince a cheeky wave as I went past him, he was stunned with only selling the bike to me within less than an hour before, I kept going and didn't stop to rub it in, as being a very loud bike I just wanted to get back home before someone called the cops, but within 5 minutes Vince was around asking how I fixed it, and I told him if he had pulled the other side cover off he would have seen the lose crank nut and man did I rub it in, I sold the bike next day for $400.
