I'd bought a '73 RD350 that had been in storage since 1978 two years ago. 32 years in a garden shed. Brought it home and sort of checked the bikes weren't siezed, the fork seals where leaking and the tires had some checks in the sidewalls.
They need a charged battery to fire so I pulled the battery out of my snowblower and bungy corded it to the seat and wired some jumpers, poured in fresh gas and it sparked up on the fifth kick.
I took off down my subdivision court and the wheel came up going into third, it didnt want to stop at corner in the cresent and the rock hard tires slide beautifully, nearly crapped myself.
Came back up the street and my wife said, "its just here to be resold right?" , I nodded appropriately and a guy in Hamilton bought it a week later.
