Was poking around a wreckers today looking for something else and stumbled across on of these, looks complete except for electrics. I was there at 10mins to knock off so I couldn't spend to much time looking, but the owner is allowing me to go back on Tuesday and spend as much time in the loft as i need. If anyone is chasing one of these ( as I can't imaging they are as common as a dt motor) I can check it out further and let you know anything you need.
Don't know what it's off, but looks like either a 250 or big bore.
