I've had a few Meriden Triumphs in my time, but this one... Got a calendar at Xmas, like you do, and first pic up is titled "1970 Triumph Bonneville" Well, the side-panels and tank might be! But disc brakes?! And that;s just for starters. The engine, with that chaincase, and tappet covers, and very un-Triumph like clutch (?) It's obviously a bitsa, but anyone identify the engine?
We need the picture!!!. My dad will be able to tell you all you know. They did do they with disc brakes towards the end didn't they?
I have to admit this one is really oil tight, my other other two pre-units not so, the crank breather, the oil pressure valve on the timing cover, oil rocker feed pipes all produce misting which eventually drops on the floor, hey its British ...........
