So... this thing span a bearing and completely buggered the engine.
So we eventually found a recently reconditioned 1600cc motor locally for a decent price. Half hour later she was back up and running again.
Now that dad has set the new engine up, i cant believe how much more powerful it feels compared to the old one, it sounds louder, sounds stronger, pulls like its never pulled before and throws huge flames out on command.
No rattles, knocks, and for the 1st time ever no oil leaks!!!
Reallt happy, and its a proper laugh to drive now.
Also made up a removable Bike rack.
Future plans are to fit 'all red' rear lights, extend the roll cage to the front, and buy / make some manifolds so we can fit the twin carb setup we have waiting to go on
