Only when I miss a gear

I didn't really plan it this way, I've got a complete dry clutch engine sat here needing a rebuild, as well as the motor in the racebike, as well as about half a dozen barrels lying around.
It's just the way it worked out, a couple of seizures, a couple of 2nd hand barrels, a couple of cold months thinking "I should get on rebuilding that really" and before you know it the season's started again.....
