Was the noise when on the gas or off it?
It took 17yr old three laps to work out "it aint right" and three pistons later to get it all good.
cheers A
a snippet found from superhunky;
Turning and roosting in the widening gyre
The rider cannot hear the camshaft chain;
Things fall apart; the crankshaft cannot hold;
Mere anarchy is loosed upon the world,
The oil-dimmed tide is loosed, and everywhere
The ceremony of inexpensive repair is drowned;
The best lack all conviction, while the worst mechanics
are full of passionate intensity, and drunk.
