Couldn't give a toss about the post count and I've got too many cuts, bruises and headaches to be classed as an armchair expert. I speak from knowledge and regret. In the mid nineties I had a mint Honda CB250N which I dropped at around four mph on ice at a junction. When I picked up the bike I had a broken indicator and a loose baffle on my left silencer. I replaced the indicator and thinking I could live with a little rattle (and without the cost of replacing the silencer) I left it. Fast forward four months driving home from work and a max of 15 mph at 9000rpm in second all the way home. Took the head off to find a half moon burnt out of the left pot exhaust valve. It cost me a fortune for an exhaust valve and gaskets, an expensive lesson never forgotten.
