Never seen an exhaust
riser that doesn't need cleaning
/ repair / replacement sooner or later; I suggest 1500 hours would be a very

All men dream: but not equally. Those who dream by night in the dusty recesses of their minds wake in the day to find it was vanity: but the dreamers of the day are dangereous men, for they may act their dreams with open eyes, to make it possible. T.E. Lawrence
