Bogging down and a touch smokey!

Also, I think modern 4 cyl bikes are a bit more sensitive than twins to such damage - perhaps built to finer tolerances. Just been reading Ted Simon's wonderful book Jupiter's Travels - the damage his old Triumph was able to sustain and continue running with is amazing - I don't think modern bikes could do that. And now someone will prove me quite wrong (I hope!).
