Just got back from Spain & France and as most of you know, as you get further North in France, the roads get straighter. On one particular long straight road, my mate, on a Z H2, and I decided to have a 'play'. He has a particularly noisy end can, even with DB killer in it. 10 mins later we were joined by 2 police bikers! Luckily they caught up with us whilst going through a village and we always slow down for villages. They followed us for about 10 mins and then went by, waved to follow them and then made of making 'very good progress'. About 20 mins later they indicated to turn and we did not, so they stopped their bikes, stopped us and asked us to turn off our engines and we thought, okay, here we go for at least a telling off. But no, we had a good chat about where we were going, where we had been, etc. and then they warned us about large French farm machinery and wished us well. Anyway, the point is, we think my mates exhaust at full chat, caught their attention
