I must admit, I'm a bit p*s*ed with the dealer for not advising me of this issue, seems to be a common complaint regarding the Triumph stock screens. Still I guess the moral of the story is "Before you ponce 250GBP on a screen, ask your friends at the B.A.F. for some advice first!". As we say "Lives and Learns".
Now then... who knows anything about Triumph Long Slash-Cuts ....
