Which bike did you buy it for Jack???
Just like the engine oil, I'm sure Trumpet have cornered the market and ensured 'one-fit's-all' sort of thing ain't going to apply to the R3 :twisted: I know with my FJR1300 that some patent filters will leak under pressure.
I hope our resident expert - Hombre - will be able to put us right about resistance/pressure and all the teckie stuff...
