So after the Parys trip i did notice some light dust color in the airbox and that was with a unifilter and lots of grease. After close inspection you can clearly see that the plastic top part "lid" bowing in the centre so i made this 2mm steel flange to keep it from bending. Will see if it helps.
I'm a brand new owner of a second-hand 690, having reluctantly sold my 990 in favour of something more maneuverable.
I am astounded by the poor design and quality of the airbox on the 690. In fact, in general, by comparison with the 990, there's a distinct whiff of curry in the air. The 990 is built and runs like a Rolls Royce.
Anyway, c' est la vie. MXDURO, please can you put me on your list of those needing one of your elegant steel brackets.
Merci
