after naffing about with the standard screen , all positions, tilting using spacers , mirror extenders,thought of getting the dremel to it to shorten it as I've read this can work for some, took it off today no buffeting but very noisy so rather than buying every screen available I'm going for the rated airflow however the kappa is slightly cheaper than the givi , am I right that both are operated by the same family so are exactly the same product?
