Er zal vast iemand zijn met zo'n filter hier :-)
https://www.knfilters.com/mobile/recallkn204K&N has discovered that in certain KN-204 oil filters manufactured between March 1, 2016 and September 30, 2016, oil can leak at the area where a nut (intended for use to remove the oil filter during routine oil changes) was welded to the bottom of the filter canister. If there is such a leak, oil could come into contact with the rear tire or rear brake of the motorcycle on which the filter was installed. If this were to occur, it could lead to a loss of control or a crash. Therefore, K&N is offering to replace the affected oil filters at no charge. This offer of a free replacement also applies to those covered KN-204 oil filters that were purchased for use in an application other than a motorcycle, such as an ATV or PWC (personal watercraft).
