The affected vehicles have been marked with campaign number 0011600000 in AIR.
In order to determine if a specific motorcycle is affected by this campaign, it will be necessary to verify the
vehicle VIN in AIR (Aftersales Information Research). Based on the response of the system, either proceed
with the repair or take no further action. Please note, open campaigns or vehicle stops may not appear in
DCS Warranty Vehicle Inquiry or sales systems until 24-72 hours after they are announced, therefore AIR is
always the recommended method for determining open campaigns and vehicle stops.
SITUATION
After a quality inspection it was found that due to improper machining, the right-side chain tensioner screw
plug doesn’t meet the specifications over the service life of the motorcycle.
As a result, over increased mileage accrued noise and engine damage may occur.
For vehicles that have not yet been delivered, the service action must be completed before vehicle
handover. If the service action cannot be completed due to a parts, software, or special tool shortage, the
service action then must be performed during the next possible workshop visit when parts, software, or
special tools become available. In such instances where work cannot be performed, it is essential to inform
the customer of the situation.
In all instances in which the vehicles have already been handed over to customers, the Technical Campaign
must be carried out at the next workshop visit.
PROCEDURE
Replace only the right-side chain tensioner screw plug (not the tensioner) per the repair instructions “11 31
097 – Remove and in stall or replace timing chain tensioner on right cylinder”. Currently all associated repair
procedures are found in TIS 2.0 under supporting material for the bulletin until AIR is updated.
NOTE: The Screw plug replacement parts come with the required gasket as a set.
