Complaint

Ticking noises from the cylinder head

Cause

Due to quality differences in the adhesion of the DLC (Diamond like coating) of the

rocker arm, the rocker arms and camshafts can wear prematurely.

This presents itself initially as ticking noises from the cylinder head.

Measure

All the K46/13 (S1000RR's) manufactured since 1/16/2018 are being fitted with a new

version rocker arms. The other models, including the K8x (F850/750GS), will still be

temporarily manufactured with the previous version rocker arms and converted gradually.

The coating of the new lever has additional layers, which have a damping effect and

increase the robustness of the layers. Visually the new rocker arms differ considerably

from the old ones, see attached image.

If the only complaint of the vehicle is ticking noises and the motor is not damaged
apart from worn rocker arms and camshafts, ALL rocker arms and camshafts will

be replaced and an oil and oil filter change carried out.

ATTENTION. Always check both cylinders in the K5x (R1200's) and ALWAYS replace

all 8 rocker arms, even if all rocker arms do not show traces of wear!

until further notice, continue to install the original rocker arms in all KO2 (G310R),

KO03 (G310GS), K5x (R1200's) and K8x (F850/750GS) motorcycles.

For all S-models (K46, K46/11, K46/12, K46/13, K47, K47/11, and K49) in a repair
case, the new version rocker arms are to be installed. Also exchange ALL 16 rocker

arms and both camshafts, engine oil and oil filter).

Order the following part number for the S-model rocker arms: 11 33 8 389 397.

The part numbers cannot be found in the EPC until the update in May 2018.

If problems re-occur with the new rocker arms, please inform us immediately using

a PuMA case with informative photos, in which the batch numbers of the rocker arms

(see attachment for batch number location) and the complaints are visible.

Only for reimbursement under guaranteed goodwill instances (after expiration of vehicle

and parts warranty), please use only the defect number "11 33 00 28 rocker arm /

rocker arm worn".
