Service bulletin SMT-TN-164

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Balancer cooling oil jets and crankcase spares kit, motorcycle handover (corrcect the fitting of the seat(s) or seat cowl), rider's seat fitment, handlebar clamp fixings, front suspension, and rear tyre wall pattern. A new crankcase assembly has been introduced for the above models from engine number 713402. The new assembly features modifications to the crankcase castings. As as result, both front and rear balancer shaft oil cooling jets have changed from M6 to M8. The new M8 oil cooling jets are not retrofittable and parts will continue to support the old condition M6 oil cooling jets for models already in service.
