About Yamaha XJ900 parts
Confirm the exact XJ900 model and year for each service part.
Repair choices by model, year and component
Yamaha dates the original XJ900 to 1983. Its 1983 XJ900RK (SECA) carburetor fiche numbers assemblies 1–4; the later XJ900S Diversion is a separate branch. Match the full designation and the year on each repair item.
Carburetor rebuild
For the 1983 XJ900RK (SECA), Yamaha’s carburetor fiche numbers assemblies 1–4. The carburetor rebuild kit (SKU 48-1938) is listed for XJ900 (1983–84) and sold as one kit per carburetor; a full matching four-carb bank takes four kits. Confirm the fitted bank and compare kit contents before ordering.
Fork oil seals
For XJ900R (1983), fork oil seal SKU 27-1012 carries a 37 × 49 × 8 specification and is sold as a set of two. Match the dimensions and fitted fork before ordering.
Valve-clearance service
The valve shim kit (SKU 73-0173) is listed for XJ900 (1983–85) and sold as a kit. Measure the clearance and check the shim specification against the service procedure before ordering.
Choosing parts for Yamaha XJ900
Match the complete model: the XJ900, XJ900R/SECA and XJ900S Diversion names refer to distinct catalog applications. Yamaha’s 1983 U.S. parts catalog identifies the XJ900RK (SECA) 35H; later Yamaha material identifies the XJ900S Diversion separately.
Use each item’s own years: the carburetor kit lists XJ900 (1983–84), the fork oil seal set lists XJ900R (1983), and the shim kit lists XJ900 (1983–85). These item ranges do not define every year or variant in the collection.
Check what is fitted: before carburetor or fork work, compare the motorcycle’s model marking and the installed component with the product application. For the rebuild kit, allow one kit per carburetor being serviced; do not infer a total kit quantity from the collection name.
