KYMCO MXU 270 Service Specs: Part Numbers and Intervals
Michal B., KYMCO parts specialistThis is the service sheet for the KYMCO MXU 270 (4-stroke single, 270 cc, carburetted, automatic with reverse, shaft drive). It lists the battery, spark plug, filters, belt and the rest, each figure with the genuine KYMCO part number for the model years in our catalog (2016, 2019-2021) and the diagram the part is drawn on. The figures are KYMCO service data from the KYMCO MXU 300 service manual (model LA60, 270 cc). Covers the carburetted MXU 270 (LA60J). The fuel-injected MXU 270i is a different engine and is not covered. When this page and your own manual disagree, the manual wins.
What to know before you order
The MXU 270 on this sheet is the carburetted model LA60J; the MXU 270i is fuel injected and different. It is shaft driven, so instead of a chain it has gearbox and final drive oil to change every 2,000 km or 12 months. KYMCO specifies SAE 10W-30 for the engine, 1.4 L at a change with a full-flow filter and strainer, and a DPR7EA-9 plug gapped 0.8 to 0.9 mm.

MXU 270 maintenance intervals
Whichever comes first, distance or time. The first service is the one riders skip and the one that matters most on a new or rebuilt engine.
| Item | Interval |
|---|---|
| Engine oil and strainer | at 150 km (90 mi), then every 1,000 km (600 mi) or 6 months |
| Transmission and final drive oil | replace every 2,000 km (1,250 mi) or 12 months |
| Drive belt | check every 2,000 km (1,250 mi) or 12 months |
| Air filters | clean every 20-40 hours of riding |
| Spark plug, valves | every 1,000 km (600 mi) or 6 months |
Torque for the parts you replace
Clean, dry threads unless the row says otherwise. Aluminium cases strip long before a steel bolt complains, so use a torque wrench on the drain bolt and the plug.
| Fastener | N·m | ft-lb |
|---|---|---|
| Spark plug | 18 | 13 |
| Engine oil drain plug | 25 | 18 |
| Oil strainer screen cap | 15 | 11 |
| Transmission fill and drain bolts | 20 | 14 |
| Drive face nut | 93 | 69 |
| Wheel nuts | 44 | 33 |
| Brake caliper mounting bolts | 31 | 23 |

Which model year do I have?
The year decides which number is yours where a row lists more than one. Decode your VIN with the VIN lookup, or read the model code on the frame plate, then open that year's diagrams from the model list.
