## 🛠️ Service Notes

-   Listed as the Stage 2 and Tier 2 standard version for engines from serial number 5301077757 onwards - emissions stage and serial number must both match
-   Building up a crankcase is a full engine rebuild, so plan for bearings, seals, gaskets and a machine-shop check of the bores
-   At 229.5 kg this needs lifting equipment and freight handling rather than a parcel carrier
