Routine Maintenance Reference
Items to stock before you need them: Engine oil (10W-30 — change every 20 operating hours). Spark plug (NGK CM6 or equivalent — replace at 50 hours or if hard starting). Drive chain (inspect tension every 5 hours; replace when chain can be pulled more than ½ inch from the rear sprocket). Air filter (clean every 10 hours, replace annually). For the full model-specific maintenance schedule, see the FRP Answer Hub →
Fitment Note
FRP parts are matched to specific model configurations. GMB100 / GMB100P / GMB100U parts are largely cross-compatible within the 99cc family. MB40, DB003, FX40, and Sahara40 each use separate part sets. If you are unsure whether a part fits your bike, contact FRP support with your model name and purchase date before ordering.
