低走行8000キロの激遅スクーター?レッツ4(整備で速くなりました)The valve was ridiculous

I have a low-mileage Let's 4 with only 8000 km on it. It was slow in the last race, so I had it serviced... When I took it apart, I was surprised to find that the valve was open. Would replacing the valve make it faster? I took it for a run later and it was so much faster! What a difference! LOL #Let's4Maintenance #ReasonForLet's4SlownessFound #ItWasAnyWayItToo... #Maintenance #Race #Let's4 #Let'sSquadron #ValveReplacement #SeatCut It's a scooter with a low mileage, but the inside of the engine was bad. This scooter is a low-mileage scooter, so I'm going to have to replace it.
