Keep an eye on the spark plug , see if it turns brown because “pure white” isn’t good long term, it suggests overheating soon due to low fuel at high revs / high loads or the sparking system stops firing every now and then when it gets hot (but then if it stopped firing, plugs would be very sooty wet with unburnt fuel)
Keep an eye on the injector and fuel pump!
