when was the last time you had your car tuned-up? changed spark plugs and air filter?

Kasenklaud,

Can you check your RPM vs speed, lets say when your on your 5th gear already? My Revo does 100kph at 3000rpm (5th gear). Do you experience delay in acceleration? One factor could be a "Sliding Clutch". You kept on pressing the accelerator but the speed seem to pick-up very slowly, or even non at all. There are actually many faults on the humming sound, care to elaborate more? When you say you had the tune-up, what was exactly done? Things replaced?
