Hello guys, some time ago i noticed that my acceleration is ****ty. Realy, it got worse and i don't know why :yack: it seems that acceleration is slower in the 1 and 2nd gear when lifting, i mean longer to go to 6 RPM. But the worse is, when i go in 3 - 6 gear. For exsample, i go in 3rd gear in 40km/h then i accelerate to 60, and go back to 40, ride a bit longer in that speed, and hit the accelerator, and s :tsktsk: happens, it is slow and not smooth, besides sometimes i feel vibration in pedal when i push it help me guys, i am sad about that, i want to go to service, but they may say it is normal, fu :tsktsk: it is not!!! So what may be the probs? Filter(it is quite dirty), system, spark plugs?
I hope, You'll help me
