After I change the front sprocket, I noticed that the bike’s sound has changed (a bit lower and not so deep). Maybe it possible because it puts more revs now, but shouldn’t it reflect only on a noise level (louder), and not on a sound?
Also, can someone explain what does it take to check/change the air filter?
Thanks.
