So I've had a ticking noise coming from my bike for over a year now. Every time I take it for service I'm told it's perfectly normal. Whatever. Well it hadn't been getting any worse until the past couple of weeks it's been getting faster and louder. A couple days ago it went from a distinguished "TICK...TICK...TICK" to a sound similar to a bicycle chain when you stop pedaling. Today it was closer to a buzz. Also the bike started vibrating a lot... Today's ride was just plain uncomfortable... the vibrations went up my arms and feet. The vibration stops when I hold the clutch in btw... Also it seems like its taking a lot more effort to respond to the throttle... it's not accelerating as quickly and it seems too loud. It seems hung up like when you first try to ride it before it's warmed up... I'm not sure how to describe it. I just had it in for an oil change slash whatever number inspection a few weeks ago and I don't know if they didn't even look at the bike or what but it seems to be getting worse every time I ride. What could be the problem?
