Hey i have a problem. What is this noise?

 

Its worth checking the crank pulley, luckily that's what mine was.

 

Before you spend a bunch of cash, check out the bushings on the belt tensioner damper (black hydraulic rod). The bushings dry out over time, fall out and cause the damper to rattle against the bolts. It's a cheap easy fix. You can get to it easily by removing the right front wheel and fender liner.

 

Check your chain tensioner
