Have you checked your sprocket lately? Here’s new compared to used. The aluminum (shown here) wears down pretty quick, I since switched back to OEM steel, since the weight doesn’t concern me and I prefer long wearing.
So, when you are cleaning your chain (yes you need to do that too) (and yes I am speaking to myself as well, lol) check the wear on your sprocket. You definitely do not want to let it go further than this, and if there are teeth missing, replace immediately.
While you are at it, don’t forget to check oil level and tire pressures. 🙂
