Hoping for some advice. My esr750-ex has recently been making a strange noise from its motor. While riding, it makes a noise on what I assume is on each revolution. It's almost like it's cogging, but other than the noise, I can't feel it struggling. Speed and acceleration seem normal.
There is no noise when it's just rolling, so it's definitely engine related.
Just wondering if there is something I can check to help avoid a dead motor at some stage...
