Think I may have some rod knock. I was riding around today and didn't give it enough throttle for the gear I was in, but instead of it bogging down like normal I got a sound kind of like a large ball bearing rattling inside of a thick metal can. Almost like the ball in a can of paint, but with a deeper pitch. It lasted for four or five strikes then went away. Didn't get any indicators, or codes on the instrument display. Operated fine afterward too.
Now, I'm getting close to home, and stopping at a light when as I'm letting off the throttle to idle and I hear another noise. It is at the same speed as the regular exhaust noise, and sounds like when you blow out your mouth but keeping your lips closed, then let them flap open and closed. Like you're giving someone a raspberry. It happens for a half second, then is gone with the regular idle noise. The noise is more prevalent after the bike has been ridden for a while. It's not there at all when the bike is cold. I can also feel it while it's happening. I can't say that I've noticed it before. Hearing what I heard when I bogged it down may have made me more aware.
I took a video of it, but the sound sucks and I can't hear it in the audio. Does this sound like rod knock to you guys? Is there anything I can do to check this out short of tearing the motor apart?
Thanks for the help.
