For the past week or so I have been noticing a faint ringing sound when I am in first gear in low rpm's(3,000-6,000) then it either stops making the noise or the bike just gets too loud for it to be audible I'm not sure. It sounds almost like a piece of metal scraping on the ground but it is not loud at all. It's sort of like the sound the brake pad of a car makes when they wear down to the little metal sensor, but I don't think its my brakes because they seem to be functioning fine. Has anyone else experienced this? I have no idea what it could be and cannot seem to pinpoint where the noise is coming from. Should I be worried? I thought I would try to find the problem myself before I let a mechanic take all my money for a small issue.

Just a little more information would help please, what year is your bike? Km's? when was your last oil change? Is there oil? I know Hondas are notorious for CCT issues which start rattling not grinding at 3-8 thousand RPM. Sorry if I am being very vague but it could be a number of issues.

Hmmm... when was the last time you cleaned and lubed your chain?

Every chance that that is what you are hearing...

My bike is a 2009 with about 5200 miles on it. Yes it has oil in it! And oil was just changed maybe 1300 miles ago. I know it is not the chain because I just installed a new chain and sprocket and have only put about 100 miles on it, however the ringing was occuring prior to the chain installation and has continued after it also so I don't think it has anything to do with chain and sprocket. The only way I know how to describe it is like I said above, the way a cars brake pad sounds when it has worn down to the little metal sensor that scrapes against the rotor. Do motorcycle brake pads have this feature on them also? I have not changed brake pads since I bought the bike. Also I have never really messed with th cct so don't know what to look for there.

Ok then... not your chain :)

The sound the pad makes on the discs is a scraping sound... can't hurt to have a look at how worn they are though. When you look at them you will see a little cut made through the middle of the pad material. Once they have worn down to the level of that cut they need replacing, that should leave about 1 - 2mm of pad material left before your running on the backing plate.

brakes appear to be fine. How do I check the CCT? What am I looking for and what do I do to fix it if this is the problem? Also am I damaging the bike by continuing to ride it?

The CCT will make a loud distinct rattle... you may be worrying about nothing.

Take the bike down to a shop and see what they think.
