Chirping sound

OK, spring is long gone but about 3 weeks ago I started hearing a kind of chirping sound from the left front of my 1300 S. I had just recently added some WalMart driving lights so I just assumed they were the source. Cleaning up the bike this past Saturday the vacuum hose on the pet cock came lose and I just put it back onto the nipple. Well this afternoon I finally got a chance to take a close look at the lights, I removed them and went for a short ride and the noise was still there. So I started looking for anything loose, checked all the covers, plug wires, etc. etc. and could not see anything wrong. I was about to start just trying to tighted every screw and bolt when I ran my hand along the back side of the aformentioned vacuum hose. There were 3 short very small cracks in the hose along the back side where you could not see them. I was able to pull the hose and trim about 1/4" off and slip it back into place. Another short ride and the noise is history, also the slight rough idle that I just figured was due to temps dropping had smoothed right out. I guess the moral is to keep a very close check on those vacuum lines, I haven't had the tank off or done anything in that area at all in several months so I guess this falls under normal wear.

Keep it in mind,

My vent hose on the tank cracked and I had to trim an inch or so to get to good rubber. Sounds similar.

Obviously your pipes are not loud enough

Good catch though.

How old were your bikes when this happened?
As regular maint. I'll replace mine every 5 years.

Hmm, now I gotta go tell my wife that you're supposed to replace your bike every 5 years, She thinks as long as it still runs I can just paint it again and keep riding.

George

Sounds right to me.

I thought changing the paint qualified as a new bike But really the bike is only 18 months old with something over 11k miles. Maybe its the humidity here in Carolina.
