I am new here, I have a 06 Vulcan 900 with 2600 miles on it. I know yall are tired of the my engine makes noise stuff, and yes I done did a search on the noisey 900.
I hear some of the noises that some of yall have heard, but there is a noise that sounds like a rod knock when I am above 50-55 mph, like a rod knock it tones down when I get off the throtle, it kinda has a rubber sound to it and not so much like the classic metalic sound of a true rod knock. The bike runs very well and this noise is not heard at lower speeds, even when I am relly going through the gears.
Any others hearing the same sort of noise on your 900??

Dude, gut your pipes and forget about it. When you're rod is knocking you'll know it when it sticks out the side of the engine WITH the gutted pipes.

I put my non gutted pipes on last week and I hear everything. The reeds, the gears heck, the dang fuel pump, whole things sounds like a massive sewing machine. When you gut the pipes or put an aftermarket set on, all that goes away, 'cept for the smile.

MM,

I just had my bike in for an oil change and I was telling the machanic about that same noise. I have about 9600 miles on the bike and just started to hear it about a month or so ago. He rode it and said it was nothing to worry about. I also had him check my stator as some are having problems there too, but mine checked out fine electrically.

I guess it's just part of the character of the machine.

My 900 as always had some noises, but nothing that ever really bothered me. After reading all the stuff on here about strange noise I guess I am hypersensitive about it. I was about 20 miles into a 400 mile ride the other day just having a good time. The traffic was light and I noticed I was gaining on a bike - a big bagger. I was riding along behind him back about 100 feet, and there was enough traffic in the other lane that I couldn't pass. I started to notice a funny sound comming from the front of my engine. At first it sounded like a fan that is hitting something while running, but not very loud. I was coming up behind the other bike and the sound was getting louder. As I got close enough to pass and started around, the noise was much louder and starting to sound like someone moving a length of chain around in a tin can. I was starting to get mad, remembering all the stuff I had been reading about noises and as it was getting worse I thought that I would not be making my trip. I was almost to an intersection where one road was the direction I wanted to go, but the other direction would take me to the dealer so I was getting prepared to head for the dealer as I passed the other bike. As soon as I was on the other side of the bagger, the noise was gone! The only thing I can think, is that the awful sound his bike was making was reflecting off the front of my bike and the windshield directed the sound toward me. It sounded exactly like it was my engine. Very strange, but I'm just glad it wasn't my bike. So back to your question - no I don't have that sound - yet. ;)
