Idling noise

Haven't had enough time to service my bike but this weekend is when it will be done. I've noticed that the bike is making an idling noise. The noise is a slight rev that goes up and down. The bike definitely needs an oil change and I might as well change the spark plugs. Any advice would help.

Hey BF,

Can you put in your model and year, in your signature, so we can better help?

But, I am more interested in that hot rod, in the background!

Is that 1954 Chevy Coupe?

OK, cool. So it is not making noise because of the cam chain tensioner. I think they were fixed by the 2008 model.

Onto the next thought...

Are you saying the idle speed is hunting a bit? If so, many have noticed it, most of us have learned to ignore it.
Is your idle speed adjusted to 1100 rpm?

However, since it's older, I'd remove my MAP sensor and check the vacuum line and vacuum nipple are clean of any waxy build-up.

Skippy, my apologies for not responding back to you in regards to the chevy. That vehicle belongs to the dealer I purchased this bike from.

RaYzerman, the bike is a 2008 with 5300 miles on it and I find this to be very strange. The title say it was owned by one person and sold to the dealer with 5100 miles, he (the dealer) then rides it to 5300k. It definitely needs an oil change I and might as well change the spark plugs. The bike starts up with no problem but you can hear the engine making a low rev that goes up and down. I think it has old gas in the system due to it sitting for so long but that's a guess. Also, I think a long ride will clear all this up...what do you think?

Yep, fresh fuel with a dose of Seafoam for a coupla tanks. Long ride would be beneficial... see how it goes and let us know. At those low miles I doubt MAP sensor hose is clogged.

. I knew what to do but wanted to hear from a forum member that probably dealt with with something like this before
