I started my bike yesterday for the first time since winter hiberation. After the engine came up to temp I raised the RPM to about 2500 in neutral and held it steady. What I am experiencing is a noise and vibration in the grips similar to what a dry blower motor or alternator bearing sounds like on an auto. The noise is the same with the cluctch applied or not.

I plan to take my stethoscope home and pin point it, but was wondering if anyone else has experienced this. ..... Thanks.... Rob

Rob,
You're likely hearing the PAIR system operating, kinda like a low rumbling sound? It doesn't react the same in neutral as when actually riding. Go riding, and I'd bet you don't notice it.

it could be that over the winter a rat or a weasel took homestead in the machine somewhere and when you started her up a moving part has ground the critter to a oozing mess. Nothing a jug of Clorox and a toothbrush can't clean up. :rat:

Thanks Guys, It could, maybe be described as a low rumbling I suppose I'll check to make sure with a s-scope eventually. The first thing that popped into my head was a dry bearing (not an engine bearing). ..... How's it going Stu? .....If I can ever wade through the freaking cinders here on the street I plan to take a ride soon

PAIR is the acronym for the Pulse Secondary Air Injection system. Pumps fresh air into the exhaust for emission control. :shock:
Includes a solinoid and check valves and other stuff that will probably break at the most inopportune time. :?

I think that I would go with Stu's opinion first. He is well versed on the wing and his knowledge of the Wing is Legend.

Usually if we go looking for a problem, we will continue the hunt till either we find a problem or invent one.
