I'm NOT very mechanical, so kinda worried (And please don't laugh at me TOO much)... My Valk has recently started whistling at idle. (Whistle while you DON'T work) If I give it a bit of throttle it stops rather abruptly at around 1200 RPM, but starts back up once the RPM go back down. The pitch climbs as the RPMs climb up until it goes silent. It ONLY happens once the engine is good and warmed up. From cold to a good 10 minutes of riding or so and it doesn't whistle at all, I have to ride it longer than that for this to start happening. Initially I was told doing a desmog would likely remedy it, so I did that (Which wasn't pretty for a non-wrench turner like me to accomplish, but I'm rather proud of the fact that I got it done.) No regrets on the desmog, glad I did it, the backfiring on deceleration had gotten pretty bad on my Valk, so that was a job that needed doing, but... The whistling is still there... It kind of sounds like a tea-kettle that's about ready. I've already talked to a few folks that think it's a vacuum line and needs to be replaced, not super critical though, but wanted some confirmation, I'm worried I'm mis-diagnosing it and it's a bearing going out or something that could leave me and my daughter on the side of the road somewhere on our way to Montana, so I took some video to let the experts hear, let me know what ya'll think: Thanks for any insight! https://www.youtube.com/watch?v=CVsrbtIrONA |

Vacuum line cracked was my first thought. Since you are desmogged, I would imagine you still have a vacuum line to the petcock. If that line is cracked you should experience fuel starvation symptoms soon.

I have no clue with this. But my first question is, is it speed related or RPM of the engine? So it's doing this while parked and just revving the engine.

How about the vacuum Caps on the back of the intake tubes? Did those get replaced on the demsmog?
Will also wait on reply to Chris's question whether stopped and idle or if this is moving whistle.

You don't say the mileage but it could be one of the cam belt tensioners. Those bearings run pretty dry and can be noisy.

Thanks for the feedback...
It's a '98, I'm the original owner, 117,000 miles, and it happens with the bike parked in neutral...
I replaced the timing belts at 83,000 miles, if that enters into the equation?

OK on the belts but the idler pullies are still old. |

Okay, update and planned course of action up for discussion:
Got a automotive stethoscope, rode to warm the engine up and start the sound, and probed around, couldn't pin down where it was coming from.
One other observation, the sound is VERY temperature dependent. Sitting at idle in my garage, when the radiator fan kicks on the sound stops shortly after, and re-starts a minute or so after the radiator fan stops.
Took the timing belt cover off and couldn't notice a discernible difference in the sound, but I don't have the best hearing, had my wife check, she thinks it might be coming from that area, but again couldn't tell a difference with the timing belt cover on or off.
Checked my records, and while I did indeed change the timing belts at 80k, that was in 2007, so guess those are due anyway, and if I'm doing that and they're a failure item I'll replace the tensioner pulleys as well.
Will also order a petcock vacuum hose and see if I can replace that while I'm in there. Probably do the spark plugs as well, seeing as I don't think I've done that in 12+ years.
And once I've done all that, if it's still whistling, I'll be offering adult beverages of choice in Billings to whoever can figure it out.

Just for confirmation, when we're talking about the tensioner pulleys, we're talking about these, right?  (Honda part# 14510-MG9-008 ) |

Since you did a desmog, you had the intake tubes off. Could you have displaced one of the intake tube o-rings when you put it back in?

I would pull the intake tubes one at a time and check for proper positioning of the o-rings. A displaced o-ring would be a big air leak.

Are those the udder looking things that come down off the airbox? If so, it's definitely possible, but the whistling was there before I did the dessmog, and still there after... Not an impossibility to have one that's leaking in the same way before and after being removed and put back on, but odds lower, right? |

The chrome intake tubes should have "tobacco stains" around their base if
they are leaking...

If the sound changes with the fan running, I would give a good listen to the alternator, take the cover off and listen there. Only other thing is could it be a vibration or buzzing noise.

You coming to Inzane? If so I'm about 99% sure I owe you a beverage. Update on the story (And I still regret nothing I've done, it all needed doing anyway) Today I replaced the timing belts, both idle tensioners, the petcock vacuum tube (And the spark plugs because hey why not). Went for a test ride to a friend's house, got there and it's whistling. Remembered your comment about the water pump, my friend has an automotive stethoscope, he prodded a bit, and when he hit the water pump he recoiled in pain. Almost positive that's the culprit. So now I'm off to order a new water pump. Researching what all is involved in changing that out. I'll google on it and read the manual too, but anything else I need other than just the pump? Any tips or tricks beyond what's in the manual for changing a water pump? Thanks again ya'll! |

I believe you and will do so but curious, why is this necessary? Edit - Ah, was told that removing the water pump WILL drain the oil for me, so best to do it in a controlled manner beforehand... Thanks again for the advice! |

Question due to my impatience, I'll be able to answer this tonight myself when my new water pump is delivered but, I went ahead and pulled the old water pump last night; should the impeller turn freely once removed from the bike? I AM able to turn it but it's very stiff and requires quite a bit of effort, seems like something like that should spin freely?

Just checked my new one (never installed) and its a tight turn. I mean it turns freely but its not like spinning a top. it takes a bit of effort to turn it |

Thanks for checking, that sounds about like the old one on mine is doing... Guess we'll see if that was the problem after I get my replacement in and get everything put back together...
Thanks again!

New pump came, got it put on, hoses re-connected, fluids refilled (Made the there was an o-ring on the shaft of the new pump), bled the coolant, let 'er run a bit to warm up, and it started rhythmically squirting coolant out in the space between the pump and the engine... I'm off to google up what I can learn, but in the meantime... Anything obvious or simple before I drain all the fluids out, take the pump off, and fiddle with it some more?  |

You like bourbon? I'm planning on bringing some of my home blend/aged bourbon, and it appears I owe ya' a wee dram! Woot! Put a new hose clamp on the top, tightened it down, started the engine, no leaks (*KNOCKING FURIOUSLY ON WOOD*). Took her for a ride, beat her hard got her hot enough for the fan to come on a few times, and no whistling! Looks like water pump was the correct answer! Sadly, your competition is down to One Dan. Dirty Dan has had to give up riding.
Yeah, sadly had seen that, but the amount of dirt on his Valk was legendary, thus I still hold his status in high esteem and a pinnacle I can only hope to some day match... |

The pics I've seen of your bike you wouldn't stand a chance against him.  So, it must have been a bearing in the water pump going out ?
