VT500E whining noise

Hi.
Some time ago I bought this 1988 VT500 E with supposedly 58 k on the counter. It's a well handling bike, although not the prettiest design.

Recently, it started making a whining noise when warm and only at idling engine speed. The sound will disappear as soon as the revs goes up and return at idling speed. If the engine has been turned off for a few minutes, the sound is gone, but will return after a few minutes driving. At first, the sound seem to come from the right side of the engine (clutch-bearing?), but I do now suspect the water pump may cause the noise. Does anyone recognise this problem?Thanks.

The water pump is on the lower left side. Get a cheap stethoscope from Harbor Freight to pin point the sound. Or even a few feet of hose held up to your ear.

Thanks for sharing this with me, Mother.
I have been thinking of just trying to forget about the noise, but it's a rather annoying sound, so I'll try to solve the problem.

The noise from your bike is a wee bit more pleasant than my noise. I'll see if I can upload some sound.

I'll let you know, if I succeed ti fix the problem.

Thanks for your advice, Swifty.
My daughter in law is a doctor, so she probably has such a tool in her doctor's bag. I'm sure her patients won't mind an oily spot on their chest

Just wrap the end in a plastic baggy and no one will know the difference.

If you take a look at a bike known as the Yamaha Vision...you'll see certain similarities...can't remember which one came first, but the Vision was a 550. Anyway, they had a slightly better looking & much larger windshield, so if you are a semi-decent welder and found one, you could upgrade your shield by welding on the bracket. Everything built in the 80's could be switched around if you had some welding skills

Meanwhile, deep cleaning of an engine is sometimes a neccessary evil. Running Multiple radiator flushes on a Saturday pretty much kills a Saturday, but your bike will thank you for it! Ain't a bad idea to do it for ALL your vehicles at the same time...at least 3 radiator flush bottles per vehicle, lots of distilled water, and rad fluid to refill when it's all done.


Also...after that's done, oil flush/change are the next Saturday's chore. Also realize that synthetic oils can make a bike sound quite different...so don't be afraid to experiment between Standard and Synthetics.

Ride paranoid. Don't let anything distract you.
Keep the paint side up, wear the lid & leathers.

Thanks Big Shrek.

I must try this radiator flush, but meanwhile the noise has disappeared. My bike probably saw me with the stethoscope around my neck

About fairing, I must confess I did actually have a 550 Vision a few years ago. But I did not like it's fairing (nor the bike's handling). Maybe I'll do something else and make a café racer out of the Honda next winter.

But thank you for your ideas.

I enjoy the Chris Fix videos and if you have decided to do a rad "flush" at least this one shows how, however this procedure is not required and NOT recommended by Honda (or Nissan, GM, Ford etc.). The dark color of "old" coolant is meaningless. The coolant and the flush are environmentally hazardous so flushing creates additional environmental issues. Honda specifically warns against using any aftermarket "flushes".

As with most automotive consumables, coolants and cooling systems have vastly improved over the years so that typical coolant change is once every 5 years (for instance the 2001 Honda Accord recommended first coolant change is 120,000 miles).

Well, to be honest, I have tinkered with quite a lot of old cars and bikes for the past 50 years, but I have never flushed a cooling system. Admittedly, I have done other nasty things to the cooling system in order to try to repair a radiator or a cracked cylinder head like putting an egg or other magical stuff into the cooling system ;-(.

However, the idea of flushing the internals of the human body seems to be very popular in these days, so maybe this goes for our beloved bikes as well
Thanks for your input B
