Screech/whine at low RPM?

Postby Revrant » Fri May 01, 2015 7:56 pm







I just took this video earlier, the sound started yesterday but seemed to go away, now it's back and I'm amiss as to what it could be, I thought it was the alternator but it doesn't seem to be coming from that area.

Thoughts?

Could be a timing belt pulley bearing?

Get down a bit closer to the timing belt area to determine where it is coming from - maybe an electric fan?

when it started were you riding it or was it just started up ?

Uh wow I really hope not because I cannot fix that, and I don't have the hundreds and hundreds of dollars to take it to a shop located an hour away, the only place that will see it.

I'll have to listen during the day and see if I can figure out the location, and I don't know exactly when and how the noise started.

I discovered my coolant levels had vanished, I refilled it and prior to that smoke or steam is now coming from the right side beneath the handlebars, somewhere I can't see.

This is turning into something awful.

Sounds more like a whistle than a screech on my computer. If it is, I'd be looking for a vacuum leak. Hope that it is that simple.

Could be a water pump. It sounds like a bearing. If it was a vacuum leak the engine would most likely not run well. It sounds like it is idling OK.

Steam out the right side ? Is the radiator cap on? Left side would probably be from the overflow tank. I think the vent hose goes down the right side too.Which side did you put the water in? Possibly just filled the overflow and not the radiators? Didn't you see any sign of a leak before finding it low? If you have steam, there is surely a leak somewhere. Does it make this noise when it idles, or just over 1000 RPM? Got lots of questions, hope we can give you some answers. :)

The noise may be gone now, but the engine is running very hot and I still have this smoke or steam, the noise only happened when rolling off the throttle above 1000 rpm. Oh no, I must have been misled, I was told I could fill it by using the cap you use to check the level, I guess the previous owner was mistaken, it could be anything, it could even be antifreeze leaking, but it was only 80 today and the temp was edging past the limit toward red.

How do you fill it with coolant if not that way? Do you have to physically remove the tanks?

On the right side there is a radiator fill cap. That is where you fill the radiator. The overflow bottle is on the left side and you should keep the level as indicated in your owners manual. If you don't have an owners manual or a service manual, you may be able to download one here.

No you don't have to remove the tank. Right side of the key where the fork tubes go down. Remove the right side and you should be able to see tha radiator cap. ONLY WHEN COLD! Fill there and start it and watch for bub bles keep filling but not to the point of hot. Replace the cap, then look at the reserve tank.

Rolling off the throttle increases the vacuum. Sure sounds like a whistle to me.

These are the best illustrations I could find showing the location of the radiator cap. Since you apparently know where the reserve tank is located, on the left side of the bike, the radiator is in the same location on the right side of the bike. Remove that plastic filler piece to the right of the ignition switch area. If the radiator is empty, filling the reserve will not fill the radiator. Remove the radiator cap, very similar to an automobile, and make sure it is filled with antifreeze. You do not want to run that pump dry. As was stated earlier, you fill, run, look for level change, and fill, until you are sure it is free of air as well as possible. I've done that with the cap off and the bike to operating temperature. Then make sure the reserve tank is also at level. Test drive it at temperature with the cap on, then recheck the radiator after it cools, and recheck the reserve tank. At least you'll know where you stand for a starting point to your problem.

Oh, great I'll do that in a minute then, thanks, also this is the smoke/noise part, I'm wondering if this is the radiator or a tube seal.

This video looks like steam. Did you over fill the reservoir when you were filling? If so, it spills down and when it gets hot the steam comes out there. Does it smell like your antifreeze?

+1 it looks like steam to me also.

I don't know if it smells like the antifreeze, it doesn't smell like gas or oil though, so it must be, also it's overheating fast on the temperature side of things, or possibly the hot coolant is messing that up somehow, I'm not sure.

What am I doing if I overfilled it though? And how do I do that?

The coolant is not being delivered to where it is needed. Either there is not any, or there is plenty, but it is not being circulated.

There are a couple of water hoses that come in beneath the carbs that I have seen leaking and cause a similar issue on a hot engine. Might be worth while checking them. If antifreeze is leaking enough to lower the radiator level, you need to start pulling things apart to locate the leak. Its possible there are more than one problem here.

Yeah I can't fix this, I'm going to have to refinance the loan and have it shipped somewhere that can fix it.

You can too. Look at some of the how to articals and you will see instructioms on how to get those panels off. get a look at where the water is leaking from. We are here to help you! :) It is not that hard. :) At least we can find the leak.

I agree..... This isn't rocket science.... If you don't have one, you can possibly download a service manual from this site. I seem to recall there was one available for an 89 model which is nearly identical to your bike.

No manuals here anymore. All links are to bs Helm who wants $40-65.

But $65 now to have the manual, will save you $1000s later if you have to send it to a shop to fix what is usually easy to fix yourself. Spend a little, save a lot. ;) Would be a shame to spend 100s to send it to someone to tighten a clamp that you could have done yourself. :(

I agree 100%. My point was the ridiculous price Helm wants for repro shop manuals. Hmm, maybe I should go get some printer ink and get in the manual printing business... ;)
