Question coasting noise

After I adjusted the chain on my kawasawki ex500 (2001), i noticed that when i am coasting, there is a certain whining noise that comes. it was always there, but now its louder. i thought it might be that the chain was too tight, so i loosened it a bit. it's still loud. what can i do about this?


p.s. i searched google, and some people say it could be the timing belt. when i get home, i am going to take a look at it.

They don't have a timing belt, but it could be gear whine from your engine. I guess it depends on how loud the noise is. Hard to tell without seeing/ hearing it.

Make sure your chain is properly adjusted and that it is properly aligned too. Make sure the chain is properly lubed as well. After that, make sure that there is nothing hanging loose or broken from the bike somewhere. Make sure you have plenty of engine oil as well.

Motorcycles make a "whine" anyway with gears/ systems that the engine runs with, it could simply be that and probably is.

If the whine is really loud, and it concerns you or if your performance is affected, take it in to a shop like Motorcycles Unlimited to be diagnosed.

So you replaced the chain and now the noise that was always there is louder.
Why would you suspect anything other than the new chain?

If you replaced the chain with a different brand maybe it is louder than the other brand.

I assume it is an O-Ring chain.

Did you replace the sprockets too?
If not maybe the old sprockets are a bit worn to match the old chains slightly streched spacing and now the new china makes more noise on the somewhat worn sprockets, (Especially the rear one)

i didn't replace the chain, just adjusted it because it was getting loose. someone told me that it might be the back brakes kissing the rotor, but idk.

Well if its making noise while coasting(and not changing with RPMs) then that rules out the engine. The things I would check are the chain, the wheel bearings and the brakes. How many miles? The brakes will "drag" if the bolts on the caliper get stuck. Most rear calipers are made to move side to side a little bit. Or the pistons in the calipers can get stuck.

um, not to sound like an idiot, but the noise stopped. i suspect that the brake pads were too close, and finally moved back a bit.

The brakes being "too close" is whenever the pistons (in the calipers) get stuck. Whenever the bolts for the caliper get stuck the pad will wear uneven and can also sometimes drag

Lol, with a 500, you have to get used to all sorts of funky noises otherwise you'll be in and out of the shop constantly and always worrying about what catastrophe could result from this or that new noise. My ex500 made a cacophony of weird noises somedays and the next day they would be gone and all that you would hear is the usual lawnmowerish motor going at it. Glad the sound went away, dude, I can relate to your confusion and frustration!

If you need any more help, let me know. I work off Orem and 288. I could pop over during lunch and look at it if that helps.
