Yamaha SR125 front wheel noise.

[usmaan_88]

Hi,

I recently purchased a 2000 yamaha sr125 in pretty good condition. It runs great but after i adjusted the chain slack the FRONT wheel started to make noise when rotated. It could just be moisture because it rained the night before but i'm a newbie and have only owned a bike for 2 weeks so i want to be careful.

I know this is a stupid question bu any help would be appreciated.

Cheers

Could be a few things.
Wheel rubbing on something.
Wheel bearings on the way out (more a sort of "grumbling" noise when turned).
Brakes binding slightly due to light rust on the drum/disc (would stop after a few hundred yards).
Brakes binding slighty due to being overtight (noise wouldn't stop, handling would be horrible, brake calliper/drum hot without having used brake (carefull, sometimes REALLY hot).
Speedo drive in need of lubrication.

Hehe, I've had this one...

It's the shain making the noise, not the front wheel. It just sounds like that's where the noise is coming from.

Don't know why it does, but it just does. I had this on my 125, and when i changed the chain, the noise dissappeared. Very odd indeed. The fact you say you've just adjusted the chain is a give away too.

well , it could be now u have a bigger / smaller chain it could be banging against the chain guard it could be a number of things your best bet is when you are riding it have a good listern where it is comeing from .

The SR chain shouldn't be too tight, I did that once and it whined all the way to work and back again. the adjustment is easy though. just adjust another notch up and use the little viewing window for the chain on the chainguard... this window gives the right tightness range for the chain as well.

Thanks a lot guys, I haven't had time to look at her yet, I'll check it out tonight and see what works!

I had a look at it, for some reason it doesnt make the noise when i put it on the center stand and spin the back wheel. And the noise comes when the engine is off too. The front brakes are working fine and the handling is still the same. I'm going to isolate the front wheel to and see what happens

And about the chain adjusting plates, the manual says to move them equally to set the tension accordingly, but what i dont get is the little notch they're supposed to latch on to, when tightened and then moved back to loosen the chain the plates just fall freely because they no longer catch on the notch. Am I doing something wrong?

What sort of noise? Some noise is normal - you shouldn't really hear it while riding, but if you put the bike on the stand and spin the front wheel it's quite normal to hear a sort of 'dragging' noise.

As long as the wheel spins properly it's not a problem. It's probably just the brake pads rubbing against the disc (which, due to the design of disc brakes, they do all the time - believe it or not).

Like I say though, you definitely shouldn't hear it while riding.
