RATTLE ON MY NSR 125.................

Hi all,

I've got a rattle on my nsr 125, ONLY at idle.

It is a little bit noisier when she is warm, and is not audible above 3000rpm.

I know the bike has been looked after before I bought it and it is always warmed up before being ridden.

And is never ridden above 10,000 rpm. Always used top quality synthetic oil.

I've had NO drop off in power since I bought it in October, so I'm a little bit confused as to what it can be.

Help
Myke.

Loose bolt somewhere? Check all of your exhaust bolts especially at the head, then check all the fairing bolts.

Where is the rattling loudest?

run her on tick over, and gt someone with a fine ear to have a listen, it could be rattling above that RPM, but cos of the engine you don't hear it.

Something obvious that's worth checking is the tank support arm. My NSR made a horrendous "clunking" sound while idling, with almost exactly the same symptoms as you describe.

Turned out the arm hadn't been placed in the retaining clip properly by the previous owner. I hooked it in, and the noise vanished Smile

Best of luck!
