HI, Just recently (last month or so) since I have had my stock (CAT) exhaust on my 03 rs the bike has started to make this rattling sound (sounds like its coming from top of the engine area).

What could this be?? I also get it when I accelerate hard sometimes, but its very noticable while slowing down (engine breaking)

Could it be a bearing on its way out or somthing??

Not too sure,

Cheers, Adam.

Just a quick one, on my RS50 the baffle inside the standard pipe came loose, and at certain RPM's you would hear it rattle, if its the top end or main bearings it would rattle all the time.

Can you hear it when acceling, does the noise get louder as the bike revvs faster?

Check all the engine mount bolts are tight.

Cheers guys,

@ Craig, I recon its the exhaust then, coz it gradualy started and I must say I have ragged the hell out of the poor stock pipe so I recon its breaking up :P lol

It doesnt really get louder, just mainly happens when breaking.

Hopefully the Jim Lomas will be here this week! and I will wack that on and see it the noise goes.

I will also check the engine bolts!

Cheers guys, Adam.
