CBR250RR Exhaust Question

Discussion in 'Technical and Troubleshooting Torque' started by jgul2, Jul 14, 2006.

  1. Hi All,

    I have noticed a small hole on the bottom of my muffler which looks like it has been manufactured into the muffler, not one that has developed from corrosion.

    Please see below:


    The picture is of the underside of the muffler. The hole is in the middle of the black area visible in the picture and is quite small.

    Does anyone else have this on their muffler, or is this something i should get sealed up?


    P.S. Its a '99 model Australian Delivery
  2. possibly a drainage hole?

    not too sure mate
  3. Yep, most likely a drainage hole.
    I had one on the FZR250 and it's blow soot and crap onto the swingarm. Just lived with it.
  4. hey MattyB, so u have one of these (drainage) holes as well?
  5. its a drainage hole ive got one on mine..no need to worry
