Blowing Exhaust

[edgas250]

My exhaust is blowing in between the rear silencer and center section, the rubber O rings are no where to be seen, and also how should the round peice which sleaves over the center section be placed, should it be loose inside the silencer? or protrude out?

Thanks

Matt,

The o-rings are necessary to keep vibration from wearing the metal parts, as well as sealing. If you are in a bind and don't have any o-rings that for the inside of the final muffler, wrap multiple layers of plumber's thread sealing tape around the mid-muffler spigot (to get a tight fit) and then smear on a little hi-temp Silicone sealer, install the final muffler and let set overnight. The thread sealing tape is Teflon and will allow a little movement between the mufflers and help seal the joint.

"how should the round peice which sleaves over the center section be placed, should it be loose inside the silencer? or protrude out?" not quite sure what you mean by this, but there should usually be a slight gap between the mid and final mufflers and each one fits a little different.

if you have the silencer off, look at the end where it goes to center box, in the hole is live a sleave which is loose on mine it sits inside the silencer, is this right or should it stick out and seal around the center box

The only "sleeve" I can picture inside a final muffler is the perforated core of the pipe that is inside the muffler proper. If that is loose, you'll want to take off the end cap and re-pack the muffler before installing it. If the perforated tube is loose inside, the harmonics inside, when the engine is running, will bounce that steel tube around enough to wear through the aluminum tubes/sleeves it fits in and the tube will not be properly aligned, causing power loss.

Hi EDGAS,

When you look into the end of the silencer, where it fits onto the centre box, there should be an aluminium sleeve/tube with one or two grooves machined for fitting the O rings. If your bike has this piece loose, it needs welding back into place. This aluminium piece which holds the O rings, fits over the spigot on the centre box. Inside the silencer, there is a steel perforated tube that Jon explained about, this is removeable and has fibre packing wrapped around it. This perforated tube pushes into the aluminium sleeve/tube at the entry point of the silencer.

Bye, PeterB.
