Original Exhaust

Hi Stefan,

Well, by the looks of your bike, at least as much as I can see, it's an 04 with the stock exhaust. It appears to me that it has not been modified. So here are a few suggestions.

If the bike is popping on deceleration, this can indicate a lean condtion, a simple solution would be to make sure the fuel adjusting screw is set properly, along with the correct pilot jet. Does this bike still have the stock jetting? And by the way, what bike do you have exactly?? Having the needle set too lean will also contribute to this problem, but, let's take one step at a time here. So, back to your muffler question.

Pull the muffler apart and make sure the packing is in good shape, as well as the "O" riing seals on both end caps.

With the muffler springs still attached, and the rear fender off, pull the the two mounting bolts off and make sure the muffler is seated all the way onto the collector. If your bike is an 04, it will have a ball and socket style of joint,(older KTM) where the muffler meets the collector. On my bike the mounting bracket for the muffler was off by 10mm, which did not allow the muffler socket to seat on the ball end of the collector, which resulted in an exhaust leak. I simply elongated the holes enough to make sure that the two seated together properly.

Finally, it might be a good idea to make sure that all of the exhuast joints including where the headers meet the cylinder, where the headers go into the collector, and the ball and socket joint have been sealed properly. Just pull everything apart and clean it thoroughly, and use a high quality silicone sealer such as Three Bond #1211. This stuff is expensive, but, well worth it. Be sure and apply the sealer liberally only to the male ends of the exhaust pieces so you get a good seal but don't end up with a ridge of sealer inside the exhaust. Wipe off the excess and let it dry for at least 24 hours, in at least 20 degress C.

Hope this helps,

if the tail outlet is 35mm diameter it is from a MX machine. the FE road and trail pipe is 25mm diameter.

i would consider having it repacked as dale suggests. otherwise i think the pipe is reasonable! you must be using it on the road...

the rivets can fall out and sometimes they are very loose also. so husaberg owners grind the rivetts off and begin again.

you must grind away all the rivets and check inside for all the wadding. renew this and then rivet it back up.

Not to Hi-Jack your thread but....

I see your from Dortmund. My favorite beer ever is Ritter Brau Dark from Dortmund. I can't find that beer over here any more, Sure wish I could get my hands (or lips) on some. Good luck with your bike.

continuing the hijack......

there are a couple drinkable brews from up north (dortmund and such), but virtually all the really fine and flavorful brews are bavarian.
