Sharp and loud engine sound

[jocser]

Hi,

As already told in a previous post that youve might have read, I had a spooge problem, which seems to be better.
Today a friend of mine rode my bike and I was standing there without a helmet and my god its really really loud. It sounds like someone is hitting cooking pots. Muffler packing is a little black but in good condition in my opinion.

The rubber sleeve that connects the pipe and muffler is New so that should be good.

I have 2 Air intakes on each side of the airbox, might these cause that sound

The pipe is an FMF. Bike a 2012 ec300.

Anyone has got some tips?

Grts!

Have a listen to the video from this thread. Sound the same?

Check the seal between the exhaust pipe and cylinder/spigot?

Mine was really loud and raspy when I got it. The exhaust packing looked okay on the outside but inside it was clogged, as were the holes on the pipe. I cleaned all the holes out (which was a messy and crap job!) and replaced the packing. Now its a totally different quieter sound.

Tiddles, what packing did you use? Mats of fiberglas? I dont really know the english word for it so I hope you understand what I mean

I've always just called it 2 stroke exhaust packing, you can find it on eBay, amazon ect.

I use this stuff

And it seems to do what they say in the advert. Cleaning out the holes on the perforated pipe will have helped a lot too though.

This is what came out of mine.

I did mine over the weekend.

Very similar. Hadn't soaked right through but clogged up the core. Haven't started it but imagine will be back to its old self.

I just cut up some ROXUL sound insulation and use that. I usually always have some laying around from a job. It works as well as the store bought stuff.
