I just came home from another thrilling adventure in the Swedish woods on my brand new 520 EXC. :cool:

Not that I lack power but I am not quite satisfied with the sound of the bike. :think

Is there any one out there who has any experience of taking away the "grid" in the end cap of the silencer?
Does the bike become to loud or does it have any strange effect on performance? Do I need to adjust the jetting?

The grid at the end of the muffler can just be ground away using a small dremel tool. Your carburetor has a 24.5mm throttle stop on it that can also be removed. Your carb has a different jet needle from what is used in the USA. Your carb has the OBDVR needle in the 3rd position. In the USA we use the OBDTM in the 4th position and I would use this needle if you remove the throttle stop.

I think that it is located in the linkage on the right side of your carb. It is a small metal bracket that limits the slide from fully opening.

Thanks but what about my original question. Do anyone have any experience in taking the screen away and did it make the bike to loud?
