Help Please!

OK guys, This should not be such a hard thing to do......or is it??

Stock pipe 04' yz250f I want to repack it.

I have drilled the rivets. But it seems like they are still keeping the end cap from coming off. Do I just drill down the center of them, or is there more to it????

Is there a special way to pull the cap off besides using the "grab and pull" method???

Any help much appreciated!

I don't think the stock silencers are ment to be repacked or should I say they are not made to be repacked. I am not 100% sure about this

Don't listen to these guys. The stock silencer is made to be repacked. Take a 1/4 inch drill bit and drill each rivet at the front end of the can (near the midpipe). The heads should come off on the rivets, if not then take a small chisel and tap them off. Once the heads are off the pipe should come apart, though it may come apart hard. Hold part of it in a vise and pull on the other part and it should pull apart.

one more thing every once in a will the rivits stick use a small punch to knock them down into the muffler. and you can repack that muffler as much as you like.

Well, repacking a stock silencer is not that bad after all. I drilled the rivets, removed old packing, installed new packing, put new rivets all the way around,? Exhaust as a much deeper tone. Great learning experience.

Thanx to everyone for your help:ride:
