So I just bought an old 1985 rm250 and I am fixing it up to start riding. I took my seat off in order to put the rear shock on. I noticed that my silencer was connected to the pipe in what seems to me to be a janky way. It has some sort of tape wrapped around it with a wire around that. When mounted, the play isn't noticeab;e, but with the seat off it wiggles when I move it...is this normal. How are silencers normally attached to pipes? BTW the pipe and silencer are both "DG." Thanks for replies in advance.

sounds odd, shouldnt be any tape and it should be pretty tight without the seat, a picture would help if you have one

2 stroke pipes usually just have a rubber tube an inch or 2 long sealing the 2 together

Sounds like a home made joint. In a pinch I've used an old innertube and hose clamps.

I asked the previous owner about it and he said:

"that's an exhaust wrap. it's supposed to heat up and mold to one piece around the pipe. or you can go and get a rubber wrap from cycle gear or somewhere and clamp it on with hose clamps."

I looked around at other sites about it, and didn't really see it described for this particular purpose, but I don't think it is as whack as a solution as I thought. I will probably leave it the way it is for now and if there seems to be problems from it, I will go from there.

Thanks all!

Go to your dealer and get the rubber adapter piece the gives you a nice seal between the pipes. You can also add some high temp silicone seal to make the seal even better. That muffler tape wrap stuff will never give you a good enough seal and it looks like a POS.

Here's a link to show the rubber gasket.
