Tail Pipe missing

Postby SAILOR » Fri Jan 28, 2011 11:27 am



I just bought an 1984 Aspencade and I'm now starting to realize there is a number of things wrong, or missing. Oh well. It appears that the last part of the tailpipe is missing. That would be the straight 2 inch pipe that is attached to the muffler. My question is this. Is there any concerns related to not having the exhaust be vented all the way to the back of the bike?

I am not aware of any safety issues due that bit of the pipe missing.. It will make the bike sound a little different (probably not louder but different) and you might get some soot or carbon deposit on your paniers from the exhaust gases but it should not be of any concern

You might not want to spend a lot of time idling, as the ABS plastic the panniers is made of will soften with not a lot of heat - if the exhausts are putting out hot gases that are rising into the bottoms of the panniers, it could end up melting them.

I assumed the panniers on the older wings where made from Glass fiber!! If as WingAdmin says they are plastic, you might want to do something to protect them from the heat of the exhaust gasses..

Nope, every piece of bodywork on every Goldwing from the GL1000 on upwards is made from ABS. You have to hand it to Honda for going forward with using a relatively untested and unique material (at least in this application) all those years ago when others were using much heavier fiberglass.

If it were mine, I'd mount a piece of flat steel to the frame, so that it is underneath (but not touching) the pannier, and paint the steel with a high-temperature paint. That way the hot exhaust will heat the steel instead of the plastic, and there will be an air space between the steel and the bag to allow for thermal insulation and also for the flow of cooling air. Some of the heat will also be dissipated into the frame through conduction.

That is kind of what I was thinking. First I'm going to assess how hot those panniers get with the bike just sitting there.

Any auot parts store carries chrom tips. I have seen some as long as 12 inches. Even if you have to put a small pipe inbetween, it's a hole lot cheaper than going back to Honda!

so how do you attach those crome tips when there is no pipe for them to slip over?

They are cut or broke flush with the muffler ends?

It appears that the pipe has been broken off the end fo the muffler.

Any chance of a picture of the offending exhausts? It does sound like the end has been cut/broken off which will make attaching anything to it a bit difficult. If we can see a photo, we might be able to make other suggestions.
