Exhaust fumes while towing trailer

[ldbeemer]

I recently started to tow a Uni-Go trailer with my 95 K75RT and noticed a heavy amount exhaust fumes while at mid speeds, 40-60MPH. Has anyone else experienced this, and what can be done to rectify it, other than not towing the trailer? I don't want to pass out on a long days ride from carbon monoxide poisoning.  :falldown:

You can smell the exhaust fumes?

Or can you see them?

I smell them, the bike runs clean.

My naked K75 was an RT before I converted it.

One of the reasons I disliked the fairing was that it created a chamber of exhaust fumes around my head.

I had my RT windscreen cut down by about 8" and that helped.

It should be pretty obvious that the trailer is disrupting the airflow out from the back of the bike.

A 'comedy' suggestion could be to get a turn out tailpipe trim thingy that you can push into the end of the exhaust when the trailer is hitched....

Something like:



It might help a little if you could post a pic of the bike with trailer?

Here ya go, http://www.millproprecisionmachining.com/product/BMWK75EXT-200  Exhaust issue has come up before on the RT.  This guy came up with this neat extension.  $80

Never seen that before!  Makes me wonder what else is out there for the K75!

When I get dug out of the recent snow fall here I'll see what the local auto parts store has. If I can work with their stuff i will, if not I'll order the one Chaos referenced which is a little pricey but looks well engineered. Looking at the pre-made one I now have a good reference of length and turn down. Air flow is a tricky thing to master.
Thanks for help

another option could be a staintune or Mac pipe that's longer than stock, but those are scarcer than hen's teeth and may be noisier than you like.  I found a Mac cheap on Ebay a couple years ago, happy as a clam with it!
