Do the performance exhaust pipes with jet kits really make a big
difference in your gas mileage? What about the way the KLR runs?
I'm finally considering one, gas is still at $4.41 per gallon here.

Does the price of fuel argue for or against a pipe?
Rejetting for a pipe will usually hurt your gas mileage. Adding the pipe does little if anything
for your performance, typically adding a couple of horsepower in the midrange at the
expense of a couple at the peak. Of course, YMMV, but if you want more performance out of
your bike, first spend the money on suspension. If you just want a louder bike, then...

The KLR is pretty economoical for a 650 carbureted single. Most mileage
gains will come from riding habits. Anything you do to enhance
performance will be accompanied with a decrease in MPG, especially if
you "enjoy" the added performance. I see the best mileage if I keep
speed to 40-60 MPH, keep the revs below 5000 and don't accelerate hard.
How boring, right? But you said MPG, and thats the best way to get
there. Mileage decreased when I ride 70MPH and run it up hard in the
twisties. You be the judge.
I added a low resistance muffler, and moved the richness screw out as
recommended, but thats it. I'm getting a consistend 60MPG, and am
pretty satisfied.

All,
I would like a louder bike, I have a habit of near misses with dear. My
brother on his XR650 has a white brothers exhaust and has alot less run
ins with deer, my theory is its his loud exhaust.
I like supertrapp, but its a bit expensive for my blood. I saw a forum
post on advrider using a muffler for a John Deere tractor that was
fairly attractive to me, but I have not got a definitive answer from
anyone about the sound of the tractor exhaust.

Rode with a SuperCrap/SupperTripe for while. My advise is don t buy one.
Have my doubts about your deer theory but who knows ?
Bogdan, who thinks in most things quiet is better. Doesn t even like to camp
near a loud stream, prefers the sound of wind through the trees.

Since pipes generally direct the sound to the
rear of the bike, the extra loudness is most
noticed as you're driving by and beyond.
Loud pipes serve to pi$$ people off more than they "save lives."

Richard,
While I'm a big fan of quieter bikes (mostly due to habits of riding
in areas that are accepted but not necessarily legal) if you really
want a louder exhaust, drill six 3/8" holes in the back of your stock
exhaust. I did this a long time ago on a bike now long missing when
we on the list originally went searching for the cure to tweety.
Makes it louder, and doesn't cost much. I don't know that it will do
anything for run ins with your "dear" though. Does she just like
Hondas better?

With all stock engine and 'rough-tuned' jet kit, I went from 60mpg down to
43.
I didn't notice a whole lot of difference except a mass of power coming on
at 5000rpm. I probably didn't have the jetkit setup just right either.

(haven't gotten a sniffer yet).
I want to replace my pipe because the bike makes a loud tweety noise which
almost drowns the VW bug of yore sound.

I could've sworn there was a video on Youtube showing that exhaust. I
haven't stopped by the tractor place to pick up the DR-8 pipe yet. I was
pondering gutting my pipe first.

You can get rid of Tweety without too much trouble or cost, even if you
have to buy a few tools to get the job done.
