If I was making more money selling a particular exhaust system, I'm sure that I could justify it with charts/pulses/stats; who wouldn't? All I know is that I am fully satisfied with my mediocre, relatively quiet, non packable, stock-appearing though obviously inferior to the aftermarket,GSXR pipe.

Looks amazing! So what headlight are you running on it? It almost looks like you took the light off a KLX250.

No toll roads, some highway but no long distances.

The DR650SE sits well, going to go ride one this week.

Is there a year to stay away from?
Anything to look for?

Would the dreaded ugly KLR650, "gasp" be a better jeep, ugly ugly bike...?

Appreciate it.
The KLR will be much more like the 1150GS. If all you're doing is commuting with some light dirt and gravel roads, I would recommend the KLR over the DR. The KLR is going to be a much better commuting/highway machine as the wind protection is noticeably better. If you're just doing dirt roads and fire roads, the DR doesn't exactly walk away from the KLR. The guy I used to ride with was on a KLR for a couple years before upgrading to a Tiger 800, and I was never really able to get away from him when I was on the DR. When the trails got tighter and more technical, I had the advantage, but I would gladly have traded bikes as soon as we got back on the pavement.

Muffler flow

I just want to add some to the muffler debate.

I think you guys are missing a point: an engine is nothing more than an air pump. The more air you can get in it the more fuel you can add the more HP you get. Simple right?

While everyone is correct that a 650cc pulse of exhaust is harder to quiet then a 250cc pulse- you are missing the most important part of engine dynamics= airflow.

Doing the rough math:

A DR650 with a CFM efficiency of .7 (basic figure for carb 4 cycle engine) flows 56.1 CFM
A GSXR1000 with efficiency of .9 (basic fuel injection 4 cycle engine) flows 190 CFM!

That is about 3.5 times as much air goes through the GSXR as the DR (at max RPM). Even with two mufflers the GSXR mufflers were DESIGNED to flow more air per muffler then the DR engine flows.

How much air per pulse really has nothing to do with HP numbers; only dB.

Also, on a side note. When designing or selecting an air filter they recommend a filter that flows 2 times the air the engine requires.

Did I mention smooth as silk, for a large displacement single...

I have a SuperTrapp IDS II w/ quiet core,that I was running with 6 discs. I put my stock silencer back on and I'm sooo happy with the quiet that it's staying. (been a bout 2 years now). I really couldn't feel the difference , in a "seat of the pants test". The only real benefit for me with the SuperTrapp was the weight savings up high. ('bout 8 lbs)

thanks
Yup, I took Jay's old motor and built the first 780 2 years ago which is still in my main bike. It's never been apart since the original build, still runs very strong and doesn't use any oil.

I'm thinking of raising the handlebars through handlebars alone, not risers.

Anyone happen to know how much higher the CR high bar style would ride over the stock modern DR650 bars? I've measured based on specs I've seen, but it looks like they wouldn't be enough of a rise to justify those over a higher design if I wanted to avoid risers.

Oh I get it. I was trying to explain that HP doesn't have all that much to do with how the exhaust is restricted.
The point is that a bunch of small pulses can slip through a restriction easier than one big pulse.
And of course a big pulse takes more "processing" inside the muffler to get the required 80dB sound level.

This applies to intake through the airbox too which is why the DR responds so well to opening up the airbox.

CR high bars will be about 1/2" to 3/4" taller than stock DR bars. Not much but enough to feel the difference.

Thank you, I'll probably go higher with some other bar bend then.
