Yes, you would definitely notice the improvement going from the stock muffler to a Staintune. Probably good for around 3 HP which doesn't sound like much until you figure that's nearly 10%.

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.
I like KLR's just fine. They need some TLC and good set up just like the DR650 does. Both are fine bikes for your purposes. The KLR is roomier and in stock form better for carrying stuff on or a passenger.

For a DR650 I would try for 2005 or newer. Buy from a "mature" rider if possible and preferably not a former Hare Scrambles racer Ride the bike and do whatever you do to check out a bike ... or bring a PRO along to help. Listen to motor, shift gears ... blah blah blah.

Look for tell tale signs of crashes or abuse ... like messed up engine side cases, bent levers or bashed in frame rails under engine, or dented rims, wobbly wheels, or big gashes under swing arm. A worn out chain, dirty oil or dirty air cleaner could indicate bike was not cared for. Look for mods improperly done like rerouted cables/wiring. Other than that? Consider the seller ... and who he is.

Other than those few things DR650's are pretty hard to kill. Really tough motor, requires little maintenance, very fun to ride once set up correctly.

A newer, low mileage bike is always better. But keep in mind a 9 year old can disconnect the Speedo cable so mileage may not tell you the whole story. Lots of really good aftermarket items to make the DR a MUCH better bike than stock. A better seat should top list of improvements, IMO.

Have fun.

It took a few months, but I finally got my ugly stock '06 DR to look less like a giant banana :

thanks Jeff,

While your on the forum, I was curious if you ever bought Jays (jaminglobal) former motor which he blew up but was reconditioned just prior to his misfortune??

It would be good to know if this motor got back up and running and I remember reading you were going to buy it?? Not sure if you did though.

thanks

Thanks for your offer, however I need to pass on installing an aftermarket exhaust canister. It would have been interesting to see how much the OEM setup could be improved with little more than the cost of jets and airbox alteration, and maybe create a kit for those of us who want to maximize the motor's efficiency/effectiveness without the cost of expensive aftermarket exhausts, for those DR riders who are generally cheap bastards such as myself (owned a KLR before the DR).

And settle this jet needle dispute between Derek and Jeff.

I like the exhaust tone of the OEM canister, my days of upsetting the neighbors with loud exhausts are over. Plus, now it's ME standing in my front yard shaking a fist at the Harleys that roll by with straight pipes!

Appears you have a good candidate with the appropriate exhaust living in S.F.

Lex

Is it cold in here?

There is ALWAYS shrinkage in colder climates!!

I get it and that's the way I feel too. Right from the start, I just ground down my stock retainer so the chain wouldn't contact its outer circumference when the 14T sprocket was fitted. Swapping and changing front sprocket sizes has never been an issue using stock retainer like this for over 40000km. Always use blue locktight on the three retainer bolts because they are soft and don't take much torque.

The temp differentials between running and ambient is big enough without taking freezing style temps into account.

We may have a couple of overnight <0*C temps per year and both my DR's have had loose NSU screws (one had one missing)...

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.

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.
