The 2002 is completely stock.

Maybe you have other issues?
+1
A properly tuned jet kit installation will return about the same fuel economy as stock

+1 +1 again and multiplied

That's what most people don't consider. Did over twenty carb'd bikes in my off-road addiction, and ten carb' road bikes . . . and in EVERY one of them the consumption at a similar straight & level speed is the same. (Or so close you can't tell).
But, and this is a BIG butt, that fuel-consumption adjust-o-meter twisty thing on the right handlebar end makes it seem like a well calibrated carb is a toilet flush. Not really. More power comes from burning more gas/air . . and from the indications I've seen on this site, DR Riders are not generally against making those shit-eating grins inside their helmets. You are ALL guilty of this. Don't lie. You know it. I've never met you guys and even I know it.

Anyway, this is my first post here. Just finishing my DR minor 'got-to do' things. Converting over from a LOOOOOOOOOOONG string of XR-600, 400, 250 CR250 single-track enduro run. After 10,000 miles on those I'm liking this DR.

After jetting and exhaust, I'm still getting ~ 48-50 mpg. depending on how hard my right hand twists.

I missed this the first time around. This is a dead giveaway that you already had a carb problem. Float orings or float needle. Possibly (but unlikely) a hole in the vacuum diaphragm in the petcock.

My 03 was getting bad mileage, come to find out there was a hole in the petcock diaphragm, pulled the vacuum line off and it was full of gas.

Fuel screw was about 2 turns out, which i changed to 2.25 before leaving work today as it was running a slight bit rough. 2.25 was better.

My setup before all this was stock carb with aftermarket fuel screw (not sure how many turns out it was), stock airbox and filter, stock header, unknown aftermarket slip on with integral mid-pipe.

I ran out of fuel on primary after 70 miles (with screw 2 turns out for 65 of those miles). Really surprised me as before i was getting 95-105 on primary. Switched to reserve and found nearest gas station. Filled up and it was 72 miles on 2.5 gallons, filled up to the bottom of the filler neck. Putting mileage around 29 mpg. I was getting around 40 mph before. This is pretty much all slab right now, varrying from 35 to 60 mph, commuting to work.

So i figured i would lose a bit of mileage, but not a 30% drop. Is this normal, or if not, any ideas how to improve this? I see people talking about mid to high 40s on here, so figuring something ain't right.

Thanks much.
What about the Needle? You haven't mentioned it at all. Most important element. Get the Dyno jet needle: #3138.002 (US model)
If you still have the stock needle ... then THERE is your problem.

When you say "air box top removed" ?? How did you do that? Normally, a section of the air box top is cut. I would follow the "Jesse template". It works. If you have, for some unknown reason, removed the air box side cover ... put it back on.

I'm not a K&N fan but I doubt that's your issue.

Try this:
Main: 155 (DJ jet)
Needle: 3rd clip down from top
Pilot fuel/air screw: One turn out.

Having the Pilot fuel/air screw out too far wastes A LOT of fuel. Turn it IN and lean it out. Sure, it will run a bit rough at idle but your fuel economy will be MUCH BETTER.

Good luck!

Welcome to DR madness! I'm a long time Stonyford/Fouts Springs rider, lots of JackHammer finisher pins. Retired from competition now (B rider). I still ride up there from time to time ... or over at Middlecreek. Love the Foresthill area. Awesome!

What sort of riding do you intend to do with your DR650? Dual Sport, Travel, dirt? All of the above? Post some pics of your bike as you get some mods done.
I've had a few Hondas too: XL600R, XR400 (baja kit) XR250. My race bikes were mostly YZ250 two strokes (enduro-ized). Current dirt bike (old mans bike) is a WR250F and CRF230F.

Well, after approx 15k miles my DR decided to spring a leak! I got oil everywhere! I was riding a lot of dirt roads Sunday which caused the dirt to stick to my engine drawing my attention. I checked all the oil lines, cooler, valve adjustment covers and they are all dry. Leaves the cam chain adjuster and/or base gasket (which is the metal multi-layer one). I was thinking cam chain adjuster but I have oil on the front of the cylinder fins! Could the wind blow it around everywhere? I guess I am going to have to clean it good- fire it up and drink beer until I see a leak!

I am going to have to fix this- I can't point at oil leaking H.D.s and laugh when mine is also marking its territory!

Just wanted to say thanks again for the advice on the starter motor.

I was thinking 'worst case' and got stressed/not thinking clearly. The brushes were short and the metal bracket they are encased in was rusty. A little elbow grease and sanding and the DR was up and running again.

Sold it this morning. Finished with the South American leg.

What is the availability of DR650s in Africa?

Its Starting to Come Together - CDT Montana to New Mexico 2012

Greeting Fellow Inmates!
Today I bought a Montana GPS to add to the DR for my CDT ride this summer. Until I bought the GPS and loaded big dog's route on it, the ride did not seem real. I almost have the DR farkled beyond belief and have everything I need to go. While it is still several months to go yet it seem real now. Oh I bought a rippin camera also, Sony HX9. I have been reading this forum since Christmas 2010 and though this forum this ride is going to become reality. Thanks to all for all I have learned about my DR, so I have just enough knowledge to get out there and get in trouble! I still have a lot to do before I go, but it seems real now. Thanks Roger

Yamaha was so nice not to import this baby..................saved me thousands of dollars with my DR purchase last summer. Got tired of waiting and like many here made the DR fit my need easily.
