What the heck...why do they get adjustable needles?! I have my idle mixture screw at about 1 3/4 and it runs good; figured another half turn wouldn't make it not run. Mine actually idled better at 2 but had rich bog right off idle. It is a give and take with the damn things...

The real question is "Why are ours not adjustable?" and "Why is there a stupid aluminum blanking plate over our idle mixture screws?" This is the US EPA's approach. Assume we're stupid, then look the other way.

I applaud reducing pollution, but the EPA's approach is .... and nanny state bureacracy.

Also, check to see that the choke cable is set properly and that the black, plastic housing is screwed on correctly.

Perhaps one of the carb guru inmates can give you better direction than I, but just some food for thought.
Will def recheck carb boots. Was a bitch to get it back in. Maybe I futzed the fit. Thanks

That's why blocking the snorkel might be helping. Is 2 1/4 turns normal for the fuel screw? I thought it was more like 1 1/2 turns....
The throttle stop as I see is the big screw on the left of the carb? It's just a mechanical screw that prevents the throttle from closing completely isn't it? I tightened that one all the way up but the little bit that sticks up only extends about 5mm. Not enough to affect the idle. I can extend the main housing but this still seems like a hack and not the root cause.

Will try reducing the turns. I was working from the BST Bible which says 2'ish but they're using the KTM needle.

Thanks!

My rear 705 is just about shot.. I have a new one in the garage I need to swap on. Might do that tomorrow. That and check all my motor mounts to try to figure out that weird vibration. I also wonder if the cam chain tensioner might not be doing it's job, since it's the automatic (stock) one.

Weight is your enemy off road, why not put a 790 kit on a DR and have a light weight powerfull bike $680, that's what I plan.

Except put any weight on the XR and the subframe fails, and the 690, bad vibrations, and anyone like lots of and hard maintance? Get a DR and put a 790 kit it, it will blow the rest away.

It's a good shock just upgrade it. I put a $900 Wilbers with all the options on my DL1000 it lasted like 3500 miles, F expensive shocks unless you are rich or you race.

3. I'd bet Pilot Jet is clogged. Pull it out and clean it and flush out the circuit below the jet too.

4. Make sure no crud below float needle.

Good luck!
Yeah forgot to mention i'm in Oz where we can be trusted with needles

I'll double check the jets but cleaned each one by hand and each hole with tiny dental brushes (work a treat) and pretty sure each one was sparkley before it went back in.

The circuit however may be something to look at. As I don't have a ultrasonic cleaner setup any tips on getting into the circuit to clean things out?

Float needle is spotless.

There's no fuel coming out the overflow (as it has in the past) and if I turn the drain screw fuel comes out so the float bowl appears to be filling and shutting off correctly. The rubber tipped float needle looked fine and was thoroughly cleaned. If the float wasn't set correctly not allowing enough fuel in i'd guess that the problem would be more stop-start than affecting idle. Because there isn't much vacuum at idle fuel level makes a big diffrence in how it pulls the fuel in. Once you crack the throttles open you are not using the idle circuit as much and are moving onto the needle.
By blocking the air intake (causing it to idle correctly) wouldn't that reduce the vacuum as well? With no throttle and blocking the snorkel it comes good by itself which to me seems like it would be getting enough fuel via idle. Very odd.

But if it's getting too much air I would have thought adding choke would improve the fuel air ratio making it run closer to correct. Currently it seems to make no difference except prevent it from starting.

These things seriously work by voodoo. After checking air leaks and reducing fuel air mix i'm buying a chicken just to be sure...

Greystoke,
Carbs aren't voodoo. I promise! Your throttle stop screw is your exact problem. Yes, it is just a simple mechanical screw - probably the simplest thing on the carb. You say that yours extends 5mm and does not affect idle. Ding ding ding! Your idle screw SHOULD BE affecting your idle!!! FWIW, my idle screw extends out almost exactly 1 centimeter and my bike idles and runs quite well. It has some room to extend further too, if necessary.
Don't overlook the simple stuff when dealing with carbs!

Be sure to stick something thru the pilot jet when you're in there. It's a very small hole, pics below.

The circuit however may be something to look at. As I don't have a ultrasonic cleaner setup any tips on getting into the circuit to clean things out?
Brake or carb cleaner squirted thru the passages will work; wear your safety glasses. One of them kills rubber pieces IIRC

These things seriously work by voodoo. After checking air leaks and reducing fuel air mix........
Starter fluid squirted around the carb while running will raise rpm if there's a leak. It isn't good for piston walls and things, so don't go overboard.
Pilot jet.

A simple check, stick a coin (or more) in here to see if it helps.

Travel Tools

I briefly searched the forum and google for this with no success, so here it goes:

I just recently purchased a DR650 down in Orlando, FL. I will be doing a fly and ride to bring it home to Southern Wisconsin next weekend. I hope I won't need any tools for my trip home, but I tend to not leave the house with some kind of tool set to help me get through a bind. Unfortunately, I haven't had a lot of 1-on-1 time with a DR650 before buying this one so I'm not very familiar with the "tools you don't leave home without." Obviously I'm aware of the basic 10mm wrench and socket, but to help me out... what tools do all of you never leave home without?

Thanks!

Among the standard pliers and screwdrivers, I carry tire repair stuff. I have a small bicycle pump, tire Irons and a patch kit. Also on my front fender in a tool bag made for that spot I carry a 21" tube and a small set of jumper cables that came from Aerostitch. The DR is the first and only bike I ever owned that doesn't have a kickstarter. Scares me to death. I've never needed them for myself, but have helped several others. (how old is the battery on this bike you are buying?)

Did you know the DR has a fairly complete tool kit already? You need tire irons, spare tubes and a pump as well, though. And an adjustable wench.

Meat clubs for hands

I don't think, I have overtly gargantuan sized hands but I'm struggling with comfort on my 2012 DR650. I always wear gloves, in summer I wear mechanics gloves and for winter I have a nice thick pair of snowmobile gloves. The bars on the DR are just a bit narrow so I'm looking to replace them. As I collect parts I also want to find the right size and fit had grips.

In the my summer gloves the palms of my hands hangover the outer bead of the grip a 1/4 to 1/2 inch, even when I keep my hands right up against the inner bead. This is very pronounced in my winter garb. The grips also tend to be skinny. This is to say my fingers wrap around the grip and nearly touch my wrists. I'm only 5'10 230lbs so I'm not unusually big, although; I do have long gorilla arms. I can't be the only person with similar problem.

Can someone recommend a wider thicker grip that will allow me to tackle obstacles while knowing I have firm grasp of the handlebars?

Thanks

The big DR push-starts easily enough.
