    I will never know the difference as the bike was decapitated when I got it. It is exciting to have it all dry fit, now for grease and wiring the birds-nest up without the instrument cluster.

    It was a Contour Roam. Somebody posted an Amazon link awhile back and it was only 70.00!

    Neither of those mods should require any further shimming of the needle. My advice is to make the changes in steps then analyze how it runs after each. That gives a better feel for what changes really occur for each step, plus as much as these changes are interactive, sometimes they balance each other out in some ways.

    A 58 pilot is rich for low altitude, much less for 5-8k. I have the mods and running 55 now after changing from a 50. 50 was a bitch starting in cold weather, 55 made a big difference, and I actually dropped (unshimmed) my needle which fixed a slight top-end richness I was experiencing. Now, it's "smooth as budda" all across the board, zippier, and starts much better, although I do use the 'choke'. So if after you make the mods you propose, you still think it runs too rich at idle / slight throttle, then consider dropping your pilot, maybe try a 55. But if it "runs awesome, very sharp throttle response and pulls strong and clean" then why bother taking a chance of disrupting that? BTW, we want our XRLs running a tad rich anyway to keep our engines cool. And I'd rather sacrifice a touch of fuel in the mountains than deal with the hassle of an oil cooler (which doesn't mitigate combustion chamber temperature as effectively as a slightly rich fuel/air mixture, anyway).

    There were a bunch of Jeeps coming off the top of Red Cone that day. There are plenty of videos on YouTube that you can see the trail on. Lots of loose base ball sized rocks.

    There are 2 settings on the camera. The better quality setting uses too much battery so I had it on the lower quality setting.

    Just picked up a 2008 XR650L to do the TAT this summer. I know this probably has been posted here somewhere, but with over 3000 posts in this thread I just have to ask instead of spending days sorting thru. Please forgive me.

    Have read about Dave's carb mods for 2003 and prior carbs. What about 2004 and newer? This PO of this bike de-smogged it, but left everything else stock. Stock pipe. Stock filter. Stock jets. It fires up and runs fine, but I have no basis for comparison and know uncorking the intake and exhaust always help.

    So my question is, do the Dave's mods also apply to later models? If not, what are the recommended mods to making it a little richer? The plug shows me it is on the edge of lean. I'd rather start with the filter, removing the snorkel, and doing the pilot/main, but don't know if it needs the disc spacer on the needle. If possible I'd like to leave the stock exhaust, but am fully capable of making it breath a little better without the noise.

    Please enlighten me, or point me to a web page that addresses these issues for the later model XR's. Thanks.

    Do ALL of Dave's mods and then tweak from there. Drill the slide, shim the needle, all of it. It's fine with the stock exhaust. I have a 2008 model and you'll like the change it makes. You can also google advrider: dave's mods and see several comments about it and some of the tweeks guys have done. Also personal preference, but instead of grinding the tab off the needle, I ground the tab off the carb so I could use the tab on the needle as a reference for setting it.

    It was hard to get myself to buy the powerbomb and start modding the bike more, because it DOES run so good right now.......but at 5000ft up you lose a lot of power, especially with machines that don't have that much to begin with, so in the end I realized I needed to do what I always do to my machines up here......mod them enough so they run at least as well as a stocker would at sea level :lol3
    High elevation living sucks when it comes to power sports :baldy

    Thanks for the excellent advice :thumb I agree, I suspect that the bike is just going to run better with the airbox mods and header, I'm thinking I shouldn't have to go into the carb for anything......fingers crossed. I've never jetted an xrl before tho, just wanted some experienced info to help guide me :D

    Hey Jeff!
    I'm very pleased to see you're going to take an XRL on the TAT! I think it'd be my choice if I could have anything. Any way I can help you just let me know. If you haven't seen it already, I suggest you check out the ride report on here by our neighbor and my friend XCrider (Denis). I like how he stitches together a ride report.

    All the carbs take the same mods. But the difference in "uncorking" isn't exactly huge. It does make a difference if you really want to run full-bore, but who wants to do that on the TAT? Not me....

    I agree with your plan of keeping the stock exhaust. While I appreciate the boost in performance, weight savings, and the throaty tone of my White Bros unit, the stock unit is less bothersome to others along the way. It's a benefit to be able to sneak around without people being able to follow you by your sound. And as Dave says in his mod, his particulars apply to a bike that's been opened up, that of course including performance aftermarket exhaust.

    As for jumping into mods, I would be focusing on what particular weaknesses you have personally experienced and wish to address. These guys come a bit lean from the factory in order to pass exhaust emissions standards imposed by our illustrious Federal government. From my experience, what I'd do is exchange the stock #50 pilot jet for a #55, and see how she runs for you. Then based on your anaylsis of the effects of this change, you can refocus your efforts. I'm expecting you'd find this quite acceptable performance to run the TAT.

    What is your schedule & plan for running the TAT?

    I know.... it's hard to keep your hands off the bike when conditions inhibit riding it. :deal

    Oh yeah? Well, from the pictures, it doesn't look too sucky, so I'm not the least bit sympathetic! :bluduh


    The basic prinicples are the same for any bike with a carb. You can make mods to get more air and others to get more gas, Coordination is the key, because it is the ratio of gas to air that you want to optimize for your given criteria. Once you know what affects what, and how, and are able to feel a lean, good, and rich condition, you just make a corresponding adjustment and dial it in. :thumb

    Shouldn't be any difference in model years. I think that may have just been the bike he had at the time to do the mods on. I did all of it exactly as it was laid out on my '08 with no problems and did the TAT through Moab that way. You could take a few extra jets for the high passes as I did have to pay a little extra attention to keep it running, but not mandatory. Who wants to crack open a carb on the trail anyway, unless absolutely necessary. Good luck and have fun!

    I always crank my idle up in Colorado and that helps a lot.

    Will do. I've been reading a LOT of TAT reports.

    I am NOT a top end kinda guy. I don't even like going over 60-65 mph on the pavement anymore. I'd much rather go fast on dirt and in the curves.

    Loud pipes are obnoxious to me, and most non-riders. Like you, I'd rather be in stealth mode in the back country. Plus, I'm a little bit frugal and paying big bucks for a performance pipe is not where I want to put my money.

    I think I'll try the #55/#158 with the clip spacer and see what that does. It is running lean, and is cold blooded. Will go with the UNI filter and maybe remove the snorkel. If I replace them I'll keep them in the kit for the higher elevations, if needed.

    The trip is a graduation present for my nephew. He is 18 and needed a small carrot to get to graduation. We'll start in late June on the Outer Banks, literally riding in the Atlantic. Then head west and take the TAT to Oregon. Plan is to camp the majority of the time. His Dad will fly out to Oregon to meet us. We'll change the sprockets, oil, adjust valves, and put on street tires, then he and his Dad will ride back to Virginia on Route 50, and I'll fly home with the camping gear while they motel it. We're planning 5 weeks out, and two weeks back. Planned oil and tire/sprocket changes in Colorado, then again in Oregon.

    I'm looking as much towards this ride as any I've ever been on. Only it should be easier with no border crossings, and not having to learn a new language! My normal ride is an R1150GS, but I think the XR will be better suited for this ride, especially out west.

    If anyone has great suggestions about the TAT and mods on the XR for it, please let me know. Already have the Clarke 4.7 tank, rear lightweight rack, and a lowering link. Will be adding a bash plate, larger pegs, and some type of rear soft luggage system. Would love to hear what others have used and prefer.

    Thanks everyone.
