    +1 on running Tubeless - that's definitely on my list of up-coming farkles (if I could ever find a round tuit, I'd be set!).

    As far as air off road goes, I carry a cheap air compressor that I run off a cig plug that I added to the beast. Actually I have a SAE connector wired to the battery for a battery tender and an SAE to cig plug adapter that I found at wallyworld for $5. The compressor plugs right in and works great.

    BTW, I had one of the small slime pumps for a while and took the case off to make it even smaller but, without the case, it really gets banged up when going off road and got pretty much destroyed in one trip. I just suck it up and carry the $15 compressor that I found at Target with the case on it so's not to find a busted compressor when I need it most. Takes up more room but worth it.

    My 9 year old kid rode 93.7 miles of mixed offroad terrain, some over 10,500 feet on my wife's XR100R today. He said he would like to ride with me and that he could do it. And he did! She lost her privleges to that bike. :D
    It only used 1.07 gallon of gas.
    He'll probably want my XRL next. :1drink

    Completed Dave's carb mods and have a few questions for the CV experts.

    The bad flat spot I had off idle when I whack the throttle open is ALMOST gone.
    In the past I've raised the float level a tad to richen up the off idle response.
    Float adjustment is not possible with the XRL carb....so will clipping a coil or two off the slide spring help? Or will further enlarging of the two slide holes yield positive results?

    Have opened up air box, aftermarket exhaust, K&N filter.
    Current jetting is 150 main, 60 pilot with air screw 1 1/2 open.
    (couldn't find a 55 pilot anywhere).


    thanks

    That is awesome, your a awesome dad.
    When my son gets his MSF course and License. I am going to have to lock My XRL so he wont take it to school. He is almost 16 and he can flat foot my bike.

    Hey Junkyardroad,

    That is frikken' awesome that you can share riding with your son. I have 4 daughters and they just aren't into it. Too much pink and girly girl crap....uugghhhh

    I do have my first Grandson now and am awaiting his arrival into the dirtbike world. I can hardly wait! I see many, many, many weekend, weeklong, etc trips completely centered around the twisting of the throttle!

    You are an awesome dad and a true inspiration. Enjoy the times, they will be with you forever!!! Great looking kid, I might add! You gotta be proud!!!

    Nasty, I am not quite sure if you mean how the system physically works, or how it works as far as an answer to the tube dilemma. I found the whole tire mounting with the system actually easier than a tube. Fast, easy, efficient and that was on a rear 150 MEFO explorer II, which is a VERY tough tire. The sidewall seems every bit as tough to mount as the Terra-Flex, and I got it mounted up pretty quickly. I do install my own Terra-Flex's as well...

    So far the system works as advertised with zero problems at all. I carry a mini hand pump with a built in gauge that goes up to 150 psi. for the inner (innertube??? for lack of a better explanation?).

    I can see being completely done with tubes for me!!! The $100.00 price tag is a little steep initially (I have 3 dirtbikes with extra wheels for all of them...), so I have experimented with one set and am quite pleased. I will be converting all of them soon. I still will be trying a 17" wheel off of an adventure 1200 GS mounted to a cush rear hub with a TKC-80 tire, but will probably wait until late fall or winter for a Mexico trip to try it out. I am ecstatic at the thought of a knobby that can get 5k (or more) and tubeless as well. While the tread is not quite as aggressive as some knobbies, I think the size will make up for it. I was able to get a little lift in the deep sand on the 1200 GS Adventure, so I can imagine how the 650L or KTM 525 will do. Rock traction was acceptable as well. There is always a tradeoff with anything. I think acceptable performance on the trail combined with long life will take away a lot of the hassle I have had in the past with staging tire changes in Mexico. Shipping tires to a hotel, consulate, bike shop, etc. then getting there and finding there was a problem, settling on a shit tire, etc, etc... If I can make a trip on one set of tires with ok performance, that will be quite fine with me!

    I am not sure where I will be going in Mexico, so I don't know if I will try the cush/17" set-up on the 650L or the 525. Baja would be the 525, interior or Copper Canyon would be the "L". Now, I need to find a front tire that will have similar mileage life. Maybe a Metzeler, Pirelli or Dunlop Desert????

    Now I have a new quest!!! Front tire! Suggestions appreciated.

    RavenRanger, good idea, the extra space is probably not worth tearing up a pump. I was considering relocating the battery to the airbox and making a pump/tool stash spot on the "L" where the battery is now... won't work on the 525 though... Great advice

    Wattner any comments on improved handling, braking, accel, suspension performance etc? I am seriously thinking this might be my next tweak.

    Yeah but the foam inserts are heat sensitive and don't last very long before degrading.

    The tubeless system is so much more elegant.

    Hey Wattner - did you use the stock rim lock location and air valve location on the XRL rims or did you drill out a new hole in the suggested location? Assuming you moved it, what did you use to fill the stock rim lock hole?

    Now that you have the tubeless system have you thought about experimenting with creating your own? Looks like they're using a high pressure bicycle tube to seal the spoke nipples but it's hard to figure what they're using for the red divider between the high pressure tube and the tire's air chamber.

    I've thought about experimenting with putting in a valve stem and sealing the spoke nipples and rim interior with an elastomeric coating similar to some of the new roof coatings as a poor man's tubeless system. Thoughts???

    It could be a rich or lean flat spot, It's a pain but I'd try fine-tuning the needle shim washer thickness.

    I assume you have a 15x or 160 main jet, not a 150...

    If it's a rich flat spot, riding without the airbox cover should help it, if it's a lean spot that'll make it much worse.

    When I whack my throttle open I suspect I'm a touch rich, it burbles for a brief moment before pulling but the power doesn't go down and then back up, it just pulls a bit harder, it clears, and then pulls as it should. I tolerate it because for my riding, the control seems good and I'm just too lazy to mess with it.

    I envy you. My boy is 9 as well but he lives with his mom, and she is against it. So much so he doesn't know how to ride a bicycle. :cry ....

    I bought him a ZR50 to learn on but I am worried due to his lack of two wheeled experience. Cherish this

    Yeah but the foam inserts are heat sensitive and don't last very long before degrading. Agreed, and the balls are cool, but a PIA to install and may pose a problem for away from home tire replacement if you need extra balls or something The tubeless system uses a cheap and easy innertube off of a bicycle or something

    The tubeless system is so much more elegant.:clap

    Hey Wattner - did you use the stock rim lock location and air valve location on the XRL rims or did you drill out a new hole in the suggested location? I actually installed the front on a new wheel for the CRF front end, and I drilled the new wheel. On the rear, I have a non-stock SUN rim that I drilled with no stock hole. If I had to plug a hole, I would use a small piece of aluminum flashing or flat stock that is slightly larger than the hole and use a Marine Silicone to seal it up, filling the hole on the bottom and smooth to the dimension of the rim.Assuming you moved it, what did you use to fill the stock rim lock hole?

    Now that you have the tubeless system have you thought about experimenting with creating your own? Yes, I have... I am experimenting with this system to see if I can improve it or not.. So far looks great!!!Looks like they're using a high pressure bicycle tube to seal the spoke nipples but it's hard to figure what they're using for the red divider between the high pressure tube and the tire's air chamber. I am assuming that and the plastic and steel components utilized that create air inflation system is what makes theirs proprietary and expensive. It really looks like there is way less than $10.00 of hard goods for the unit, plus the stickers and divider that comes with it. Looks like a cash cow if it gets widespread acceptance.

    I've thought about experimenting with putting in a valve stem and sealing the spoke nipples and rim interior with an elastomeric coating similar to some of the new roof coatings as a poor man's tubeless system. Thoughts???Absolutely!!!! I actually have looked into this quite extensively and will launch my version sometime along with an entity that I created some while back dealing with specialty Motorcycle needs. The R&D takes significant $$$ and time, I just am time poor at the moment. There are several obstacles to overcome, and I have attended to most with favorable results. There are however drawbacks to the elastomeric method and I am hoping to get all the bugs worked out for my own use, much less trying to market a finished product. I like ideas and sharing ideas... My biggest concern (and may be no concern???) is a rim lock to prevent the tire from slipping on the wheel while sealing as well, another is a field repair should a tire tool or a large nail or object protrude through the tire and damage the elastomeric. I have had objects in tubed tires that may have torn it up (and will the Nuetech tubliss system as well..)....

    Let me know if you need a test-rider!

    Meanwhile, I'm going to continue to experiment as well because I agree that an after-market retro-fit tubeless system is a great idea.
    :clap

    BTW, here's a write up of someone converting a mountain bike to tubeless that looks interesting.

    Right..my typo, its a 160 main. needle shim is .025". I'm at sea level.

    Air cover trick is going to be tried this afternoon.

    What effect does cutting the spring have? Cutting 1 1/2 coils was part of the "carb fix-it recipe" for my KTM LC4. That thing rocked afterwards.

    Thanks again!

    Well, it's a mixed bag. It lowers the preload on the spring, but the spring rate goes up, although it should be more open for any given amount of throttle with less preload.

    The stock CV carb is fussy, you might do it and it works great, or it might suck.

    I'm learning this right now. I can't seem to get mine purrrfect. Lately the issue I have had is that I can't run at an even throttle at lower to mid RPMS. It sputters. It's like I have to have the throttle off or on for it to be smooth.

    There was someone several pages back who was looking for a decent XRL for not too much $$$. (Sorry, I'm to lazy to search back through for it.)

    I happened to see a decent looking '94 on my way to the grocery this evening, got the info and I've stuck an ad in the flea market for it.

    I just bought this bike tonight: http://bloomington.craigslist.org/mcy/1272065659.html

    It runs, but it needs a LOT of work. All of the electronics have been ripped off and it smokes horribly bad. It shifts through all the gears and stuff though. I suspect that it has a blown head gasket because its leaking oil from the head and from there the entire inside of the exhaust is lined with oil so bad that it spits oil out of the exhaust. Also, the gas tank is rusted so bad that it has actually rusted apart. So, it needs electronics, a wiring harness (maybe), a head gasket and probably some rings, a gas tank, a seat cover, and some other misc. stuff. you can tell that it was abused, but the guy who i got it from had it for about a month and took decent care of it.

    I think I could do one of two things with it...Make it a runable bike and fix whats wrong and make it safe to ride. I think that if I invested about 6-800 bucks in things that it needs, I could have a good bike on my hands. OR I could strip it and sell it. what do you guys think?

    The older XL600LM sold in Europe had tubless rims. The rim had a raised ridge where our spokes go and it was drilled for the spokes. Not sure they could be fitted to our hubs or not? The rear is a 17" rim also.
