    Don't waste your time using the injector. Just buy a two ounce bottle and refill it with the bigger quart bottle. The tip of the 2 ounce bottle will tip upside down perfectly into the valve.

    Just put the valve stem of your wheel at the 3 or 9 o'clock position. Put the tip of the injector on the valve stem no need to screw it into anything. Hold it there tightly with one hand and with the other hand squeeze the injector fast and you'll be fine.

    Another method is to remove the tip off of the Stan's injector and remove the core from the Mavic stem (as you have done. Slip the bare Stan's hose over the Mavic stem. IIRC, I replaced Stan's tube with a smaller diameter one that fit both the Mavic stem and the injector.

    Ghettocop, your method sounds pretty good. I will give that a shot.

    I use a similar method but with an infant medicine syringe (get from any pharmacy near the kids liquid tylenol). It takes a few times but you don't have to break the bead and when just adding a little in every few months makes it nice and easy. Rinse with water when complete and I have used the same one for 3 years now.

    I use these 1-oz Luer-Lock syringes. They fit into the valve stem perfectly:

    General Purpose Syringe Medi-pakô Performance 30 Ml Luer Lock Tip - Syringe, Ll 30cC (25/Bx 8bx/Cs) - Mckesson Brand

    A mom-and-pop pharmacy that does compounding will probably sell you one individually. Don't know if chain-stores would sell them individually or not. Wouldn't hurt to ask.

    If you care about the graduations, put clear packing tape over them to protect them. They come off quite easily otherwise.

    Wheat Germ's infant syringes sound easier to acquire -- I wasn't even aware that such a thing existed.

    But I prefer to dismount a bit of the tire and see what's going on in there -- remove buggers if latex, add a little water if the mix is getting gooey.... I just flip the bike over on its back and leave the wheel mounted -- that way I don't need someone to hold the tire off the ground when I go to seat it.

    Just use the syringe, the end fits right into the valve with the core removed and just use the vacuum that's already there to suck the sealant into the tyre by gently squeezing the sidewalls and letting go. This is how I do it and it's easy and works very well and is fast.

    My Stan's syringe is threaded to fit both presta and shrader. I put the wheel at 12 o'clock and thread it on then move to 6 and inject the Stan's...piece of cake!

    Edit: I am using Stan's MTB valve stems.

    HELP Notubes the injector?

    I'm a big fan of threaded injector plus 44mm valve stems. Having the injector pop off the valve and spew sealant is not a fun experience. I hate the Mavic stems also for their short length. I want a stem that is easy to lock an injector AND pump head onto. The 44mm stems are marketed by Stans as being "tubeless road valve stems" while 35mm are for mtb. I use the 44's on all my wheels, mtb and road, as the are fool proof to pump even with a lousy pump head.

    thanks for every ones advices. since i already bought the injector and cant return it. i decided to replace the mavic valve to stan's notube 35mm valves so i can continue using the injector and not buy the small 2oz bottles every time.

    As I posted above, highly recommend the 44mm. This is what it looks like mounted. plenty of room for pump head to lock on.

    The 35mm should be fine. But definitely no shorter.
