For cast wheels you only ned to get tubeless threaded valve stems. If you order tires online from a place like Motorcycle Superstore they will also have the valve stems. So does you local NAPA or local MC shop. In certain instances you may have to drill out the hole for the new valve stem a bit.

Sounds easy enough. Thanks for the tip. Any reason I should not convert to tubeless? I was going to stick with tubes cause that seems to still be a good system in my book, but the more I read online, the more seems like tubeless may be better so if needed, I could potentially do an on the spot plug-repair of I got a flat (with a plug kit, and maybe a small Co2 bullet thing)?

Groover, just for the record, Pirelli Sport Demons are bias ply tires.  If I had cast aluminum wheels, I'd get sealed valve stems and go tubeless, although I don't hate tubes.

Good deal, thanks again. I must have missed it somewhere that the Pirelli's were double-ply. Would this be an applicable stem? Any good ones you guys are aware of?

Your on the right track but you need to measure the wheel thickness where the stem will go though and allow another approximately 3/4 of an inch for the rubber, nut, washer and valve cap. Also measure the diameter of the hole and get something that fits without drilling the wheel.

Ok, thanks for the reply and tips. I think I'm now 99.9% convinced to make the switch to Tubeless!

Do it, you'll like it!  :)

I converted mine a bit over a year ago.  I had to turn down the flange a little to fit in the recess but that was it (I would not do anything to the rim).  I also did not use the rubber 'gasket' under the nut.  I just used the one inside the wheel (between the flange and the rim).

Shinko SR740f is avaliable in 100/80-16.

Mine are 110/90-16.  I don't like to vary from that even though those will probably fit.

Up or down one size is not uncommon. If you measured 5 different manufactures tires width I'd bet you would find 10mm of variation.

I would bet you are right.  When  my current Sport Demon wears out I might have to try one.
