I did a quick comparison when I added the steering stop, but I think the YZ490 might not work on a standard XS. The stems and bearings are almost identicle, but the threads on the YZ490 stem that hold the upper bearing in place are not as high as the XS so I don't think you could get the bearing secured. I haven't tried it with new tapered bearings yet (that would be more final), but still have welding to do and blasting so I don't want to install them right now.
Now, if I can get this XS to go where your XS has been I'll be a happy camper
With all the mods you're doing, it should run ring around my old beasties
Tyre choice has a lot to do with dirt riding - well pretty important on the blacktop too!
So there's not enough length of thread on top of the stem of the YZ?, that's a real bummer, hoping to find a front with easy adaption onto the XS frame, still looking - might start looking @ roadbike frontend options
