im thinking of switching to a crf airbox (i think its got the 2005 250X on there now)

do they all bolt up the same
do i want the years before they went to dual silencers
anyone used a gen 3 airboot on there gen 4? of course gluing it real good so it dont leak

might get a whole subframe/airbox.... if the price is right

im after a setup with more room so i can put filterskins on in less than 3 hours, also hoping it might let less dirt in

I'm pretty sure your SH came with an X subframe. The 04/05 R subframe is different. I don't know if an R airbox will fit an X subframe or not. I'm running a gen 1 boot from a 97 - 99. I don't think your motor is rotated to the same angle as mine, so a gen 2 boot would prolly work better, the gen 1 is longer. I posted all the lenghts in the AF section at cr500riders a couple years ago. The older boots are much better and only $28 new. You would need the Dring too which any steely 91+ will do it.
