Question for 426 owners w/yz125 airbox.

I did the mod last fall. Rode for the first time yesterday. Seemed to run well with maybe a little more low end. Did you guys re-jet for this mod? The 125 airbox is much more open and the filter cage has no screen. I just don't want to be lean on top.

i hope you're running a flame proof filter if your cage has no screen. a friend of mine was trying to start my 426 and it backfired and caught my filter on fire through the screen.
