I race the Texas Harescramble Series and just bought a 426, I had an XR400, I cant seem to get this thing to handle in the tight woods, does anyone have any tips, ive dropped the forks in the triple tree and shortened the chain as short as possible, its killing my laptimes, but Im not sure its not just me. My XR was much more forgiving but I dont think its the power difference thats the problem I just cant get it to turn.

Are you running stock suspension settings? I had to soften mine up a bit to handle tight single track stuff. Plus I got rid of that junk 739 front tire for a 756 (or 755) then I put in ALOT of seat time learning how to handle the beast, powerwise, so it's hard for me to believe the 426 doesn't put out a TON more power than the XR (although I've never ridden an XR400). Also, try sitting almost on the gas cap in corners, which is something hard to do on the XR.

I second YZWrench's comments. I couldn't get my 400 to turn until I did both. I dumped the 739 and put on a 756 that I'm very happy with. When transitioning from standing in a straight to sitting for a corner, I use the momentum from braking to move my body forward on the bike. Sitting on the gas cap is about right!

I think if you play around with sitting WAY forward you'll find it really helps. You have to ride the YZ's aggressively or they won't turn :)

Thanks for the input guys, Ive already changed to the 756 front and rear, I had an aloop kit on my xr which allows you to get up on the tank, Im sure Im not doing this on my yz, I guess I need some more seat time. Thanks again

-Slide the forks up in the triple clamps 10mm
-increase fork rebound(slower) to keep the front down, and maybe decrease compression a little
-Set the rear sag to the minimum for your weight, making sure it settles under it's own weight no less than 1/2inch
-rear shock - rebound adjuster carries over on compression side a little and firmer adds precision at low speeds.

All these changes will keep the front end down and back up to help shift your weight forward in tight corners( a compounding effect). They will also reduce high speed stability as a trade off.

Put lighter weight fork oil in the forks. It makes them more responsive to small stuff. You will have to reset your damping though.
