Going to YZ timing is a very common and trouble-free mod. The really hot setup now is to switch to a YZ 450 exhaust cam. You gain the benefit of auto-decompression. Click the post for this mod at the top of the YZ 400/426/450 forum to check it out.

I have yet to do a mod to my bike that is permanent.
*WR to YZ timing (reversable)
*'03 YZ cam (Can take it out an put the stocker back in)(NEVER WOULD DO THAT! But, I can!)
*Grey wire (Wire removed from connector, not cut)
*Jetting (leaned out all aspects of carb jetting. Runs much better, all can be replaced with stock settings.)
*JamesNOW! (This insert goes on the bell housing between carb and airbox. Can be removed. Again, NEVER WOULD, but could.)
What am I trying to say? All of these modifications are 100% COMPLETELY reversible, and none of them seem to affect reliability of your bike! Do it! Do it all! If you don't like it, you can always go back, but you will not! These bikes run great out of the box, nobody argues that. They CAN RUN BETTER! MUCH BETTER!
