If I run a YZ pipe on a 2001 Canadian WR, (no throttle stop, grey wire, or airbox lid) what jetting changes should I make. 0-2000ft.


Any input would be appreciated.

P.S. Is the Canadian carb the same as the U.S. version? I know the stock settings are different.

If it were me I would just run YZ jetting, since for all practical purposes you now have a YZ motor.

My setup:

'01 WR426

throttle stop cut
grey wire disconnected
no airbox lid
YZ cam timing
White Bros E-Series "Hawkins"
FMF Powerbomb SX
mj: 170
pj: 42
~ 1 1/4 turns
ELN #4

previously I ran-
pj: 45
~1 1/2 turns
DRR #5
Which worked pretty good, but the new setup is better.
