DIRT BIKE mag. auto cam

the 426 has slightly different cam characteristics than the 400s, doesn't it, and dirt bike is saying that it drops right in like a bolt on mod, no problem???
anyone else have an opinion. i think that dirt bike needs to send a rep over to hang out around thumpertalk before they go posting anymore "focus on fourstrokes" advice.

No problems yet have been posted! Spoke with Racers Edge and they put one in a while ago with no problems!

Plenty of positive reports about it... there are changes to the head, no one doubts that... but they do not affect the cam as such... there is a small issue, but if you read the post over on the YZ4xx forum, you will see that it seems to make no difference...
It is basically a bolt-n-burn mod... very little to do except to add slightly larger shims to compensate... while you are in there, check the inlet valve clearances, but otherwise, there is no major alterations needed...
