Is the YZF 450 cam out of a 4 wheeler the same as the bike ?

[jecsr]

I have found one at a pretty good price. However, can I use it on my 426 conversion ?

They are not identical to the bikes, but can be used just fine on the 426.

You can just buy the Hotcam with the auto decomp... I did works great

the YFZ cam is the same as the WR cam,

Do a search here and you will see that a few people tried it and ran into the same timing and decomp problems as the wr cam.
