YZ 450 cam, need help
Posted April 15, 2003 - 10:38 AM
Any advice is appreciated.

As far as the power goes the YZF cam moves the power more towards the top end and takes a little away from the bottom end where you really feel it. Your bike's not any less powerfull, it's just the power is directed at a different RPM range. I prefer the WR cam timing, it feels more torquey to me.
Am I in the ball park TTers?

If you rotate the old cam one tooth forward then you have the old fashioned YZ timing, If you want 450 power (sort of) you Install the 450 YZ Cam itself.
In other words I think you have your cam in 1 position off, rotate it back to stock position according to the pictures in the pdf file, not the instructions.
Correct if I am wrong folks...This guy needs some verification from some one who has done this.

I'll take the cam cover off and check everything. I used the pdf to install it but I'm not sure if I looked at the lobes after I put the cam tensioner back in. I think I'll order the next size larger shims and see if that helps.
