change cam bearings when fitting new cams?

I have a 2010 Super Glide Custom that I want to fit with aftermarket cams.

I am still looking at which cams to fit, I do a lot of 2 up riding so I am looking at something that suits that purpose.

I already have the Stage 1.

Changing the cams. won't be a problem mechanically.

The bike has only done 7000 Klms. so is there any need to change bearings?

It isn't that bearings are matched for any particular cam.

 Frank, you wanna change those factory bearings for "torrington" bearings ........................the following link will explain why.........

Burto, Thanks for the link.  Point taken.

Will definitely change the bearings when I decide which cam to fit.
