250r rotor and hub on 400ex?

[childert79]

I have a 250r lsr rotor hub that I'm wanting to put on my 400ex. If I get a 250r rotor will it fit with my 400ex rear end? Also need help with seperating ball joints. Any advice/replies is greatly appreciated.

I believe the 250r rotor is smaller you will need to also have the caliper and bracket, you can use a separator tool for the ball joints, about 25 bucks at your local dealer... or you can smack the spindle with a hammer where the joint comes through but it really dings em up.

Thanks a lot for he quick reply. Ill pick up a ball joint seperator later.
