I have an 04 660, trans has been giving me grief (high gear jumps out) so I decided to change the transmission.

While apart I decided to do some mods to engine and clutchs. I have shimmed primary 1.5 mm and added an orange EPI spring to the secondary. I want to go greaseless, recommendations on weights? 27 inch Mud Lights. I am also adding a HotCams Mudbuster cam, anybody ever try one? Recommend a higher compression piston?

Looking forward to what ya’ll have to say.
