Even with the bike leaning on the kick stand you shouldn't get any fluid loss. The manual will tell you to replace the gasket but i've had my derby and primary cover off 3 times now and still haven't replaced the gasket - no leaks. Just follow any torque sequence listed in the manual and you'll be fine.henryjw1 said:Kinda new here. I want to replace the derby cover on my 06 Ultra. Is there anything that I need to know?? Is there a gasket to replace? Any fluid loss, etc.?? GREAT FORUM!!!!
