Decided to upgrade my exhaust on my '06 400ex.  Bought a HMF performance slip on with Uni air filter and an HMF jet kit.  Slapping on the slip on was pretty straight forward, but I've never rejetted a carb.  After pulling plastic and bolts all over the place, I finally got the access to the carb.  I was trying to be careful but I ended up losing track of where some of the hoses/tubes go.  One ran down towards the ground by the back wheel swing arm, and another is relatively short but I cant find where they may have come detached from.  Any help or pics would be great guys!  

Also, do I need to change the needle if I change the size of the jet?  The kit didnt come with needles...
