I know this might sound stupid but this is my first quad a 02 P650. Where is the back spark plug do I need to remove any plastic? Also I found the drain plug but where is the fill plug on the front and rear diff's and is there a fuel fliter that might need to be changed.

 

Do a search for posts on this topic -- ive seen this question here many times before..

 

CRAW... I highly recommend a service manual... this is a fairly complex machine, & there are a lot of mainenance & service items you can actually do better than your dealer can ( knowing the way you ride, & your time frame )... the torque specs are in there, & it is not uncommon, to twist off CVT belt cover bolts, etc. with out the torque specs...
