i did an oil change on my brother 2005 yfz450 and then on his 2007 350 Raptor (with the same drain pan) and put it all back together. But after i emptied my drain pan of oil i found this filter screen thing that has a spring on it that iam assuming belong to one of the quads (iam assuming the raptor)....but where does it go???? any help is appreciated!

this is it:

its been a long time since i changed the oil on a raptor/warrior 350 .... i think it goes where the oil drain bolt goes ... when you you took the bolt out to drain the oil that would of came out also .... if i remember right there is a picture of it in the manual on how it goes in

its from the 350, on the oil drain bolt.

it is another screen for the oil.. it goes with the white pice up and the spring aginst the drian pluge... if you dont put it in another pice will fall out into the bottom of the motor
