Hi, I'm doing and oil / filter change & screen cleaning on my 06 Ninja 250 trike. Can someone verify what order the bolt on plate, spring, filter and tin hat go on ? Something just does'nt look right the order in which it was as it dropped out. It came out in this order from the bottom up, Bolt on plate,spring, filter then sheet metal hat. Should'nt the spring been on the other side of the filter ? (first thing towards motor)
