Welcome to the 250R.net 2008 Ninja 250R DIY oil change thread.
We are going to do a step by step oil change to show you guys that are a little sceptical about doing it yourself that it really is a simple project.
But first to cover the intervals: You are fine to just go ahead and follow the manufacturers recomended intervals,However most people will tell you that is not enough.I am one of those people.
My change intervals are as follows: 1st 50mi.,2nd 200mi.,3rd 600mi.,4th 1200mi.,This is where I changed to full synthetic 5th 2000mi.
,6th 4000mi.,and will be every 2000mi. from here on out.This is due to the high RPM my bike spends its life at.(I average 75mph)
The tools needed:Bike stands if you have them,Oil filter (your preference),2 qts. oil (again your preference) (you will use 1.7 qts.),Rags, oil catch pan,Torque wrench, 17mm socket and rachet,small regular screwdriver (these other tools dont apply other than at 4000mi. or so intervals)8mm socket and rachet.
Pic. of the tools needed: - the torque wrench (I don't use one)
Ok now for the fun:
1st run your engine to normal operating temperature. 2nd put your bike on your stands. 3rd put your catch pan under the bike. 4th get your 17mm and rachet and remove the oil drain plug(be careful the oil is hot)
Pic of the filter housing, and the screen housing, and drain plug:
Here is a pic of the oil draining so that you know what plug it is.
5th loosen the filter housing and let it drain,then remove it (be careful the oil will be hot).
Pic of the filter housing draining:
6th disassemble the filter and housing over a bench so you dont loose any of the parts,clean all the parts.Use the small screwdriver to carefully remove both of the O-rings and inspect them(the purolator filter I use comes with new O-rings PN# ML16812).
Pic of the filter housing,and O-ring placement:
Wipe the O-rings clean (even new ones) and lube them with a thin layer of oil (some people use white grease),at this time lube the gaskets on the filter as well.
Pic. of the order of parts,they go together from right to left:
7th put the filter assembly together.
First put the bolt through the plate and then the spring goes on the bolt:
Now the washer goes on:
The filter,with this type it does not matter which side is first:
And the cap:
8th Put the filter assembly back in the housing on the bike and tighten it down to the torque spec 14.5ft. lbs. (or in my case good and snug)
