I have foolishly been changing oil and not changing the oil filter every time so I want to start doing so.

What size oil filter should I be using ? Is it something I can get at the local wal-mart or atv shop (perhaps a Honda powerhouse).I checked my manual it didn't tell me what size I need to buy

Secondly I live in Canada so it is cold. I would like change the oil filter soon. What proper steps should I take for changing the oil filter in the cold of winter ? Run the machine for a few min first ?

lastly, I just put new oil in the machine before I filled her up and put in stabil for the winter. Do I have to drain the oil to do an oil filter change ?


Thanks Guys !

You can get them at Bikebandit or your local Honda motorcycle dealer, not sure about Honda Powerhouse.

You will lose a little bit of oil when you pull the cover off so you may need to add some more oil after you do the filter. If you do it cold you are likely to lose less oil than if you run the machine first. I would change the filter and then run the machine to get oil circulated up there and to make sure you still have enough oil in the machine.

Here is the Bikebandit part number and price:

ELEMENT, OIL FILTER ,A 2A 581090 (214811-001) 0-99 $6.50

And Service Honda Part number and price:

ELEMENT, OIL FILTER 15410-KF0-315 (replaces 15410-KF0-305) 001 $4.62

I heard those filters fit tons of different applications so they should be at any bike / small engine shop.

K and N is a KN112
and highflow is called HF112

There is a big 'o' ring and a small one and they usually stick to the cover, so don't lose them.

Also remember the way it came apart....cover...filter...spring or whatever order.. I forget but it would be virtually INSTANT engine head meltdown.

I usually tip the trike up so it doesn't leak too much at all when pulling the cover.

A little oil on the o rings and it should go back together and not leak.
I had one that had never been changed and there was residual factory sealant around the cover, kinda like a super thin bit of shellac so you may get away with a TINY bit of sealant but the 'o' rings should do it.

If you're worried about oil pressure, pull the plug or plug wire so it spins up without firing and then your pressure should be up with a primed filter galley.

So you say KN112, I called one of the small engine shops in the area and they were giving me something with a 113 ending...what does this number mean ?

The Honda shop in my area is closed today...jerks. I have head that an incorrect installation will fry your bike I am going to take the utmost care to see how it all went in so I can put the new one back in correctly. i think I have some oil sitting around from a change awhile back, I will just put some dabs of that from my finger onto the O-rings

KN113 is the K&N part number. It sounds like the shop has the correct one. http://www.knfilters.com/search/applications.aspx?Prod=KN-113

If you get the oem filter from the dealer it says on it which side faces out so you don't mess it up

WHOA! so maybe the k&N 112 number I have is wrong?

It came from a honda shop. Yikes!! I have at least 3 machines running with the 112 in there.

Yeah, some filters say 'this side out' and some do not.
One side of the filter is just metal and the other side has a square cut rubber ring glued to it.

^%$%#@# now I gotta double check that 112#

Thanks

OK

The KN 113 is listed for the honda 250es and sx...same engine
the KN112 is also listed for both 250es and sx but has an outside diameter of 50mm and the 113 has an outside diameter of 52mm.

Why do they do this to us?

Just to see if we're paying attention?

Not sure but that is weird. Only 2mm difference. I bet you can't tell them apart looking at them

I am no machinist but 2mm can make a huge difference...in some cases. From listening to drjoe171 I think the 2mm in this case ruins nothing ^_^

Fram, enco - there are tons of them out there. I've got them at AutoZone or other Auto parts stores............They seem fine.

However, you cannot go wrong with OEM and the 2 orings from Service Honda. There minimum shipping is 9.99$ but think about gas and time; No one does...... I place an order and it takes 1 week to be at my door. No fear of cheaper filters etc.........

2MM or .080 can mean the difference between oil bypassing or oil going where it's suppose to..............

If you cross reference the number to a WIX filter you can get them at almost any auto parts store and usually the WIX filters have came with O-rings.

fyi you will want to have someone help you balance the machine on 2 wheels when you put the filter in, it will make life a lot easier. if the machine is sitting flat gravity will try to spit everything out as you're trying to put the cover on otherwise. i run a fram in mine, from fleet-farm. don't know the part # offhand.

I guess it's good to shake things up but all 3 of my local shops carry the 112 K&N for the 250es and sx. and they list both 112 &113 for the 250

112 is, Say 2mm smaller OD than the 113 but if you think of the old canister type filters, the outside can diameter that the filter element fits into can't really matter.

It's the id and critical pressure that runs into and thru the filter and continues happily pressurized on it way to irreplaceable engine parts,
at least that's what I'm hoping.
Then again, that kinda of extra clearance in the wrong place, like rod to crank journal, or cam, could be a disaster.

If K&N lists both the 112 and 113 for the 250, you think it would be ok.

Man, ignorance is so much more blissful, but thanks for the heads up.*

I found some K&N 113 Filters for $6.00 a piece at the local bike shop ! Looks like I am stocking up after work.

I'd be curious to see how much mud and sand is in the lemon. Hopefully there is none.

I did the oil filter change today...it was pretty gruesome. I think the picture will tell you everything you need to know. I also had to clean the spring it was so covered in what looked like hard mud and scum. Lemon ran great after i changed the filter with a KN113. I did some cheating today too.....I bought new kendra back tires and the rims were causing a bead leak....soooo since i do not have the tools to take a tire off and put it back on , I just emptied the air and put silicon around the rim where it was leaking (showed to me by soap and water) so I hope to have stopped that pesky leak !!

either way I am super happy to have a clean oil filter in the bike ! from now on I will change my oil filter any time I change my oil !

That's to bad in what you found in the oil filter. Hopefully the cam journals aren't to bad along with the rest of the engine that was lacking oil pressure.

Well it seemed to run fine when I started to today....I mean i am only a novice so I do not have the ear that you would. but the machine worked and there were not funny sounds ! any further suggestions ?

PM me on your computer, did the last E-mail work, do you want Remote desktop done ?

Holy crap, my filters never look like that........

Thats some serious sludge/crap. Hope that cam journals are AOK.

Nope, have to take gas tank off, unbolt the valve cover, take cam chain off, remove cam and inspect / measure, all at top dead center.
