CRF250 air filter change

[kjjz28]

About to change out the air filter on my CRF and in looking through the shop manual, it says I need to remove the subframe to replace the air filter...is this true? It looks like if I turn the cage/filter at an angle, it will come out or am I subjecting the filter to possible damage?

I read a previous post about not using "No-Toil" on UNI filters but is it O.K to use it on Twin Air or Moose Filters? What do filters cost these days?

Thanks folks!

Definitely no need to remove the sub frame.
I can't answer your other questions as I use a K&N.

I just used a stock filter (I liked them best), and no-toil was fine on it. Can't speak to the twin-air or moose. But I've not heard anything either. I have heard about the twin air problems though.

I run moose filters with No-Toil. I think moose filters run around $20-25, but it's been a while since I've bought any. Recently I bought the pre-oiled No-Toil filters, I think they're right around $10. Not sure how many uses you can get out of one, I think I've cleaned mine three times now.

I do enjoy those no-toil pre-oiled filters a bunch. Cleaning isn't bad, but if I can swing it, I like to just buy those instead.

Are you sure it says you need to remove the sub frame for the air filter or the air box? There is no access anywhere other than the top that doesn't even make sense.

I got the filter out without removing the subframe...the diagram in the manual makes it look like you have to remove it to get to the airfilter but it really is to get to the entire airbox.

BTW...went to two dealers yesterday and another motorcycle parts store and none of them had either a Honda filter, No-Toil or Twin Air. One of the dealers did have a Maxima pre-oiled "Ready Filter" that appears to be marketed as a single use filter. I needed one to ride with my son today so I went ahead and bought the filter. Anyone have experience with these? Are they truly single use or can they be cleaned/re-oiled and used again until I can get another filter ordered? Thanks!

I use Ready filters and reuse them as well. They can be reused until which time the material starts to degrades. I find it is around 4-6x depending on how delicate you are when washing them out. They are fantastic to just have a spare in the tool box. Not as thick and durable as Uni or Twin Air but I change mine every ride or 2.

I have use stock, twin air and moose on my crf250's with no problems. Moose are the least expensive and durable as any i have used. They are smaller than the stockers too. You can get it preoiled for $1 more. I pay about $15 with my discount. So for a spare to go with the stocker or replacements I buy Moose. Never messed with subframe just twist the cage a little to get it in and out of the subframe.

ABout the K and N, Is it worth the price. ANy noticeable performance gain. thanks, j

I use a twin air dual stage filter with the twin air filter cage. It allows more air into your carb and is easier to use than the restrictive stock cage you use in your crf. Notoil oil and cleaner a must.
