    I'll bite..... what filters are we discussing paper, foam, cloth???? Before or after washing all the crud off from the filter cover? Under the influence? Method of cleaning?

    I've always thought that changing the oil in my engine was bad for my bike.... I'm not sure I get this thread:norton

    For those of you who aren't aware the theory behind not cleaning an air filter is that the dirt it has collected acts to further restrict the openings in the filter allowing less debris into the motor, by cleaning the filter you are not only removing the additional filtering agents but also enlarging the openings in the filter during the cleaning process. I rub cheap $7 air filters from rocky mountain and replace them every two years or after any deep water submersions.

    As far as not changing oil I don't understand what that poster is trying to say. I change my oil every 2,000 miles, And use a new filter only after every 2nd change for the same reasons stated as above.

    For me nothing to discuss, every oil change at between 5000 - 7500 we wash and very anally re oil the air filter and pre cleaners x 3, wash the stainless steel oil filter out very carefully as well as mesh screens

    By filling the holes up in the airfilter makes it run richer, use more fuel and will lead to bore washing ... good luck to those who choose this route.

    I agree, if you don't clean/replace your air filter it will become more and more restrictive and eventually prevent the engine from starting, therefore causing less wear on the engine.

    Most air filters are designed to flow 2-3 times of what the carb can flow. Granted a clogged filter will cause power loss, but I don't think the op is saying that it should never be replaced, just that they shouldn't be cleaned

    It's called over servicing and some amount of dirt/dust will find a way into the engine every time. It's all about making sure it needs to be changed in the first place. A filter minder would be a great addition to a motorcycle, I'm going to install one on my Goldwing so I can just change the filter when the gauge says it's restricted.

    I have one on my truck. That's a great idea. Do they make a motorcycle specific one or are you going to mod your ow,. I would be very interested in pics or a write up :lurk

    I don't think that's correct, his statement...

    "Cleaning/replacing air filter is actually bad for your engine"

    Clearly states cleaned and/or replaced.

    He needs to come back and 'splain himself or we'll start jumping to conclusions.:wink:

    FWIW,,, the OP did post this in OC knowing full well (assumption on my part) these bikes have paper OEM filters. So is he saying just changing an OEM filter is bad for your engine. Surely there is no residual dirt/grit in a new filter element.

    Awwww come on,,,, you're not giving up that easy are you?? :lol3

    Besides I think you guys are onto something with the filter minder! Although you do still need to change/clean the filter at some point.

    Making up my own kit, it's horrible to just get to the filter on a Goldwing, that's why I'm doing a filter minder on this bike. It's pretty simple, just tap a fitting into the airbox between the filter and intake tract, mount the minder someplace safe and run some tubing to it.

    It's technically bad for an engine to change the filter, some amount of dust will get into the engine. We call it 'dusting' an engine in the HD truck field. That's why there is a primary and secondary filter on a truck, dusting can take hundreds of thousands of miles off an engines life.

    I put this one on my BMW, I can change/check the outer filter all I want and the inner filter will protect the engine from dusting.
