For those of you that are using the Spectre filters for your bottlefed air mod, are you sure we're supposed to oil them? I know it sounds dumb since they're cotton fibre filters, but when I bought mine, I looked at the package, and nowhere on it was there a mention of oiling the filter or if the filter came pre-oiled and ready for use. If you look at the larger Power-Adder filters, their package states "Pre-Oiled and Ready for Use" and there are instructions to clean and oil them every 6 months. Even the cleaner/oiling kit by Spectre does not mention the small profile cone filters on their list of uses. It says "Use this Air Filter Recharge Kit on any Spectre PowerAdder High Performance Cotton Fibre Air Filter. PowerAdder air filters are washable and reuseable and add horsepower to your engine!" The pics on the box only show the P4 and P5 PowerAdders and some round element filters. Nowhere does it mention the short cone filters. I oiled my filter before I installed it, but I can't help but wonder since neither the oil kit nor the filter package itself says any single thing about needing oil or being rechargeable. Same thing with the crankcase breather filters. They're cotton fibre, but do not mention needing oil or being able to clean/reuse them. I oiled my breather filters too though. For those not sure... these are the filters I'm referring to.

Air is flowing out of the Crankcase through that Filter... There is a pretty good chance it is being oiled for you.

Why do you say that? I thought putting a breather on the hose alleviated that problem. Besides, I'm talking about the larger filters, and whether or not they are supposed to be oiled or if they can be cleaned and re-used.

I would not let there bad package designs and documentation stop you from oiling them.
They need it and should get it.

On the big ones, yes they are pre-oiled but I would oil them anyway as they seem kind of dry.... They are intended to be cleaned and re-used, and spectre has a cleaner/oiler kit you can get at Auto Zone or Pep boyz.

On the small ones, the reason I say that is that there is postive pressure in the crankcase that vents through those lines. For emission reasons they route those lines into your air intake so that you will burn off any oil vapor in the engine. Putting a filter on there and letting it breathe out into the open air is no big deal but there is inevitably going to be oil vapor/gasses coming through that filter...

Ride your bike hard one day with that setup then take a wiff of the small filter when you come to a stop.

I bought that oil kit.. That's part of the reason for this post, since it only mentions using it on the PowerAdder line, which are the bigger ones. It doesn't mention anything about the small cone filters. I would personally email Spectre about it, but their website is useless for support. Their entire Support section is empty, stating more will be added soon. No link to contact them is anywhere on their site.

I clean and oil the large filters... And I don't worry about the small ones, at least not yet.
Oil vapor is blowing out of those so they eventually will need cleaned. When I finally have to clean them I will put a very light coating of oil on them.

Never tried Spectre's support... but I hate to hear that... nothing worse then a company with whom you cannot communicate!  :verymad:

Those filters are a "Wetted Gauze" type filter and are meant to be oiled, EVEN the little ones as when you shut the bike down, air goes back in the tube, so in that case, no filter, dirty air entering crankcase.

Those filters CAN be over oiled. They are not a very good filter for keeping dirt out when oiled to the manufacturers recommendation, but a little extra oil will help aid in filtering although it defeats the purpose of the filter for increased flow.

If you send me the exact dimensions of the filter, including air horn diameter and both ends of the taper, I can see if there is a Nano-Fiber filter available for it. The Nano-Fiber filters flow as good as the wetted gauze and filter up to 50 times better.

I know lots who do not run a filter on the crankcase vent, if you are not overfilled and don't have much blow by (bad rings) it is not going to shoot much of anything out and I never have seen a motor hurt by it sucking anything in it and even if that were a worry there is usually a screen under the area the breather enters the motor that is wetted with oil to stop that. some people have run a small aluminum or plastic catch can at the end of the hose leaving it vented of course but not filtered. that will catch any drippings you might have.

You've never seen a "sanded" engine ? I have seen many over the years. The whole idea is to keep the engine internals as clean as possible. Catching any dirt before it enters the engine is key rather than handling it once it is in there. Once dirt enters an engine, it IS causing damage, no matter how minute, before it can be removed. I guess I just look at it from the stand of creating Longevity of Equipment.

That is why I haven't retired my work van with 339,000 very hard miles on it yet and it has never had any internal engine work. Not even injectors as I use a concentrated fuel additive to help keep them clean and working properly. Use the same treatment on my bike too.

This could easily be remedied by a PCV valve like is used on cars... if someone were worried about it...
The large air filter and small one we are using on the Crank Case vent look to be the same construction, So if the little one cant keep dust/dirt out then we have bigger problems to worry about with the large filter that is dumping tons of air into the intake.

Is it the best filter on the market?? Maybe not... Who knows, but I believe it is adequately performing its intended function, which is to keep dust and dirt particles out of my motor.

Wetted Gauze Filters have been around for moons and their popularity grew with the Foreign Car generation because of the underhood aesthetics of chrome tubes and various fiber colors available. Those same filters such as the Spectres that folks are using for big air kits for cycles require oiling. Someone mentioned about over-oiling! Depending how the filter is mounted any excess oil will settle to the bottom edge of the filter and can be wiped off with a paper towel. Spectre sells their own brand of filter oil but you can use K&N etc. without adversely impacting the filters ability to do its job. Stock Car Racers who run on clay and dirt tracks use K&N etc and spray their filters with Dextron II automatic transmission oil/fluid! It's pink in color and does the same job as filter oils. If anyone is going to have the potential for "foreign particle" induction into their motor, those forks are at the top of the list when it comes to protecting their investments! Bottom line...."if it is Gauze", oil it!

i was useing the small crome spectre air filter and i just change to these spectre air filter`s http://www.powerflowracing.com/spectre-prtdetail.asp?PD=716 , they are alot bigger and cost about 4.00 more then the crome one`s. plus my 9 is red . norman
Actually, there doesn't appear to be any more surface area exposed for filtering compared to the small cones on my bike. Since the small cones also have filtering surface area in the center, their actual surface area is pretty much the same as one like yours that is closed in the center. If you had gotten the PowerAdder filter, you would have more surface area since they are opened in the center.

This is the one I'm talking about. It's the PowerAdder P4. Personally, I think it would look better than the one you got on your bike since it's got the chrome too. http://www.powerflowracing.com/spectre-prtdetail.asp?PD=671

I believe the Edelbrock Pro Flo 1000 Series is a Heart shaped filter and looks great on the 109.

Someone from this forum sent me the pics of their bike with those units ob and it really looked good sitting right between the V of the Jugs.

Many people over the years have used ATF and just regular oil for gauze type and foam filters. The problem there lies in that the Intended product for gauze and foam filters has a Tackifier which make the oil sticky and collects dirt. This tackifier will also allow over oiling of the filter that is not as noticeable.

I have had many people throw out their $50+ K&N's when I suggested to them to take a very clean white T-Shirt, spray a little Pledge on it and wipe downstream of the filter to check for dirt.

After running a K&N on our Late Model Dirt car and noticing the dirt in the throat of the carb, we went to a paper filter with a foam wrap. Problem fixed and we went to a track Championship that year.

Even K&N's liturature says that the filter does better as it gets dirtier. I can add a couple HP by changing oil so sanding an engine for a couple HP is not worth it to me.

I don't think Oil Doc was indicating the small breather filters are inadequate... he was referring to running no filtration at all on the breather hose as someone else mentioned. He also indicated that the small breather filters require oil just as the large cones do to filter adequately.
