You may have over oiled the new one resulting in less air flow. That is the only thing I can think of - did the power loss show up right after installing the Piper Cross?

 

Yes I think I might have as well. Power loss showed up right after installation.

What do you suggest at this point? Replace it with a stock filter?

 

If that is the issue, take it out and clean it and re oil it, taking care to not over do it. Is it a foam filter (i.e. you need to squeeze the excess oil out)? I used No Toil on my KLR and always found I could squeeze a lot out after I oiled it. Don't wring it, just repeated squeezing. Good luck and good on you for making this journey! A lifetime of learning and adventure!

 

I agree, take it out, clean it well, and re-oil. It's easy to over do it, you wouldn't be the first.

 

I called NoToil last night; and they also thought I had over oiled it. Having followed the directions on saturating it; I thought I was AOK.

I will be taking it out and cleaning it when I get to Campeche (Yucatan coast). I think I found a connection through a motorcycle club that has a garage and has offered to host me for a few days.

I also ordered a OEM paper filter as a backup and am having that shipped to me in city I'll cross just as I reach Belize. That way if I never get the performance out of the Pipercross that I'd like, I can always switch back.

It turns out ordering a part in the USA and having it shipped to Mexico is both faster and cheaper than waiting for a Mexican motorcycle shop to get a part. Kind of fascinating really... but I think that's due to them just not carrying parts for bigger bikes as they don't see a bunch of them.

 

Over Oiled

You over oiled the filter, no doubt. Been there, done that. You don't need much, especially using No Toil as its super tacky. Just enough to get it wet, then squeeze it (don't wring it) until you get a drop or so of oil to drip. Again, it doesn't take much; much less than you think.

Ended up cleaning and re-oiling it. I think I'm experiencing a MPG drop with this type of filter set up. I'm anxious to try the OEM filter that I'm having shipped to me and see if there's a difference.

For those of you with Pipercross filters; have you noticed a loss of fuel economy?

 

Hi folks:

Writing to you from the town of Palenque Mexico.

I did a lot of research and decided to go with a Pipercross cleanable air filter. I thought, given how annoying it is to find any parts in Mexico that I would make my life a *bit* easier by finding a re-usable air filter that I can use and clean.

I also bought a No Toil Air filter cleaner kit as well. I then installed it correctly (the finer foam - (red side) down) with the included rim grease.

I swapped out the air filter a few hundred miles ago and threw the stock filter away... because the Pipercross one would be *so much better* right?

So now I'm riding and I feel a noticeable loss in power and torque. I would put the stock filter back in but I threw it away.

My thoughts are:
1) The simplest solution is almost always right......

Hi Good Brother. I used a couple of foam style, you oil it air filters, on other bikes some years ago and always found them to be more work, not less.

Personally I went the BMC pre-oiled, free flow air filter route. Great flow and performance, rated for well over 100,000 miles of use, and all you do is drop it in like a stock air filter,

K&N also has one for our bike that also comes pre-oiled but I find the BMC to be higher quality,

If you are interested in going this route, I can help you out.

Email me Directly at b.layton@svracingparts.com I think you will find the BMC route a lot easier,

Enjoy the ride, and best regards,
Blair

 

No loss in MPG or performance, but no gain either! I took the snorkel off, but I think after 20K miles I'm finally tired of the noise so I will be putting it back on.

No reason why there should be. The job of the throttles is to restrict air flow to the engine except at wide open throttle. A bit more restriction through an air filter is meaningless. If (big if) a clean stock-type air filter actually does provide a significant restriction of air flow at wide open throttle and high rpms, and if (big if) a so-called high performance aftermarket air filter truly has less restriction (only possible if clean), then the aftermarket filter has this wide open throttle, high rpm benefit. At lower rpms the engine doesn't pump enough air to matter. At any point except wide open throttle the throttles are doing their job of restricting air flow. A re-cleanable air filter is a good idea in a few circumstances, and it is always a messy bother.

I think there are six options for strom air filters---
---Suzuki stock air filter
---HiFlo stock-type
---K&N oiled cotton gauze
---BMC oiled cotton gauze
---Pipercross oiled foam
------and the DIY filter where the stock element is cut away from the frame and a small car air filter element is glued in.
