KTM 950/990 CPR Foam Air filter Kits at CJ Designs

[cjracer]

990 and 950 Filters are in stock, ready to ship. Tune ECU cables are here too as well as SAS plates and oil kits.

Most Pre-orders have shipped. Some orders are waiting to be shipped with other back-ordered items as discussed.

If you think your filter should have shipped, please email me with your invoice number for a check-up.

A few orders got mixed up because payment was sent before I sent out an invoice. Those should be straightened out now and shipped today.

Sorry for any confusion from my end.


HOT OFF THE PRESSES!!!

NEW Foam filter outer cover in testing stages.


More info and pricing to follow.

A Water Resistant Cover option is in the works too.

Just getting back with my first Longer trip test with this setup.

1400 miles, lot of water in mud holes. Never had any issues with splashes on the SE.


I ran the CPR "RC8" Filter, Custom chopped trumpets and an off the shelf Filter Skin. This ran untouched during the trip, only pulled the seat off once at 400 miles to make sure all looked well. My jetting might not be perfect, but if felt real nice.

No surging, or dips in power that my butt could feel. I was getting about 30-35 MPG cruising with 16/45 gearing on road and 25-30 off road having Fun!


This is very close to what I have found with the UNI Prefilter setup running leaner jetting and the stock box compared to the CPR running richer jetting. I won't have time to get it on the dyno anytime soon though to do final tweaks. It will stay as is until I have more time.

Everyone that test road the 950 SE this last week commented on how smooth and powerful it was.

-LC8 950 Custom Trumpets-
I have more OEM 950 trumpets on the way. Once I get them here and have them modified, I will post more info in the Vendors thread for those that want them.

Finally got it installed along with a Bazzaz Z-fi & Z-AFM....the instructions weren't clear, for me any way...
Do this look like the proper routing for the crankcase breather hose

Took me a minute to figure it out too. You need to separate the crankcase vent hose at the metal valve. The top piece (that you have on top of the mounting plate) will not be used anymore. The metal one way valve goes in through the bottom of the mounting plate and fits perfectly in the countersunk hole. When it is done correctly, the metal valve will be sticking up through the mounting plate, and you are done.

For the crankcase hose to fit correctly, I had to trim a couple of inches (maybe less I don't remember) off the bottom side of the crancase hose. This allowed the valve to fit in the mounting plate perfectly. Trim a little bit at a time so you get it just right and do not cut off too much.

Ok...I wasn't sure because step 11 on the CPR site reads:

11.Attach the upper “Post check valve” part of the crankcase breather hose to the check valve installed into the plate and routed facing into the forward velocity stack.
You may use the extra spring clip for this.

Seems like without the hose would be a better/cleaner install...

The rubber hose piece provides the sealing and holds the valve in place. Be sure to point the clamp in towards the horn. The hose nipple just fits next to the filter edge.

Why put a hose clamp on top of the mounting plate? Installed properly, the breather hose can't go anywhere.

I just went to the CPR site for info. Didn't have it when I did my install.
Now I see how it was to be installed. Whoops.
From the site:



I guess I installed wrong. I put the filter on the outside with nipple up thru the hole. Then small piece of hose & clamp holing it in place. Functionally the same. Just not as clean. I will rework it.


I was one of the early installs. Not much for install docs back then.

CPR just replied to my email with the following:

That’s certainly close enough. The idea is to shorten the hose with cutters so that it points down into the velocity stacks and consumes the puked oil.
Make sure the check valve is pointed the correct way or your motor will blow the rubber gasket at the valve cover. (Someone already did this)

Let us know if we can be of any further assistance.

Interesting. Those intructions have changed since I got mine. Mine came with zero instructions. I will be leaving mine as is. Rigging up the hose to the carb intake looks like an afterthought to me. It's not necessary anyway.

[dad2bike]

How do you get the over 1" OD hose into the top of the horn with only 1/2" of clearance between the top of the horn to the filter?

Mine is just the valve pointing up. Uhh.
Besides I don't want that oil going into my motor.
I'm begining to think it would be better to just put the little K&N on the hose and call it good.

...which was my first thought too, but then you would not even need to run it through the mounting plate, and would have to rig something up to plug the hole for the vent hose.

I have a couple tanks of gas through mine and no oil through the breather, so I am not going to worry about it.

I've had no issues with my installation either. Just loads of bugs stuck to the filter.

[adiablolex]

I didn't get instructions with mine either so I just routed it facing outwards toward the filter.
I was getting a bit of oil on my air jets since I have to replace the balancer seal so thought better to do that until I change the seal
