CPR filter install on my 950 Adventure

[dad2bike]

Here is the install for my CPR on the 950 Adventure.
I had already set up my bike so that I only have to remove the right tank for access and work on the carbs.
Edit- Forgot to note I got this kit from CJracer.

Tank removed ready to start sugery


Carbs pulled up out of the way.
The hardest part of this job was getting that freaking fuel line off the barbed T. That was one Mother of a task. I ended up cutting off the last 1 inch. With the carbs out of the box there was plenty of fuel line left for a proper connection.


Wife holding the carbs up to show all the room. Yes, I put rags back in the ports right after the pic.


Supplied X-rings in place


I removed the vent hose from the PCV valve and found a scrap piece to clamp on the end to hold the valve to the baseplate. The hose is pushed tight to the plate to provide air sealing.
The provided instructions make no mention of this hose. I just figured it out for myself.


Filter oiled and in place. I use Maxima FAB-1 oil. Really nasty stuff. Nuttin gets past that stuff.


You can see how clear the access is to the carbs now.
Note- The drain line from the air-box will be hiding down between the heads. Remember to pull it out. The carb vent line was stuck on the air-box and got put back on with a zip-tie to hold it in place.


Tank back on.


Glovebox installed.
It will be interesting to see the dust pattern on the filter and get an idea of where it really draws air from. I suspect the filter will draw from the front first and then as it gets dirty draw more and more from the back of the filter.
Available Airflow may change thru the cleaning cycles.


I haven't ridden the bike yet. It has all stock jetting at this time. Warmed up and adjusted the mixture screws. The bike feels really crisp and strong. I'll be sure to keep my self control until some proper jetting is found. Clearly it will want more fuel to go with all that air.

I have a nice 26 mile back road ride to/from work. Good place to see how this kit works out.

Great Info!

Thanks for the pics and post.

Wow... nice work! Looking forward to your first ride report.

Looks almost worth buying just to get rid of the crappy airbox, I hate the KTM airbox with a passion.

+1

And I need to dig into it: http://advrider.com/forums/showthread.php?t=786197

But its good at collecting leaking fuel and dumping it out the big drain tube!

Love it.

One question: is there an increase in intake noise now that the airbox is gone?

Sitting in the garage I could hear the intake at mid-high throttle. I'm headed to work in a few. That will be the maiden ride.
I'll post up about that later.

Yes, Your bike will have a distinct note to it now as you gas it past your buddies.

I cannot see this as a bad thing

[dad2bike]

First impressions with stock jetting.

Clearly I can hear the intakes. All the sound appears to push forward into the cockpit. That in turn comes right back at the rider. Nice sound though.

I pretty much cruise at 4K RPM's going to work. I could feel stumbling while at steady throttle with the throttle locked. Did some minor tweaking of mixture screws. It is feeling like starvation. It could be the CV's modulating.
I may go back to the 45 pilots and up the needle 1 position. It felt realt good while pulling WOT. Didn't pull long enough to run out of fuel. I'm expecting to need bigger mains as well. That is a whopping bunch more air intake.
I don't mind a bit lean since I'm looking for MPG's. Stock I was getting 40+ mpg.

[dad2bike]

For a 950 Has anybody done a measurement on the clearance from the top of the horns to the filter?
I'm considering dropping a plate on top the filter to cause it to draw from the sides. I'm thinking that might smooth out the CV operation as well. Hopefully tonight I can do that and up the needle from 2nd to 3rd position and Pilot from 42 to the 45 I have. I'm up to 3 turns out and still starving at cruise. I'll have to stick with the 155/160 mains for now. Hoping the local shop has a couple bigger mains sitting around.

How are you counting your needle position?

Typically, it's read from the bottom side being closest to the main jet. If following this convention, going from 2 to 3 will lean you out. IMO, try just the pilot and raising the float height to around 2.5mm before you touch the needle.

I read from the top down. The service manual does that as well. I've always counted from the top. That said, I will be raising the needle to fatten up the mid.
Funny thing. I'm going back to what jetting I was running with the Prefilter. Man It was FAT.

[dad2bike]

I changed the Pilots to 45 and put my needle back to the 3rd position (Center). IMS at 1 turn. Might go down to 3/4 in the future.
Feels much better and no sign of starving so far. I'm sure I'll be getting bigger mains in the future. I'm waiting to see what the dyno crew comes up with.
On those horns. I measured and they are only about 1/2 inch from the top of the cage. I'm thinking that may come back to haunt us 950's in the future.
I wonder what it would take to come up with shorter horns?
I'll see how this runs before looking at a cover of the top to force air in from the sides.

Also- I moved my intake boot claps such that I can now pull the carbs while leaving both tank on the bike. Only have to remove the seat, glovebox and airbox now. The carbs are accessible from the top now.

RC8 stacks are shorter, They are $20 or so the pair. Craig/CJdesigns has them
