Excellent! Sorry about the instructions. We were pushing those out so fast back then we couldn't squeeze out the time to make them! We have a nice picture by picture one out for the RC8 and will change the current 950/990 typed instructions to pics as well.

Cheers

Jetting

Has anyone figured out the optimal jetting for the ktm 950, CPR intake, Akra cans with no plugs in?

If you can please post;

mains
pilot
airjet
float height
needle settings
fuel screw settings
other intake or exhaust mods
elevation
mpg

From what I have read running a filter-skin or prefilter does not cause a need to rejet from rottweiler without prefilter or filterskin, is this correct?

I am going to be installing and jetting mine so an idea of what seems to be working best for you all now would be great. Thanks!

I'm running all stock jetting with good results. I do have the remote mixture screws. Not quite sure where I have then at this time. I readjust when the local fuel change between winter & summer mix and back. I'm getting about 38-40 mpg. And that is with 16T front sprocket. I'm considering going backup to the 17T front since most all my riding is on pavement. That may take me back into the 45mpg area.

FMF single can
CPR with prefilter

I just did this.

06 950 Supermoto, sea level, or real close, anyway.

No filter skin.

Leo Vince SlipOns, no decibel killers.

Basically, just like Factory Pro recommended with their kit (I've got one).

Mains, 175/180

Pilots, 45

I've been told not to change the idle jet if I change the pilot to 45, so I didn't, it's stock.

Air Screws, 2 1/2 turns out.

Floats, 3 mm

Needles, Factory Pro Titanium, 3rd clip.

The filter is pretty lightly oiled, street use only, very little dust where I'm riding. Not sure if a load of oil will make it richer or not (less air flow), but I'm light on the oil.

Its runs pretty well. Very little to no choke when cold. Good throttle response. No lean surge on the freeway. Haven't had it on a dyno yet, no sniffer yet, I think when I do, it will tell the whole story.

It makes a pretty sweet noise, a little bit loud, but otherwise, the intake honk sounds good.

Mileage is low 30s, I'm pretty heavy on the throttle.

A little query to others with the CPR filter.

I've decided to fatten up my mains to get my power out of the top. I'm mostly a cruiser so stock jetting has worked well so far.
I've just been getting the itch in my wrist.

Have you guys found there is still the need to fatten up the rear main from the front?
I saw several posts in the past with guys running a single size main jet.
Edit- I'm presently 165/170 mains.
Edit- Looking at going to 170/175. Those are the jets I have already. Should I go bigger?

Thanks for you input.

I don't think so. I run 175 mains front and rear and both spark plugs look absolutely identical and perfect.
There are inmates here with a significant amount of experience (seat of the pants and dyno) tuning these bikes who claim the different main jet sizes from the factory is due to the stock airbox. Once you get rid of it you don't need different main jets at all.

That makes sense about the jets. I guess I will order in a couple of jets before doing this change. Thanks.

Just fitted CPR using head2wind jetting kit and rear jet one size larger than front on the main jet, that's on a 950SE mind so I'm sure there must be a reason as they seem to know their onions when it comes to jetting

Oh and makes a hell of a difference, so much better.

In process of fitting mine and awaiting jets.One thing is worrying me, does the filter base have to sit down over carb tops to squash fit the X rings, the holes in my base plate do not quite line up with carb tops though the stacks will go on. Has any body else had this or should I trim base to fit?

Hi mate, see my other thread had to trim the base plate to get it lined up. It needs trimming where the breathers are, couldn't work out if I'm meant to isolate them, with the original air box it vents through the snorkel so doesn't appear it needs filtering.

I'm not far from you happy to pop over. Jez.

Last weekend I changed from165/170 to 175/175 main jets. I also cut down the venturis. Today was the first chance to ride. OMG so much smoother. No little vibration at cruise. I think one cylinder was carrying more of the load. Now balanced power.
