Ive got it all pulled back into shape and have been riding it on my test track (my drive way) with a small aux fuel cell to mess with the last few things before I hang the left tank on it and start taking it around the block/I-5 for a real world test. As soon as I get that done, the 950 is getting torn down to get some new and interesting bits bolted into it thanks to a few SDs that met early bike death...

I guess the 178-188 jets that Head2Wind references must be custom drilled? Just saying that because I have not been able to find any that big except in steps of five--175,180, 185.

My bike runs good at 175/180, and I have also tried 170/175, and have those main jets in while I wait for the removeable foam covers to become available. The hot dry air this time of the year actually allows for leaner jetting too, which seems backward but its not.

All my air jets are stock which is probably not optimal, but otherwise I stayed with the stock pilots and moved the needle clip to third from the top. Idle is good, but it has a bit (not bad but not perfect) of a flat spot at low rpms (3-4k) when you roll the throttle on hard. Above 4K it pulls clean and strong.

any noticable torque / power improvements? If so, at low/mid/high rmp's? I still wonder about the slides not operating in a vacuum anymore as there is nearly no resistance with these kit's. Do you still have responce when you whack the trothle open?

Yes, it is a noticeable difference to me. Pulls harder mid to top, and throttle response is as good as stock if not better.

update

I posted my jetting trial in one of these threads, so I thought to give an update on how this holds up in the dust.
We recently finished the Roaming Rally http://advrider.com/forums/showthread.php?t=750329

Most of the trails were extremely dusty and to tell you the truth I was a bit apprehensive on the filter's performance without the cover skin as I haven't ordered one yet. We also encountered a bit of rain and a couple (or six) water crossings 2-3' deep.
I intentionally didnt even check it other than removing the saddle for a quick visual and did not notice ANY loss of performance as the days went by and the filter got filthier.

Here's a pic of the dust on the bike, sorry about the shakie



a couple of the filter bathed in the finest silty sand Ontario and Quebec have to offer




this thing loves bugs!



the moment of truth:





clean as a whistle, not a spec of anything in the protected area, carb throats sparkling clean

Very pleased so far with this setup, the bike feels like it has more torque, better mid and high, but I'm still messing around with my jetting as I have open pipes and would like to try the jetting with a bit of restriction.

Thanks again Chris for an awesome product, I'll be ordering the filter skins soon

Diablo out

Bit late but Factory Pro make half steps

is that the slides struggling to open with low vacuum? that's what i like about the 950, its pretty good right off idle.

I don't think so. It still pulls good off idle. Just a tiny bit of a flat spot and only when you try to make it do it. Riding off road under normal throttle openings and operation, it is better than the old air box. Whack the throttle open at 4K in first on the street and you will flip if the tire hooks up.

I don't think the vacuum signal is a factor at all. Maybe an expert like Head2Wind could chime in if this is really an issue or not.

I have found that the low end jetting--air screws and pilots were not really affected too much by this air box. Needle either. These carbs are so forgiving of jetting that it is hard to tell without the right equipment like a wide band and a dyno. The exceptions are the main jets. It needs FAT main jets, no question.

Work has slowed down some so I will have some time to do a map. I took off the custom exhaust and put the stock one on with FMF mufflers. This won't be a bad ass smooth map as that would be proprietary but a good base map for you guys. I'll make sure your not too lean. Also will probably try the Akra map just to report back the A/F ratios.

This will be for
CPR filter
RC8 velocity stacks
aftermarket mufflers
secondary butterflies active

Are you seeing any MPG difference with the new setup?

Hi all,

I have now had a bit of time on my 03 Adventure with the air kit I got off Two Moto Kiwis. Its a CPR Rottweiler. It came with needles and jets. 178 & 180 mains, 45 and 55 jets. Needles are on middle clip. They are from Adventure Machines.
It runs real nice everywhere except if the wind is gusty at freeway speeds. Then I am getting the feeling of slight fuel starvation. Its only slight but I can feel it. If there is no wind or a tail wind its fine.

Could this be anything to do with the carb breather hoses? Or possibly float bowl height. This I measured at 3.5mm
Carbs are sync`d and TPS was set right. Breather hoses terminate under carbs in the V of the motor.

It took did nearly 14 kpl doing a quick hills ride.
Anyone like to share their views?

Cheers.
