Here in the desert SW I don't think a heat shield is gonna do much for me. With ambient temps in the 110's airflow is the only thing that helps.
Need to figure out a ram air scoop from under headlight.

There is a natural air ram flowing through and above the radiator.
The shield splits this flow, hot below, ambient above.
The flow above the radiator can be improved by modifying the plastic frame inserts at the steer tube. There is a rats nest of wires there so I'm still thinking about it. The 1/4 gap along the front and sides of the glove box adds about 5+ square inches of intake area. At speed the front ram air is probably enough TBD. At slow speed the glove box gap should allow adequet intake TBD.

The new additional filter that is in the works is water repellant. No water slashing issue then.

The shield will block water spray from below but not from the front or top.

I'd like to buy the skin or filter cover so that I could accept delivery by 6/11. (hint hint)

Ok, I have initial settings that are going to be very close I think. I have an assortment of mains coming, but all I got in today was a 175 main and a 180 main, so that is what I started with. The needle is third clip from the top, and air screws out 2.5 turns. Stock 42 pilot.

IT RIPS!!! The intake howl with the glove box off is all business. It sounds like the intake on a Husaberg. I actually think I might be a bit rich on the very bottom with the air screws out 2.5. I will go back to 2.0 maybe after I ride it more. Drive-ability is very good too--no stutters, hesitations, RPM variations, and a nice rock steady idle.

As far as power increase, it is noticeable to say the least. It lights the rear Mefo up with full throttle in first. I was half wheelying and half burning out on asphalt just now.

I need more time to see what happens with fuel mileage, etc, but the initial performance results are very good. I am very pleased.

Dad2bike--I would recommend jetting from the top down--mains, then needle, then pilot/air screw. I saw where you are trying to jet the low end first and I think you will end up chasing your tail. Put the richer mains in, move your needle, and you won't need to have your air screws out so far and your bike will run great. It definitely does not need a richer pilot jet at least at my elevation.

Thanks to CPR for making this filter and thanks to CJ for giving us the hook up on a good deal. Finally, a proper foam dirt bike filter for our bikes.

Just wanted to mention that Chris at CPR is a great guy and he really knows about his customer service. just give him a call if you have any issues with your filter. He hooked me up with a new lower plate without me even asking. Buy with confidence he will back up his product

Thanks for your insights. I think we are around the same settings. I haven't got mains yet. Our needles are the same. The pilot difference just means I'm at 1 turn (45) while you are at 2.5 turns (42). I'm expecting to go to something like 170/175 mains for my area.
Has anybody tried sticking FCR mains in there to see how they work? I think I saw they are only .5mm longer.
Hmm. Washer?

Pre-filter & jetting

I can't wait till this comes available. Thanks to those working on it. It will be on the short list for my SE.

From the UK, but will this work for you?

That pushes the air into the radiator. Thanks for looking.

Jetting is available. You get the jets and put them in. I haven't figured out yet how a bunch of off the shelf ordinary jets magically becomes a "kit".

I think I got pretty darn close. I don't have a wide band sensor, but I can sure pull a spark plug and look at it.
