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)
I will be running the cover as soon as I can buy it
Very cool CJ. How much and when can I get it.
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.
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.
Ah....it's the early hours in the uk and I've properply noobed one out there! Thanks for being so polite about it!
It's a wonder how we ever tuned our bikes back in the days before electronics huh.
The CPR filters worked well for the MX 1000. Mike finished 2nd overall without a filter change! Out chase truck driver rode the bike out of MX from Cabo for a total of 2200 miles and the filter was still working well! Big thanks to CPR. Mike and I both got dusted out by Terrible Herbst and Robbie Gordon
Our jetting is perfect, we got 92- 100 miles per tank at race pace and some of was dry lake bed and deep sand. I've never been in 6th gear that long on dirt. Sustained speeds of 80-100+ for hours. Head2wind and CJ helped us out big time!
Thanks great news!!!
Really. Can't wait to see pictures. And congrats on the race.
Got out for 100 mile ride this morning and although the bike ran great, my fuel mileage was terrible, so I will try smaller mains, and see what that does.
Edit: Actually my fuel mileage was really good, for some reason no fuel was drawn from the right hand tank (yes I had the fuel tap (s) all open). I must of pinched a line. I'll pull the tank and check it all out. I have had the tanks on and off a dozen times and never have done this before.
I actually found some mud, in a not so dry wash. The outside of the bike was pretty muddy, but there was none at all on on the filter. It looks like the tanks really shield the filter well, and that is one thing I was curious about. I rode by myself today, so conditions were pretty much dust free, so no test on that part yet.
I worked with Team MacPherson Chevrolet running a Trophy Truck and Class 4 for 3 years back in the 90's.
Watching a Trophy Truck scamper over the whoops at 100+ MPH while passing motorcycles cured me of any desire to be on a bike on any course at the same time as those guys.
Congrats on the excellent results.
Herbst passed me just outside El Arco in the rocky stretch and Robby caught
me on a sand road on the way to San Ignatio. I was going 90-100 and he went by like I was sitting still. He went wide, so it was a nice pass. The experience was easier than I thought honestly
The Sand whoops in San Filepe sucked
Stobie used to keep that bike So Clean!
