Oh yeah, one thing I forgot to mention that may also be helping my economy out is I have the Holtzman ATTAC (automatic temperature and elevation compensator) installed. It claims in the literature that it increases fuel economy by always keeping you at the optimum jetting. Maybe it does? PB
Happy Holidays Everyone :!:
Just got back from a 7 day visit with the family and had a great
time trying out those K&N's (300 klm) what a blast and the sound is awsome. This thing rocks but i'm going to try the HH's for more top end which i'm not getting with the dalton's. Yes :!: the fuel milage has increased by about 5klm per gal from my previous setup, which i was amazed because of the tendancy to pin the throttle more for the sound it makes. :twisted: :twisted: All i can say is wow :!: :!:
As i said before best bang for the buck.....
The burble is still there but very slight as the engine warms up
it does'nt seem so noticable im thinking it sounds worse because
the air box muffeled it before. I'm more than happy. :wink: :wink:

Makes perfect sense to me. You don't have to give it as much throttle to get up to trail speeds. If you do really get into the throttle you have to back off quicker because you usually run out of room much quicker :shock:

BR, I fail to understand what part of my last post is BS. :roll:
If the testimonies of all these people that have replied to this query don't make you want to believe them, then why would mine? I just reply with intelligent reasons why it is possible for the mileage to be affected very little or not at all. I operate a very busy shop and frankly don't have the time to go out and test for fuel mileage. That is why we have all been gracious to share everything that we do know about this modification.
So tell us what your findings were...

Is this good enough? I speak from past experiences when referring to people driving differently than before once the performance is improved. TB had an increase in mileage even with riding harder than before!
This is the type of info that we all need. Someone else with a different clutch setup or track setup or even more aggressive riding style may see different results. This is TB's true-to-life experiences. Hope these help.

Supertuner, I would LOVE to see what affect a change in needle position has on fuel flow (and of course torque and h. p.) in the midrange on the dyno if you happen to run a sled in the near future.
A set of needles from a FZ1000 would be interesting to try but that's whole other subject.
Thank you for all the wonderful support you have given us on this forum. I must say I haven't seen interest like this from ANY other shop. Yes, there have been Cameo appearances but not a sustained presence. Now if I could just convince you that 160's work for elevation :lol:

I agree PB.
The other thing I have allways wanted to do is install R1 carbs on the RX1.
I have two sets of them, I figured out how to get them on, just never had an chance to get with someone with a cnc mill to build the adapters.
I feel the downdraft carbs may be a asset in themself let alone being bigger. (40mm vs 37mm)
Too many ideas, not enough time :wink:

PB...I will be doing an exhaust comparison probably within one weeks time. I will adjust the needles to various clip positions and report the findings. If you could send me the FZ1000 needles to test during this time, I will be happy to try them. If 160 main jets make you happy...I am happy too! 
MXZ900...although I haven't tried full downdraft carburetors off of a R1, I have tried Lectron carbs. (I distribute Lectrons) They showed no appreciable gains that make the investment worth it. They did however make the power quicker, but like I said...not enough to make it worth it. I do believe that with porting the Trons would work though. They were 40mm Lectrons.
There is a realistic gain to be had with going back to the downdraft induction like the cylinder head was designed for...would look cool as hell with a hood scoop like Warren Johnson or Greg Anderson has too!

Supertuner, thanks for trying the needle positions. I think all of us will benefit from the results.
As far as the alternative needles go. Which ones do you recommend? I don't think a dynojet kit is really warranted but will you need more than needles (like a nozzle) to test different needles? Are the 99 FZ1000 best or maybe R-1 carbs from before 02? I don't have a clue? Are you a Dynojet dealer? I have asked those guys Dynojet) to do some testing for us but they want nothing to do with it they are motorcycles only. I see them as a Swiss watch maker as digital watches were coming on the scene. The four stroke watercraft use these carbs too. They may find out too late that they should have played. PB

Just got back from jackman,and average milage w/filter and mostly wfo runs was 13-14 mpg and gps 115 mph on snow/ice oh ya dreemeter 131
oh ya dreemeter 131YamahaRx-Warrior

How were the trails in jackman going up this weekend to bring some stuff into the house and ride. I also want to get a set of filters are they hard to install the jets.

Trails for the most part sucked,but if you hunted you could ride,we got 250 miles on sat,and sun,but sat was warm and i have never seen such wash outs,i blew out my rear shock and hit a rock hard enough to bend my left spindle housing,dont know yet if spindle is bent too,but the housing was $202.00 w/tax not cheap,happy trails. Oh yea did i mention the ticket from local warden for failure to stop at road crossing,coming off small pole line on dead end road just before you come into this guys back yard next to rail road,had a brain fart was being pushed by friends rev plus one snow dust was bad to,oh well my fault should of come to complete stop,i guess no warnings this year,i was the example,he said he could of giving both of us one,but i was the lead sled so he thought i should be the guiny pig lol oh well lake was awsome,fish shacks and sleds all over it.

Yes I am a Dynojet dealer and they have no future plans for offering jet kits for snowmobiles. We work a great deal with the Power Commander units from Dynojet for mapping Fuel Injected bikes. Even with the advent of Fuel Injected snowmobiles, they have no intertest and have completely turned the FI program for snowmobiles over to another company who is developing a Power Commander for FI sleds.
As far as what needles to try...I'm afraid that I don't know as I thought you already knew what needle would fit so we could try them. My suggestion would be to obtain both sets and I will try them both. I will contact them as well and see if they will send me just the needles from their jet kit.

Supertuner, I had a PM from someone who said to use the FZ1000 needles. I thought I saved it but when I checked marked the messages to save I think I actually erased the ones I wanted to keep.
I'll do some home work too. I have a good feeling about this. PB

UPDATE:
Just contacted Dynojet to order the needles from 6 of their jet kits to try. They will not sell me just needles from their jet kits.
However, the fellow that answered the phone patched me through to "the mans" voice mail. I told him that I was trying to develop a jet kit for a snowmobile (which they have no interest in) and that if they would be willing to send me some needles to try on the dyno, the result if we have good results would be me placing an order for hundreds of needles.
He will not be back from the holidays until after the first of the year. We will see what he says when he returns my telephone call.
