Ridden with a number of guys running NOS. Once it's set up it seems very reliable but the set up is what gets guys frustrated. Even when set up at a dealer it takes a bit of tweeking in the mountains.
I think it one of the best bangs for the buck from what I've seen.

Powderchowder I put nos on my 4 stroke last year and love it. The new Bossnoss system from Boss is what I am using, and it is completely regulated so and you add add noss it increases your fuel, reducing or elimiating melt downs. I went with a 40hp shot it works great, my Rpm goes up about 400-500rpms and stays there until I let off. With the regulated system you can hold the button down until the bottle is empty if you want!! I find with my sled when you let off it bogs from a second or two, from it try to burnoff the extra fuel that just went into the cards. I was told by Bossnoss if you go any higher then 50hp you have to start mixing with race fuel. Good luck and let me know what you go with.

NosRX1, how was the set up once installed, our buddy runs the same system on his RT1000 and it took a lot of tweeking to get it working right. What was your experience?

Sledbunny I found it easy to dial in, on the fuel regulator valve I leaned it out 1/8 of a turn until it worked great from when I first started I turned it in about 1 1/2 turns from factory recomended setting. And now its nothing but a smooth running with lots of power when I am on the button!! what made me think of leaning it out was after I got off the button it would almost bog to the point of putting you over the handle bars, so just leaned it out until I had lots of power and little to no bog.

NosRX1--- where did you get your Boss kit from and what is the price? Did you install yourself?

I have an 05 RX Mtn that could use a little extra kick.

 

[NosRX1]

Accually My wife bought it for me last year for my birthday(Yeah you can say it what a girl!!) She got it from Karst in Casper when we were living down there. I believe it cost around 870.00 USD. I just had deal put it in for me there was alittle more to it then a stock set up, I am running pods with the K&N jet and spring kit so I felt it better to have the deal do it.

 

[Culvert]

I also have the K&N's with single pipe. what kind of jetting are you running in the Mtns? 6-9000'
I run 165 MJ's here at 2000' but dropped to 160 and it ran boggy in McBride. gurggly on the trail ride up and then at a certain height above cabins it would just load up and go nowhere.
would you mind passing me your set-up for higher elev. Clutching, jetting?

Thanks, Culvert

 

[Slamnek]

i would also like to know more about nos.

 

[NosRX1]

I am running 150s for jetting, the clutching is stock it seems to work fine, I may play around with the clutching this year see if I can get more out it. This last year I was just happy with the way it was running! so never bothered changing the clutches.

 

[Culvert]

Thanks, Nos

I will be dropping my jets down for sure next time around. If you get a chance to take a look let me know what you have for clutching.
I have 8BU-10 13.3T 13.9H with W-S-W primary and 54-42 helix with silver spring at 80*.
I pull 10500-10700 at 2000' and when we went to 6-9000' it was pulling 10000 but dropping to 9000, way to much lost in RPM. But I hope to get the jetting first than play with clutches.
