Boss Noss Nitrous Oxide System

NoS takes a serious toll on an engine. I wouldn't use this unless I was running drags for money.

Now I know why you keep that relic around.

I agree.....not sure if I would put it on the maverick Rotax engine but it is a no-brainer on a 2-stroke snowmobile engine.......

I've never used NOS before so I know very little about them. This system is touting that it's a safe application but I don't want to try something like this without real feedback.

2 Strokes are super easy to rebuild. 4 Stroke Rotax not so much.

I can't see myself replacing it with anything newer as this thing has been bulletproof even with 190hp on pump gas and 270hp on the NOS.....but man is it hard to pull start this thing when it is below zero.....

They do make pretty simple systems. Mine is on a carbureted engine and it supplies it's own fuel as well. So if it is dialed in correctly, it is pretty reliable...... don't know much about their fuel injected systems though

I understand what you mean about reliable. That is why I kept my 2000 Skidoo MXZ700. I've never had anything go wrong on it and it has 7500 miles. It still has the original top end. Compression is down to 120 psi though now. Iv'e modded lightly but no major engine modifications. Hell, I installed electric start on it in 2005 and the battery is original. It wont die.

To run NOS on your Machine properly you will need to clutch for it and then your machine wont run as well when not on the Bottle. Kinda like propping a Boat. You either have good bottom end pull or good top speed but you cant have both.
If your serious about the Nitrous then I would recommend Nitrous Express kits they work awesome and there easy to deal with. Best Nozzle design around and My brother and I have used there stuff in the Past and ran multiple Mother Load bottles with no engine Failures at all. If you do it Right you will never hurt anything.

True but unless you are strictly using it for racing and need every ounce of speed, you would want to leave your clutching setup alone since you ride more without the NOS than you do with.......mine would hit full shift out in about 1 1/2 seconds and just pull until you let off the button.....

No it doesn't. Anyone that knows performance engines knows that Nitrous Oxide, if used properly, is safer and easier to setup than a turbo'd or supercharged engine. I'd be more worried about clutch and belts. Nitrous Oxide, at such a low level as this kit, is less engine stress than a turbo with no extra heat to control. Ideally you want to be able to pull timing a few degrees when activated, but that would require a module to interface with the ECM. With the higher compression and (apparently) aggressive cam timing of the maverick, I would be hesitant to try this system without the ability to retard timing with NOS active.

NO2 simply increases volumetric efficiency through a more complete combustion.

Ok has anybody tried it on a maverick yet. I see they have been used on the commander without a problem. I searched the Internet to ask the boss nitrous manufacturer but can't find them.

I would just love to try this out but don't want to blow the thing up.

Any help would be appreciated.

I'm still curious too. I have yet to hear or read 1 Maverick owner using NOS.

Never used it on a sxs but had it on a few cars. I agree with these guys that as long as you do your homework and set it up right you should have no problems. If you cant pull timing with it i would def run high octane and go a step or two colder on your spark plugs and gap it accordingly. Id say a 30 shot would be just fine, maybe even a 50hp shot but id start small and jet up and check plugs as you go.keep an eye on bottle pressure , and fuel pressure. Both will affect your jetting.

ZEX? ZEX? Polaris RZR Nitrous System

This would work fine on a mav too, might want to call them and varify jetting

BOSS NOSS doesn't have any fuel pressure, the fuel is siphoned in. I've never used one, but a customer brought a bike in with it. Was gonna tune it, but he wants to pick it up, and we don't have time. He says he's gonna come back later on, so I can tune it. Looks like a good idea, albeit unique, compared to others.

I have a boss noss system on one of my trail Mavericks, stock motor with cams and ecm reflash. I spray it with 15hp per hole and it loves it.
