Premium Roll-Over Valve Kits for Arctic Cat XF/7000 and Yamaha SR Viper

Arctic Cat XF/M7000/Yamaha SR Viper Roll Over Valve Kits


All XF7000/SR Viper Roll-Over Valve Kits are top of the line premium kits that come standard with our Electronic Roll-Over Valve Control Module or ROVCM!

Q, Why are Four Stroke Solutions LLC Viper/XF/M7000 Roll-Over Valve kits only available in the premium version? 

A, By using the variable voltage output from the ROVCM, we can control oil tank pressure during oil pump re-prime mode.

During cold weather durability testing on the Viper/XF/M7000, we found that the shut off valve requires a higher closing voltage then normal battery voltage alone. The higher closing voltage of approx 16.5 volts that the ROVCM provides, allows the shut off valve to close much more consistently over a wider range of riding conditions.

The ROVCM variable voltage output reduces valve cleaning intervals and often times eliminates the need to manually clean the shut off valve!

By using a variable voltage to control the shut off valve, the operating temperature of the solenoid coil inside the valve is reduced. This extends the life of the shut off valve for greater customer satisfaction!!

For a detailed description of about the ROVCM please see our high performance ROVCM page at

New ROVCM programming:

With the shut off valve mounted horizontally above the air/oil separator tank, we have developed new ROVCM programming to fully take advantage of this new mounting location. The ROVCMs are now programmed to initially close the shut off valve at 16.4 to 16.7 volts. This increases the valve closing strength by approximately 170% when compared to straight battery voltage and allows the shut off valve to be the strongest and fastest closing roll over valve built to date!

Battery voltage monitoring:

The ROVCM has a battery voltage/auto shut down feature. For example if the rider pulls his/her snowmobile in to the trailer at the end of the day and uses the tether cord to shut the machine down, but forgets to turn the key off. The ROVCM will start monitoring the sled's battery voltage after approximately two hours of "on time". If the battery voltage drops to the programmed level, the ROVCM will automatically switch off the Roll-Over Valve system to help prevent discharging the battery.

On Viper/XF/M7000 snowmobiles, if the rider uses the handle bar kill switch the shut the engine down but forgets to shut the key off, there will still be a 123 mili-amp drain on the battery. Because the ignition key is in the "on" position, one of the snowmobile's relays is still being energized but is not passing current. This is a normal condition and it's always best to turn off the engine using the key.

Note: because the gauge display is powered down the rider may not notice that he/she has left the ignition key in the "on" position.

A unique feature of the ROVCM battery voltage monitoring/auto shut down mode, is that it will also power down the snowmobile relay!

If the tether cord is pulled with the key left in the "on" position and the handle bar kill switch is pressed, the battery voltage monitoring/auto shut down feature will shut down both the Roll Over Valve system and the snowmobile relay to drop the battery draw to zero amps!

Engine oil pump re-priming mode:

The Quick Prime system is a fast, convenient way to re-prime the oil pump by simply pressing and holding a button!

If a XF7000 or a SR Viper snowmobile is laying of its side with engine still running, the oil pump can start to draw air due to the suction port in the oil tank being exposed to air. When this happens the low oil pressure switch may shut down the engine to help protect the engine. During this time the engine oil pump may have also lost its prime. When the rider gets the snowmobile back upright, he or she may find that the engine may not re-start or starts and shuts down within a few seconds due to no oil pressure. To re-prime the oil pump without a Roll-Over Valve requires removing the right side panel, removing the oil tank breather tube from the air box assembly and then manually plugging the breather tube while cranking the engine over. What this does is pressurize the oil tank, which in turn forces oil to the oil pump to re-prime it.

All XF/M7000/SR Viper Four Stroke Solutions LLC Roll-Over Valve kits are equipped with a ROVCM and we have developed programming specifically for the oil pump re-prime feature! During the re-prime modes the ROVCM commands the valve to close, which allows pressure to build in the oil tank and force engine oil to the engine oil pump for re-priming purposes.

The ROVCM uses pulse width modulation to regulate the air pressure inside the oil tank to safe levels. During Quick-prime mode the ROVCM regulates the air pressure to 8 to 8.5 psi.

Because the Quick Prime system uses air pressure to operate, the snowmobile does not necessarily have to be on level ground to function! The snowmobile only needs to be some what "rubber side down". This can be a real asset for mountain riders who may be stuck on the side of a hill or other mountain riding conditions and it is desirable to re-prime the oil pump as quickly as possible!  

Using the Quick-prime switch. 

To use the Quick-prime switch simply press and hold the Quick-prime switch down while starting the engine. Once the oil pressure light goes out on the gauge, release the Quick-prime switch. It's that simple, quick and easy to use !! Normally the oil pump will re-prime in about 2 seconds! You can also press the Quick-prime switch after the engine has started and notice that the oil pressure light is on. In this case it's best to push and hold the Quick-prime switch right away, so that the pump has time to re-prime before the low oil pressure switch shuts the engine down.

Compact valve design:

The best possible location to install the shut off valve on a XF7000/SR Viper is directly above the air/oil separator tank. In this location the shut off valve has the ability to help stop roll over oil leakage right at the point of exit. This helps prevent residual oil from collecting in the breather tube after a roll over event.

Another unique feature of the Four Stroke Solutions Viper/XF/M7000 Roll Over Valve kit, is that the shut off valve comes with the inlet hose already attached. The inlet hose is factory installed using a special high strength bonding agent and clamp. This improves hose retention in higher under hood temperature conditions sometimes found on Viper/XF/M7000 snowmobiles. Additionally with the inlet hose already factory installed, installation times are reduced and ease of installation is improved as well!  

Hood removal quick release connector:

Sometimes it's the simple things that can make a difference! Both the M1100T Roll-Over Valve kits and the XF/M7000/SR Viper Roll-Over Valve kits are equipped with a four pin weather proof connector. The connector is located near the factory hood harness connector and provides a quick disconnect point in the main ROV harness. This allows for easier removal of the hood as well as making the Roll Over Valve kit easier to install!

Genuine OEM Arctic Cat tether switches:

Just like our other Roll-Over Valve kits, the XF7000/SR Viper ROV kit comes standard with OEM Arctic Cat tether switches. The OEM Arctic Cat switch uses a brass center plunger, a rubber inner bellows seal and a cap center screw for years of reliable service.

Plug and Play installation:

The XF7000/SR Viper ROV kit is plug/play into the back of the ignition switch for easy installation. All Four Stroke Solutions Roll Over Valve kits include detailed installation instructions. Additionally we have detailed installation photos in our photo gallery pages as well!

Tether controlled:

Just like our other Roll-Over Valve kits, they are tether cord operated for simple operation!


Roll Over Valve kits are US patented under patent numbers 8,225,766 and 8,528,516.
