We now have ROV kits for the Viper/XF7000! All Viper/XF7000 ROV kits come standard with our ROVCM.
Also a new feature for the Viper/XF7000 kit is the oil pump re-prime mode!
The ROVCM adds features such as auto-shut down protection, oil pump re-prime mode and a much stronger/faster closing shut-off valve! For a detailed description of about the ROVCM please see our high performance ROVCM page at http://fourstrokesolutionsllc.webs.com/highperformancerovcm.com
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 15.6 to 15.7 volts. This increases the valve closing strength by approximately 150% 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!
Engine oil pump re-priming mode:
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 also have 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.
Because all XF7000/SR Viper Four Stroke Solutions LLC Roll-Over Valve kits are equipped with a ROVCM, 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 pressue to 8 to 8.5 psi. During method 2 (cranking re-prime mode) the ROVCM regulates the air pressure to approx 4 psi.
There are two ways to use the Roll-Over Valve to re-prime the oil pump.
Method 1, 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. 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.
Method 2, cranking re-prime mode.
To use the cranking oil pump re-prime feature, simply leave the tether cord pulled and crank the engine over (the engine does not start during cranking re-prime mode) for approx 30 seconds. The ROVCM will command the shut off valve to close and the LED will flash. After cranking the engine over for approx 30 seconds, re-install the tether cord and start the engine.
