So let your machine warm up, even if you’ve just stopped for lunch during your ride. A cold seize occurs when the heat of compression expands the piston faster than the cylinder causing the piston to become stuck in the tight-fitting hole. All metal expands with heat and contracts with cold. If you do not allow the machine to warm up, the result can be a cold seize. Letting it warm up allows the coolant to sufficiently circulate through the engine and literally for the engine to warm up-again creating optimum running conditions. Some say wait till 120 F before laying in the hammer. Upon cold start, ensure that your machine warms up to at least 100 F. Synthetic oils burn cleaner, keeping the entire machine running strong. Some feel the old style petroleum-based oils actually lubricate better but tend to gum up injectors and exhaust valves. Some even suggest adding a bit of oil into the gas tank prior to each ride, as a little extra insurance that you are providing enough lubrication for your machine. A high-quality synthetic oil ensures continuity in viscosity, thus creating a more stable lubrication system. Oil adds lubrication and facilitates optimum bearing performance. It’s important to use only high-quality oil for your snowmobile. Spending many seasons working with Polaris’s Liberty engine, the techniques Gulbrandsen uses have been tried, tested and true.
Parkland Motorsports is one of the most respected snowmobile modification shops around. The Power Commander is not adjustable on the fly, which lessens the amount of tinkering on the fly. The Power Commander has a variety of maps available-depending upon which manufacturer you are dealing with. If you don’t, then a Power Commander would be the way to go,” said Chris Gulbrandsen, owner of Parkland Motorsports in Stony Plain, Alberta. “If you know what you are doing, the BoonDocker box is an excellent choice for a fuel controller.
So take the time to learn the system and speak with the manufacturer and your local dealer to ensure complete understanding before you program a controller, such as the BoonDocker control box. This most certainly isn’t a learn-as-you-go scenario, as the result could be a catastrophic failure for your engine. It is an absolute must to know exactly what you are doing when programming a fuel controller. Understand how your fuel controller works
Same thing: a seized engine will occur.Ģ.

Individuals who have fuel controllers and do not know how to properly operate them can find themselves in a sticky situation-if, in fact, they run their sled too lean. The pistons and possibly the cylinders will need to be replaced. The piston’s aluminum composition will melt and become stuck to the cylinder wall, causing the engine to seize. If there is insufficient fuel running through the motor, this will cause the motor to run hotter-so hot, in fact, that it could burn down.
High-performance machines with aftermarket additions causing a higher compression-such as a turbo, big bores and aftermarket piston kits-sometimes need a higher octane of fuel. Most stock machines call for a 91-octane non-ethanol fuel to maintain the integrity of that motor. Here are some things to consider as a machine owner to ensure the longevity of your engine.Ī high-quality fuel is important. Nothing can be more disheartening to a rider than engine failure-it's costly and sometimes season stopping.
