Has anyone got any tips on getting a Yamaha VK 540 started below -25? I have a 2006 VK 540 with 1000 kms (great engine compression). I am 198 lbs and can hardly get it to turn over with the pull cord at colder temps with the spark plugs out! With plugs in there is no chance of turning it over let alone making it fire. I hear this is a great bush machine but I need some cold starting tips; otherwise its back to the snowshoes!
