My opinion is that you should do your static break in indoors.If you have a garage or something slightly open a small window for ventilation,turn on the heating system so you wont freeze and finally start the break in.After you run 2-3 tanks static (the wheels dont touch the ground and the engine runs at idle till the tank empties then repeat process) you'll have to to the running break in. Then you can use what the boys have mentioned...rub the silicone tubes with preheated (in the oven at 40 degrees or with a hairdryer) aluminium paper. Start the engine indoors till it gets hot (hairdryer would also help) and while running outdours increase the idle a little bit so the engine keeps a higher temperature. I hope you'll not have any problems though.
