I just bought a 2002 zr440 sno pro with a blown motor, i have rebuilt it and is all back togther. Im wondering what type of fuel to run in it and where do i set my timing dial? When i took the pistons out the look like it was running hot. No damage was done to the cylinders except some aluminum on the walls. I replaced the pistons and had the cylinders re done and just trying to avoid this from happeining again.Any help would be appreciated.[thumb]
