wadlesw96 Posted February 25, 2010 Report Posted February 25, 2010 Ok i have several questions. My mods are 19cc domes, k&n air filter, holes drilled in air box lid, trinity 2 in 1 carb intake with a keihn 36mm pwk carb, it is a range of 0-35 degrees and my elevation is 1,100 feet. I was running 93 with 40:1 ratio and my jetting is 190 main 52 pilot and i seized one of the pistons. Is jetting/fuel what caused this? I know my crank is good, please help me out. thanks Quote

GrMeyer Posted February 25, 2010 Report Posted February 25, 2010 Are u using oil that stays mixed in that cold of weather? Pull the head and look at the pistons if u haven't done so. Did u melt a piston or seized? There are a few things that could have happened. No oil in the fuel. Over heated. An air leak or just running lean. Quote
firebanshee Posted February 25, 2010 Report Posted February 25, 2010 You could have sucked the float bowl dry and leaned it out. Quote
