I've got a 93 580xltsp/sks, a real rocket ship!! I went .020 over several years ago and wanted to freshen it up w/rings and pistons this year. I dont have an oil pump and run Amsoil 100:1 synthetic pre-mix,(sled builder ran this way for 800mi. I ran another 2100mi,runs excellent around 9200rpm). Here is the problem, I know not to break it in w/ synth. and to run 1qt. of non-synth. oil per tank of gas, what would I mix the gas and other oil at to start with so it dosent burn down or sieze up during break in?? I should know but i dont think it was broke-in properly last time,ie. brown below the rings in about 1000mi.thanx!
