I"m a huge Silkolene fan. I use it in my race bikes (dirt, 2 and 4 stroke) and my 93 900ss. I am going to pro 4 after I break in my new motor. Motorcycle oil is very specific. It not only lubricates the pistons but also the tranny. Gear mash breaks down oil at an incredibly fast rate so automobile oils like Mobil 1 do not protect against gear mash and will break down more quickly than m/c specific oil.
