Thanks guys big help will put it in .I wonder owe many guys leave them out with
out knowing there even there? Found one guy to day at the speed shop and he
said, the oil filter bypass plug(that is what he called it) diverts oil from the pump and sends it through the filter so the bearings only receive filtered oil which is a must if you're using a modern oil filter.Anyone think he is right? still I will put it in to be on the safe side thanks guys big help. ktm
