I did a complete oil change on the new bike (new to me) It has 9000 miles on it and was dealer serviced 1000 miles ago but I like to know whats in it and when. So I bought the oil (syn amsoil) and changed the engine and then put amsoil syn gear in the tranny and went to the primary. I put my first qt in and went to get another. (book calls for 1.40 qts ) well i thought I had another but didnt. HMMMM going riding tomorrow what to do ???? Well i had conventional 20 w 50 rev tech. so I added what i needed in the primary. Went riding the next day , couple humdred miles. Ran great no noise no pull no slip no heavey clunks NOTHING ! worked great. I am just wondering if ok to leave it there or should i change it out? winter is apon us soon in the northeast USA and she will be going to bed soon. So do i need to do this or is it fine the way it is ? Thx
