I acquired this bike about 15 years ago. It´s been in my garage the whole time. I recently got my motorcyle license and have brought this guy out of retirement. Have enjoyed every minute of it. I picked up a manual and could not find any real specifics regarding the type of oil to put in. I put regular 30wt motor oil in it as a test. It works fine but I am not sure this is the correct stuff. Does someone have a recommendation or should I just get some Honda motorcycle oil?
