Fluids

I dont want to start a big deal. This is the first time I am going to change my gearbox and primary fluids.
What weights and type fluids go in these units.
Not asking brands or synthetics or not, just what is the proper type fluids

Mike,
You can start by going to the work shop manual for your bike. If you don't have one then the top of the forum here will get you to a downloadable one here. technical-information-how-post-photos-t2357.html
Andover Norton has a newsletter that you can ask to send it to you.
This month covers all the grades of oils for the commando. http://www.nortonmotors.de/ANIL/News.htm
