I ran M1vt in my last bike. Switching this one over, too. I'm using Amsoil this go around in both the crank and primary. Still sticking with Redline for the tranny. With a K&N oil filter it all was damn expensive, though![:@]
I just popped $71.00 for 5 quarts of amsoil and a filter. I used to complain when I spent that on my car but the bike?? Oh well. Just overpriced though. $9.99 qt.
A neighbor up the road from me has owned numerous harleys. He told me that he only used the regular dino oil and rides the hell out of his bikes. No problems.
My old girlfriends dad use to change his oil with other peoples old oil and run it 5k to 8k in his chevy truck and put 250k on it before it took a ****. That don't mean i'm gonna try it.
