Excellent oil for your V twin.
Not only do I use SPECTRO in my engine I also use it in transmission and Primary.
I have also used some of their other products and have always been satisfied with them.
Been using Spectro for YEARS !!!
The Best, as far as I’m concerned
Nuff Said !!!!
I especially like the “tremendous lubrication” feature 😀
I ride a Road King. Always have used HD oil. No problem…On the other hand, I also endorse Spectro. I owned a Yamaha vertical twin 650. It just did not want to shift very well when hot. I put Golden Spectro in it and the problem was gone.
I have to say the oil from the Motor Company wasn’t a hit in my CVO Dyna, so I switched to Amsoil and saw a massive improvement. I have had good results with Spectro in some of my other bikes, so I might give it a try.
