I see many posts for Spectro tranny and primary oil, was wondering if anyone uses Spectro Golden in crankcase? I hear it is great oil and just wanted some thoughts from those who use it.
Much thanks,
Curt J

 

I just bought 4 quarts of their full syn. I have not changed it yet.

 

I just put their new fully synthetic (GL-5) 75w140 gear oil in my transmission today. I only had time to ride it for about 10 miles before I had to come back home so it will be another ride or two before I can post results.

Thanks fidget, i was really wondering about Spectro crankcase oils not tranny oil, but thanks anyway.

My bets,

Just changed to Spectro Full syn. Engine is quieter than with HD SYN3. Also I don't get that loud ticking sound I got with the Mobil 1 V-Twin
I will keep using the spectro.
