I run Amsoil in my crankcase but as I was having my bike painted by a painter and a wrench I had him do it for me as i was leaving on a trip. In any case I had a reduced effort clutch installed (01 FLHR) and had him put Lucas in the primary and tranny. It now shifts a whole lot easier with less clang. And I sure do love the reduced effort clutch, something I have been wanting to do for a long time....

 

I was recently at a Rally and the Lucas tent was set up next to us..I had the guy change out all 3 fluids on 2 bikes while we were there.. Unknown to my wife, she rode her bike the following morning about 30 miles came back and asked me if I did anything to her bike because she said it shifts better..I just told her that I had the fluid changed and she said it seems to run better..So there you go..
