I am getting ready to change out my fork oil but the hold up is "What weight to use" and "What brand to use"? The MoCo has type "E" which is about a 10 wt. and SE at 15 wt. and SE Heavy at 20 wt. There is also Belray at 10 and 15 wt. Do you use just one weight or mix to make your own blend?
I had some 20w left over and mixed it 50/50 with HD 15w. Seems to be good so far. About 500 miles on it. When the temps warm up if I'm not happy I will go to all 20w.
i'm using the screamin eagle heavy. it isn't harsh riding at all, and i no longer have that squishy feeling in the front end, and the biggest bonus for me was my bike doesn't dive when coming to a stop. it's a great improvement over stock.
Why does it say not for street use on the back of SE Heavy Fork Oil. Scary? I jsut put it in mine this weekend because the HD desk jockey said that is all they use. He said they have a heavier one but do not use it. After looking here I think what he gave me is the heaviest.
