    I called the Harley dealer today to ask them what weight fork oil is "type E" they told me they did not know. well that's not very helpfull. so I put Amsoil 20 wt in which says it is the same as H-D type E . Does anybody know what weight H-D type is ?? Harley doesn't know. If I put a heavier weight in than stock what would be the difference??

    Thanks Glider, That might explain why when I turn around on a street say at 2-5mph with brakes slightly pressed the front endseems to hop on the tire grooves. I have been getting my 06 hritage ready for a 2700 road trip,one of the things I did, (as suggested by a H-D machanic) was to switch from the stock H-D type E to Amsoil 20wt. he said it would be the same, I guess not. would this fliud change cause this.?? thanks PJ

    Sure would! The heavier the oil the stiffer the front end is. 20 WT is similar to the SE racing fork oil and the 15 WT (SE heavy) I tried was very stiff, so I went back to the 10 WT, just right.

    Fork oil grades are not consistent between brands unfortunately.
