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??

Why not look in the self help area. it's in there.
The heavier oil will stiffen up the front end. I wouldn't go much over the 10 wt.

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
