I'm changing a bad fork seal on my 1999 GL1500 SE with a Roadsmith Ultimate trike kit which I believe has a 4' Roadsmith rake kit. Can anyone tell me the amount of fork oil I need in each tube? I don't know if the rake kit uses the same amount or more than Honda did on the OEM forks. Also, being a trike does it matter what oil weight I use? On my 1100 and 1200 I usually use ATF. Thanks.
