Hey fork pros: I'm in the middle of rebuilding a set of 2004 9sl forks for my fiance's Lightning. I have a 2003 Lightning manual and there is no info specific to the low model. First question: Type E fork oil(that's what is stock, right?)- I read conflicting info out there...is it 5w or 10w?? Second question: How much oil to put into the low" model forks? Standard calls for 8 oz or 4.57 inches from the top....can I use the same measurement from the top? Or is there different amounts and measurements out there that are "official" for the low models? Thanks in advance for your help! | ||

someone out there has some real knowledge of this for me... | ||

I heard a while back, that type E might be 10w but hopefully someone knows for sure. | ||
| Andymnelson |
yeah I've heard that too, but also that it's 5w!  | ||

Type E fork oil(that's what is stock, right?)- I read conflicting info out there...is it 5w or 10w?? I use Expert Motul 20W  How much oil to put into the low" model forks? I don't know either. But if the forks aren't leaking, measure how much comes out when you drain it. Or, measure like a dipstick before draining. | ||

Thanks Glitch. Doesn't really help me, as I would really like to know what the stock "base point" is with oil- for example: if I were to use a 20w (prob thicker than she will ever want), if type E is 5w, it's 4x the thickness, if Type E is 10w, it's only double! And your method would make sense...except one fork leaked and I drained both of them a while ago...doh! | ||

OK, with regards to oil weight. IIRC the stock oil is 5W the heavy is 10W and the heavy duty is 15W. When using H-D, I use the heavy or the heavy duty, just because I like a stiff front end. The 5W will work nicely. WRT the amount of oil, give a reputable dealership a call, and ask for someone in the service dept. | ||

When I replaced mine with 10W I had to back off the dampening quite a bit, to get the suspension back where I like it. This leads me to believe that the 5 weight or at least something lighter than 10 is a better choice. | ||

Kinda depends on the source of information. 10wt Motul went into mine, they feel great. | ||

Thanks for the info. Not the definitive answers I was hoping for on either question....but sort of progress in the right direction... |
