I'm replacing the front strut carts. and the manual calls for 125cc of shock oil. the parts stores and dealer both gave me a funny look and told me I'm crazy. So, what do I do now?

 

go to your local motorcycle shop that still works on harley's or someone who has worked as an auto mech for a very long time (30 +years) they will know what you are talking about if they don't have it they usually know where to get it

While you are there get a few diff weights so you can experiment my car has about a 50/50 mix of 10/40 and 30w (didnt have enough of either sitting around)its a little stiffer than most people would like but great on a crooked road
