I'm seeing people also use hydraulic jack oil for shock absorbers. Any one here use anything besides fork oil? This page shows there are a lot of similarities between fork oil and jack oil, and they say that fork oil is basically the same as SAE 10w, but is this true? The page looks like an old archived forum post. mgaguru.com/mgtech/suspensn/fs110.htm |

The page looks like an old archived forum post. mgaguru.com/mgtech/suspensn/fs110.htmI'm also interested in whether substitution fluids work. I threw the idea out there hoping some the knowledgable guys would chime in. |

I was waiting for a good day so I could be outside, today is "good" its like 45 out now, the highest temp it's been in months! I'm actually working on the tach right now, just making some wires with spade terminals to make hooking it up and removing it easier in the long run. I don't have enough space on my dash so I am just going to bolt it onto the plastic near the mirror stem. The positive wires on the tach splice directly into the red wire on the ignition switch? Wasn't really sure about the positive power source when we first talked about it. The oil for the shocks are really confusing. My friend who works at a hardware store says they sell al sorts of oils, pnuematic oils, motor oils, lubrication oils, but no fork or hydraulic oils. It is hydraulic oil that I need right? Or is it called fork oil? |

It is basically transmission fluid except that the viscosity of fork oil is either better controlled (maybe) or simply listed (probably) whereas tranny fluid is not. Can't remember which version of transmission fluid - I think the normal GM version. Other hydraulic oils would probably be too thick |

I haven't gotten into the ignition switch before this really, not sure if that is always feeding power or if it only feeds while the engine is on, that's what I am confused about. Because if it feeds power all the time then I would need a different spot or a switch? Found out there's a shop near one of my friends a town over that sells and services motorcycles and isn't listed on google maps, got the # from my friend and called, they say they have all sorts of fork oils, do I need a lightweight oil or a heavy oil? |

you need a volt-ohm meter (or light) to know. Just check. Yes, there are different weights of fork oil, depending on how firm you want your ride and how your specific forks / scooter weight are designed. MAYBE (?) a scooter shop will know this - or just go middle of the road. In my 1000 pound motorcycle (only one i have messed around with fork oil) I ended up using a tranny fluid (which was too light; not enough shock absorption) and then added small amounts of  weight gear oil to get it where i liked it. |

My scooter is pretty light, I can pick it up myself but I guess I am prtty strong? I'd say the scoot itself is about 200-300 pounds? The weight limit on the scoot is 550ish? I forget what it says. |

My 150cc is about 220 pounds ---- very light on the front end (classic style). Has a pair of whimpy shocks on the front instead of even forks.

I drained the old oil, measured it up 50mL each shock. The oil in the shocks looked black. I cleaned them out with brake cleaner, then rinsed them out with some fork oil (yes, I know, redundant) hoping it would grab the remaining cleaner on the way back out, which it did. Then filled both shocks up with a little over 50mL 20w fork oil. Pumped them a bit before putting the springs back in to release the air from the bottom.
Went for a ride, the shocks feel brand new now. Feels smooth on the front end, pretty much no vibration in the handlebars now, and takes potholes like a pro now.

That's great , its nice to see something actually go right for you . |
