Flushing forks... again.

[Jeff Tate]

I know I just posted the same question not long ago but I really need to know what everyone has used to flush out their forks when changing fluid. I was given a thimbs up on here to use kerosene, which is what i thought would be best. My local dealer says they use parts solvent and to stay away from kerosene. I hate to beat a dead horse but I really don't want my seals eaten up. I guess I just need some reassurance. I trust you guys more than I do the service departments at most shops. Thanks for letting bend your ear (or should I say monitor).

I used kerosene and let the forks stand inverted for a while to drain it out completely. I haven't had a problem with my fork seals in the year or two since I did this.

Kerosene is as gentle as it gets. Parts cleaners on the other hand can be harsh depending on which one. Diesel will work too.

[Jeff Tate]

Thank you guys soooo much! I was getting so many opinions... but no one was really sure. Thanks again.

[Billy Ricks]

Make sure you pump the suspension when you do it so the kerosene flushes everthing. Pump them upside down to empty the dirty kerosene. Do each fork leg 5 or 6 times to get them good and clean. You only need a little over a cup each flush.

Thanks alot. Will do.

I use automatic transmission fluid for the flush then run 2 flushes of fork oil

[jimcor]

I use WD-40 and then a cheapie 5W-whatever oil. Then the fork oil...which I need to change because the current batch is too heavy.

[Jeff Tate]

Yeah, a friend of mine suggested WD-40 also. But I wasn't sure.

[Billy Ricks]

If you want to pay the price for enough WD-40 no problem. Since it's mostly kerosene anyway it's much cheaper to use kerosene or diesel.

[jimcor]

Yep, kero or diesel is lots cheaper but, I don't use that much WD-40, the real flush is with the 5W motor oil. But WD-40 sure smells better than diesel!

I just got done flushing and refilling my forks. (I used kerosene) Worked great. Really got the old sludge out. So, with new fork springs and fluid and new shocks my scooter rides like new!!! And I didn't even have to throw stuff in the garage while doing it. The Gods smiled on me ( this time).
Thanks again to everyone for guiding me in the right direction on what to use.
