Flushing forks

Postby KYWinger » Tue Apr 05, 2011 6:27 pm



:?: I have the forks off; the aluminun is all polished and I have the caps off and the springs out.
Question---since the fork oil is 3 to 7 years old, what should I flush the tubes with prior to putting in the correct amount of ATF? (and what is the correct amount for an '83 Aspy?)
I'm thinking it can't be too powerful since I'm not replacing the non-leaky seals.....
Thnaks in advance, guys. My bike wouldn't get done without this site..... :D

If you are not going to disassemble the forks the whole way down then I would just refill with ATF, pump the sliders up and down a few times and dump the fluid out the bottom. Repeat a couple of times and refill with the proper amount (sorry couldnt find the correct amount for you).This way you dont have to worry about solvents eating your seals,cant say they wont leak just likely to be your best bet with good results IMO.

:o :o Well now I've done it....in trying to get the allen bolt out of the bottom of the fork slider, I've managed to round it out (28 years of never being taken out)
Any suggestions on how how to get it out? Kinda stuck at this point. Not sure if it really has to come out to completely drain the fork or not...what say you all???
Thanks!

One way to get them apart now is to drill the head off of the bolt then get the fork apart and use Vise Grips to unscrew the stem. Here's a picture of what that bolt looks like.
