I drained out the old fluid, installed new Progressive fork springs and new ATF in the forks. They sqeak when bouncing the forks up and down now. The old springs didn't do this. Never had this problem when changing springs on other bikes before. Any thoughts?
 
I always use BEL-RAY fork oil for all standard and cartridge forks consistent damping performance, special frictional properties reduce stiction,extends seal life. The atf has a friction additive not the cause of the squeak run them they might stop squeaking after they breakin. Some people run the atf but designed for transmisions not front forks. Your call on that one. Did you put the closer wound coils to the tree end or the slider ?
 
racerDave, when i replaced my springs the recommended oil was a 7 or 10 wt and with springs out and legs compressed filled to within 5.5" from the top.

Maybe you just don't have enough oil.

Read this it might help.

I don't honestly remember which way I put the springs in, but I think I put the close wound end down like the Progressive instruction suggest. There should be plenty of oil. I used Yam's volume specs, 169cc,which should make the level a little high, as Progressive says their springs displace more oil, and there also would have been some old oils lurking in the tubes..
 
hi,,, you can put progressive fork springs in either way,, it does state so on their box /leaflet in box they come with .... regards oldbiker
 
Well that was a some what of a trick question since it has been said many times that direction makes no differance. Well that depends on witch direction the progression begins from the tree or the leg. I run mine with the tighter wound springs at the trees. Since springs are springs and do make noise I would rather have the loosely wound coils making spring noises in the slider and not the tree. I can't say for sure its less logic ? The tight wound coils the last used before coil bind might produce less shock at the bars you make the call. :thumbsup:
 
Just following up on this thread. I've run into the same squeaky scenario.
Progressive springs, new fork oil, new seals, new dust boots.
@racerdave did your squeaks go away?
