    That is the wrong seal. There are both Kawasaki and Honda motorcycles that had 39mm ID fork seals, that is what I use. I believe the Honda seal is for something like an '85-'86 VF750 and the other is the '85-'86ish XL350R. They are the same OD as the Husky with 1mm smaller ID, this helps with a tighter seal, there is more stiction at first but once they break in they are fine.

    Quick question... I noticed that when I installed the tubes into the lower that it would bind about 6 inches from the bottom of the lower. Should the tube easily go to the bottom? This happened even before I put the seals in.

    Also how much does each fork need after a complete rebuild?

    have you tightened the lower bolts up on the damper before pushing the tubes to the bottom. ifso the damper rod can be misaligned and bind on the inside of the tube. always bottom the tube before doing up the damper rod bolt under the forks.
    if you don't have the damper rods in, you have the European enduro champion...bengt phorks...

    They bind before I even have the damper installed. Just putting the tubes in the lowers they stop about 6 inches from the bottom. When assembled, I dont think the tubes will ever get that low but was just concerned. They are together and seem to be ok. Thanks

    i guess stock would be so just the cap is showing or maybe an 1/8th inch of chrome..
    did you get the binding taken care of? there should be none, really..

    I think so. I might have to drain an recenter the damper on one fork that has a slight squeak when I compress completely.

    if your riding tight woods type single line, 1st 2nd 3rd gear trails and tracks, pull the forks up half an inch above the top clamp and soften the rear springs a couple of slots. the bike will turn in much nicer. if your looking at top gear stuff in the sand or open country run the fork caps level or at the tubes/ cap thread line level with the top clamp to gain some straight line stability. stiffen the rear springs a couple of slots as well.

    that's pretty well spot on. if you centre the damper rod and have smooth tube action (said the bishop to the barmaid...) you can bang the springs and caps on to hold the damper rod for that final tweak. ive found that if the paint on the recess in the bottom of the fork slider is chipped or not fully cleaned out, they can weep a few drops if your not riding much.

    Help on feedback - I just got a set to try , the smaller size than 40 mm Hey so tight , i mean real tight.

    Do they loosen up. of far by hand not moving good. John I seen your forks work on the 430 were they this
    product. ?? Mine came from Moose.

    Also checking on the SKF seals - the non friction or reduced friction. the Marzoccki model may fit expensive

    Well I got some so going to try them the 39 that is.

    But also downloaded the SKF phone app on seals
    they seem to be a bit thiner , but all in all seem to be new option to try for huskies. But $63 dollars a set for
    these is a lot. Must be the low friction material. They are a 40mm 52 x 8 in size. Ordering is deceiving as cost is for one fork only 31 a
    side
