I'm in the process of changing fork seals on my 93K1100RS,, I took out the left fork spring and the tight coils were on the bottom , but in my Clymer Manual,Page 609 it looks like they are on the top. Does it make any difference whether the tighter coil end is on the top or bottom , : Thanks ::Hilton

Makes a minor difference on fork oil volume but not something you'd probably ever notice.

FYI: Factory installed the tight coils at the top.

I noticed when reading up on this repair that some guys were complaining about the small fill hole for replacing the fork oil and the time it took to go in,,,When I refilled mine I cleaned the fork tube off pulled the upper tube out as far as possible and put a wrap of duct tape around it at the dust cap so it wouldn't move ,, I turned my trusty Black and Decker workmate on it's end and blocked it off of the ground to accommodate the ABS sensor and clamped the fork in it vertically,, with the top cap left off and the top baffle out I measured the oil in a Pyrex measuring cup and poured it right in the top of the tube,,, the oil peculated through the one baffle pretty easily, I replaced the cap and was done fairly quickly,,I used an adjustable pipe clamp for compressing the spring to remove and replace the clips on the long rod ,Just my 2 cents worth::Thanks for the help::

Fwiw, all progressive springs, front or rear, are typically installed tight coils up. This is to reduce unsprung weight; the tight side is noticeably heavier as it has more coils.

Gidday Folks,

I just replaced my K1100LT springs today, about 3 hours ago actually so it is nice and fresh in the old noggin.

Yes the original progressive springs where tight coils up had done 155,000kms I gather as they were shot, I had replaced the fluid about 12 months ago when I purchased the bike so the fluid was clean.

I put Race-Tech springs back in and used 15w Motorex which was red in colour and the difference in handling was great, the bike now rides through bumps and rough road instead of crashing down into it.. Big improvement.
