Good morning all....

Say... I thought someone ( Phil or Scott maybe..? ) had written a simple detailed ( ie: step by step ) "Tech Sticky" on the changing of fork oil procedure, for K75, K100, and K1100... Am I wrong or have I been smokin' something funny ?? IF we dont have one, we should, given all the new folks around lately...or, IF we do have one, where is it ??

Best regards all.........// Ernie in NH

Hi, Ernie,
I'd be happy to do it if there is a need. Right now, my advice would be:
1. Don't drain the oil without first loosening the fill plugs.
2. Have new drain and fill gaskets or "O" rings on hand. You may want to reuse your old ones, but Murphy's Law says if you don't have the parts, you WILL need them!
3. Retighten the fork drain plugs snug. Two grunts and a fart is NOT the correct torque for these small plugs! I tighten them (on the K75's with alumin(i)um gaskets) until they are snug, then a bit more until I feel the gasket being slightly compressed. I did the same on my K1100LT's (with the small "O" rings).

Hi Phil...

That's great and thanks for the advice... At some point however, the procedure would be a great addition to the "stickies" for everyone to use as a resource.

As you no doubt know, we all think about you every day and hope that your condition will begin to improve in marked strides. Aside from your personal humor, technical expertise, and artful hand in the "spaghetti kitchen",, you have enriched our lives in more ways than even you could know. Be well my brother, ride safe, and see you in in May for sure !!

VERY best regards as always...........// Ernie in NH

I am conflicted about the amount of fork oil required on a 96K1100lt when both forks are completely empty - I.E. I replace seals and therefore cleaned out reservoir completely by removing the "innear tube - Black".
Anybody know what this quantity is?

Hi, Micky77,
If I remember correctly, for new or rebuilt forks (no oil at all in the forks) the correct amount is 400cc per side. For a fork oil change, one side (I don't remember which) is 350cc and the other is 400cc.

Let me add that if you haven't done it lately, you would be well advised to pull the fork lowers off and actually clean them out. Once you see the crap that comes out of them, you won't ask why.
A bottle brush and a can of spray brake cleaner works for me.

Sorry Jeff, but I am not sure what you mean by "fork lowers"? I did take the fork slider off to replace the seal and dust cup which revealed a lot of debre in the bottom of the slider tube. This I cleaned out. So did I miss another debre collection point? Thanks in advance.

No, sounds like you got it. The lowers I was referring to are the sliders.
Everytime I work on someone's bike I make a point of showing them the goop that gets past the fork seals and ends up at the bottom of the sliders.
Could be psychological, but they sure seem to move a lot smoother with the goo gone before the new oil goes in.
