Just completed a 50k complete servicing of my 93 K1100LT:
Air, fuel and oil filters.
Mobil 1 engine oil.
Mobil 1 140-75 gear oil in the tranny with Guard Dog Moly additive
Red Line synthetic 90-75 with Guard Dog Moly additive
Red Line Water Wetter with 40/60 Prestone/distilled water
Clutch and drive shaft splines lubed with Wurth/Honda magic elixir
Fork oil changed (I'll put the Works Performance springs in over the winter)
Installed freshly rebuilt/reconditioned Ohlins shock that I scored on Fleabay last month
Installed new custom seat by Rick Mayer (still needs some tweaking but I'still have the Russell Day Long to use when I send it back to him for tweaking.)
I actually had most of this done last month, Then my final thing was changing the coolant. Much to my dismay at the very last moment some oil appeared in the coolant - so I had to swap in another ooil/water pump with good seals. What a waste of four quarts of Mobil 1.
Replaced front brakes a couple of thousand miles ago and just did the rear pads so I only have to ride it and add gas/oil for the next 10,000 miles since the PR2s have lots of tread left.
New NGK iridium plugs
Now it just needs a bath.....
