In addition to changeing Engine Oil, is there a need to change Transmission Oil, Final Drive Oil, etc. I changed all the fluids in late Spring ( used Amsoil synthetic gear lube oil 80W-90) I only drove about 2500 miles in the summer. So, do I need to change oil again as recommended by Clymer.
-
I would check the fluids for color, if you get water past the speedometer drive cable boot at the transmission, you can have water contaminated oil in the transmission .
It ruins the bearings after a few seasons like that .
Before the internet (mid '80's), I had contaminated oil in the transmission and it rusted the bearings to where I had a vibration from the transmission .
I just by chance figured out how the water was entering the transmission .
I now replace the rubber boot, every three years, regardless of how it looks .

I don't always change out every fluid, but it is good practice to do it to ensure that you don't have water sitting anywhere it isn't supposed to be for an extended period of time. Plus, you have the benefit of being ready to roll on that first warm spring day - unless you live on a dirt road that turns into foot-deep muck, like I do.

Thanks for the info. I gues I might as well just go ahead and change the fluids... cost is about ( $35)

Today I changed all the fluids, except brake fluid, on the R65LS. What an ordeal - the veterans here at R65.org know the drill - drained engine oil, tranny oil, final drive oil, drive shaft oil & R&R Filter with a new Mann hinged filter (EuroMotoElectrics in CO worked out well).
On Paul Glaves recommendation, I bought a bottle of Guard Dog Moly additive. Mixed it with my gear oil & replaced all fluids, except engine oil with it. Paul says he's never had a FD failure using it. Felt like the mad scientist mixing the moly to the gear oil. :D
I have to get a decent funnel - loading the transmission oil through the side is challenging - I used a large syringe that did the trick.
Anyway, the bike now had clean fluids and fuel stabilizer in the tank. Unlike some of the lucky ones, winter is approaching!
Thinking about how many oil changes Monte has to perform with his large stable of bikes! ;D

Thanks for the reminder, Ken.
The "new" R100S needs the full treatment to establish my maintenance baseline.
For the transmission refill, I measure out the spec'ed quantity of gear oil. Then, using a plastic funnel with some clear tubing on the business end (and secured with a zip tie) and the other end poked into the trans fill hole, I'll slowly add the gear oil.
I find it helpful to secure the funnel to the bike so I can add a little of the thick gear lube and wander off to other chores. Add oil as it s-l-o-w-l-y goes into the gear box.
As you approach the full volume as stated in the manual, start watching for the "dribble" at the fill hole.
All very high tech, don'cha know. ;D

Another member asked me about how much Guard Dog Moly to mix with the Hypoid 80/90 gear oil - just transfer 4 ozs from a full bottle of gear oil into another container and add 4 ozs of Guard Dog & shake shake shake.

Seems pretty complex to me. I just buy the gear oil in the bottle with the tapered squirt nozzle and graduated markings on the side with a sight line.

Hello !
We all own a twin cylinder engine. To fill the gearbox, the easiest way is to let the bike on it's right cylinder. this way, the filling hole is at hand, and the oil won't leak on the ground.
I was told you can put one liter on the box and it make the gears go smoother.
So buy one liter of oil and pour it in using my method...
Do not forget to put the plug back before getting the bike up ;D

I've saved the tapered spout from old gear oil bottles, I use a length of clear tube on the spout, put the other end into the gearbox fill port and fill to overflow .
