I recently bought a 2009 Raider S with about 4K miles on it. The first thing I wanted to do was to change the engine oil & filter and also the middle drive lube. The engine oil change went well (I used to own a Road Star....).
Next, I removed the drain screw on the middle drive cover to drain it and nothing came out. So, I removed the fill plug and stuck my finger in the hole and could not feel any oil. Plus the cover was rather warm. So, I fgured that it must be low on fluid. I put in some W85/90 gear oil and was able to squeeze in about 12 ounces. Still, no oil felt when I stuck my finger in the fill hole.
Now, I realize that I removed the WRONG drain screw. There are two "drain screws". Actually ONE drain screw located about center/bottom of the cover and it is almost covered up by the rear break valve. The other screw. located about 1" below the fill plug is for checking fluid level when the bike is vertical.
Well, I had the bike on the side stand when I removed the drain screw (actually the level check screw) and nothing came out, which is right and proper. This is why I thought the fluid level was low and added fluid.
Here is my issue. I now have gear oil flowing out of the middle drive, from somewhere, most likely do to my overfill situation.
1. Is there an opening somewhere in the middle drive that allows excess oil to escape?
2. Can my leak be corrected by draining the middle drive (using the correct drain screw this time) and then refilling with the amount specified in the shop manual?
3. Should I remove the middle drive cover, replace the old gasket with a new one than then refill with the amount specfied in the shop manual?
