125-200cc Gearbox oil question

Hi all, I just changed the gearbox oil in my '09 WR125. I normally don't put the whole liter bottle of oil in, but today my thoughts were wandering as I stood there pouring it in and I emptied the whole liter of Belray in to my gearbox. Is there any reason to drain a bit back out, or just ride and not worry? Thanx in advance.

Thanx, I sort of vaguely remember doing this before without consequence, but I thought that I would make sure. It will be interesting to see how long my clutch lasts. I ride the bike quite a bit, probably six to eight hours a month. I change the gear oil every second or third time that I ride. The bike seems to be holding up well. I frequently slip the clutch with a handful of throttle when I'm trying to wring more out of it. I often see a bit of grey stuff in my used oil, but I assume that this is how it is supposed to be.

Personally I would run the recommended ammount. Do you have a slurp gun in your garage? They come in handy. If you don't stop by the 99 cent store and get yourself a turkey baster and put a piece of hose on the end of it. Works great for adding a little radiator fluid or sucking out a couple excess ounces of oil.

I believe the 125 takes .8 liter. Putting a full liter in isn't that much more oil. I wouldn't put 2 liters in...but that little extra isn't enough to cause any problems.

Some people might actually reccommend it.
