TE/TC oil leaking

I normally keep my bike on a stand but over night I left it on the kickstand. When I went in in the morning I found some oil on the floor under where like the gear shifter is. It looks like it is coming from behind the sprocket to me I took some pics. I plan on pulling it chain and sprocket off later but any ideas what it could be? I have it washed and up on the stand now and I don't see anything. I'm going to put it back on the kickstand in a bit to see if it leaks again

countershaft seal id say. very common issue & easy fix I believe. normally caused from chain being too tight I think

buy the replacement kit,seal , o ring and bush, they leak over time

simple CS seal change. pay attention to keep proper chain tension. Ive seen way too many guys with guitar string chains when suspension is compressed. bad for suspension very bad for drive system stress.

Good trick to install a new CS seal is to use the CS sprocket itself to square it up, then use a large socket up against the CS sprocket to drive it in. Takes 30seconds and its nice and square that way.

I ordered a new cs seal. Thanks for the help and the tips

If you've changed the front sprocket recently, just check that the circlip has clicked home fully. I had the same issue recently and realised that my circlip hadn't clicked into the groove as far as it should have. Problem sorted.

Dont just do the CS seal.... Do the bushing and oring.... also some aftermarket CS Sprockets are not the correct width and need a washer to keep tension on that bushing

I have not changed or even taken off the sprocket yet. The bike only has 475 miles on it. When. You check the chain tension do you do it with the bike standing on a stand or with the suspension compressed?

Adjust it on a stand. The amount of slack on the top run, to the left of the chain guard, should be approx 55mm, or I just go by 3 fingers. The owners manual illustrates exactly where the measurement should be taken and also the correct amount of slack. Although you have a low mileage bike, if the chain has been too tight as other posts confirm, this will lead to oil leaks.

Yeah I followed the manual every time that I tighten the chain. It seemed to stretch a lot the first two to three hundred miles but hasn't really stretched much since then. I did buy the whole moose kit not just the seal.

I had a similar leak on mine a few months ago and it has been good for the last few rides with a simple cleaning and greasing. I pulled the front sprocket to examine the three main components in there: seal,collar and oring. All looked good so I cleaned everything up well (use several q-tips to get in the lips of the seal) and then greased the seal WELL along with the oring and collar. So far so good. 20 min max and you are in and out.

i don't go with this chain to tight will stuff up the CS seal, the chain will stretch or break before the CS spline bends flex's or the bearing moves, if it was true the CS bearing in the box would stuff up pretty quick, the rubber seals have more room for movement than the CS spline
I have just split the cases the CS spline is held in by 2 good sized bearings and no way will the CS spline flex with a tight chain

Could over filling the bike with oil cause the leak? I have always put the 27oz that the manual says but today I took the oil level screw out while I filled it and the oil started coming out at about 20 oz. Should I continue to put what the manual says or should I stop when the oil comes out?

I'm not sure if the manual recommend amount of oil is for a "dry" fill or not. There is no way to get all the oil out on a change. I have been wondering if too much oil could cause this leak but I'd guess it could. Some guys are only putting 700cc in when the manual calls for 800. They don't have leaks and the check screw indicates ample oil.

Side note. I hate those check screws. They can be easy to strip. I typically go by volume and leave the check screw alone.
