Oil drops under side stand on 08 990

Just noticed some drops of oil (3 or 4 overnight) just below the side stand of my 2008 KTM 990 with 30k miles. I'm heading for Steamboat on the 6th and wondering if anyone has any ideas. Like can I make a 12 day trip with a minor oil leak. I'm not mechanical and doubt my dealer can get it in to look at. It started dripping just before I had an oil change a few days ago. The shop didn't see anything during the service. Damn, I don't want to miss this trip. Planning on 2 legs of the UTBDR and the whole CBCDR. I can certainly carry some oil but I don't want to screw anything up. Anyone have any experience with this. Thanks.

Look at the o-ring behind the gear shift sensor. Right behind the side stand bracket. It's an easy fix.

Wash up the area as best you can and spread some talc powder around. Run the bike for a bit, and the source of your oil should reveal itself pretty quickly. Most likely the shift sensor. Less likely, a shifter arm seal or a cracked case. But the leak can come from higher up, like a leaking oil pressure sensor in the middle of the V of the engine.

That is exactly what it was when mine did that. It was easy to spot when you started looking around with a flashlight.

Yes, just keep an eye on it.

I had the same oil spot underneath the side stand on my 2012 990 Adv R. I initially thought the worst: cracked case, oil seal somewhere..... However, it turned out that the Uni oiled foam air filter I am using was over oiled and was dripping some air filter oil from the airbox down the side of the bike and onto the floor. I cleaned up the excess air filter oil from the ground, the side of the bike, and the airbox. I also grabbed some paper towels and soaked up the excess air filter oil from the filter and reinstalled it. All is well now and the air filter isn't dripping excess oil.

Just follow/track the oil trail up the side of the bike to find out where it is originating. I had to take the tank off to get a good view in order to do this.

Could also be that your engine is burping up oil from the crank case into the airbox too.

At any rate step one is to remove the tank and track the oil trail to the point of origin. Most of the time these things turn out to be simple and they make you go d'oh!

Good luck.

Cam chain tensioner gasket

Same thing happened on my brand new 2012 SMT

It turns out the rear cylinder cam chain tensioner gasket must have had a small imperfection because that's where the oil was seeping out of. The shop just resurfaced it (they didn't have a replacement in stock) and no more oil on the floor.

Good recommendation. Had same issue on mine and initially I thought it might be a cracked case due to side stand, as the gear shift sensor is right in that area and oil leaking from it then runs down the side stand relocator.

Thank you all for your input. The oil drip is coming off the side stand relocator mounting bolt so I'm hoping it is the shifter o-ring. It's in the shop now for tires so they are going to check it out. So leak, or no leak I'll be in Steamboat for the rally.

This was the issue with mine; it was an easy fix. Considering how minor, I wouldn't be concerned about the upcoming ride if that is the issue
