I have a 2015 XMR 800 and was wondering if anybody can steer me in the right direction. Yesterday I started up my bike to let it warm up because it was sitting for a few weeks. After idling for 10 mins I noticed smoke coming from the engine area and looked and found a small twig smouldering sitting on the frame under the motor. I thought this was strange. Today I checked the oil and it looked clean but looked very drippy. The oil had a gasoline smell to it. I don't know where to start, I'm thinking changing oil first. What should I look to fix? Any suggestions would be great. The bike only has 41 hours on it!!

That's weird. If it was a carbureted unit I would say float stuck open but with Fuel Injected unit it should shut fuel down when turned off. Definitely change oil, maybe fuel filter is a good place to start. If you got fine solids thru into injectors they might be passing gas thru. Really stumped me with that on though.

Air filter, plugged or restricted? Does it idle alot, or idle and get shut off without getting run hard? Leaking injector? Short trips and lots of idling can cause fuel in oil.

Thanks for the quick replies, I checked the air filter and its clean. I've only been idling the machine and not riding it since I didn't have any opportunity to take it out on the trails. I figured I should start it up every once in awhile just to keep things moving instead of letting it sit. It's been at least 3 weeks since I've started it up. How do I check if I have a leaky injector?

When the quad is shut off the fuel system will/should hold some pressure (51psi optimum). So if an injector was leaking it would bleed off that pressure & fuel into the cylinder. Can you pull an injector & check by turning ignition on & then off. if it's leaking off it would probably dribble fuel. This is my GUESS. Anybody else agree/disagree. Does injector have to be grounded to activate?

Some gas and or water in the oil is common enough to be considered normal. This will "boil" out each time you run the vehicle at operating temp. More short trips, startup..idle..shutdown cycles, or long periods sitting will make the issue more noticeable.
There is likely nothing amiss as far as injectors go, you just need to get the engine to operating temp for a bit to keep oil clean. Instead of starting and idling, do a lap or two around the yard. This will solve the problem and coat/lube parts in diffs and gearbox protecting them as well.

I totally agree. Change the oil and start fresh. Then try what ichabodcrane said. Monitor your oil and see what happens. Alot of the putzers end up with gas in oil. Happens to outboards also when they troll all summer and never open them up. EFIs have a "choke" or "cold start" programed into them. If you never get past that duration and do alot of start and stopping it will actually dump the xtra fuel past the rings and into the crankcase.

If your not "making" oil there's not enough gas in the oil to cause a problem. Pay close attention to the dipstick, if it rises on the dipstick your making oil. Otherwise a little can be expected due to your riding style and will evaporate once the engine gets good and hot.

Taking my 650 max xt to the dealer on Monday my crankcase was so full of oil and gas that it almost flowed out of the dipstick hole when removed. I'm 2 months away from my 2 year warranty running out. Talked to the dealer on Saturday morning and he said something is wrong . hoping to get it back for the 4th of July weekend for a couple of days of riding, we"ll see how this goes.

talked to the dealer today, they said it had a leaky fuel injector and both replaced under warranty,get to pick it up friday, just in time for the weekend ride. They said not a common problem but does happen. lesson learned to check oil level EVERY TIME i go for a ride.

I know this is an old thread I just wanted to share a recent experience. My new 2019 Outlander 450 had gas in the oil purchased year end close out this 2019 so I just assumed quick start and shut offs for customers for a year. Also I wasn’t sure what break in oil smelled like. After the 8 hour mark mine began a vibration on deceleration. I immediately changed the oil and filter. The slight noise went away. I’m thinking it just needs some good country running. Problems could include scoured piston rings from top cylinder rust, leaky injectors, or just quick start and shut offs. I have until May for warranty. If I learn what the problem is/was I’ll post back.
