So I just bought a 2007 XB12R that has 3700 miles on her. She has an aftermarket exhaust, HIDs, breather re route. The second day I took it out for a ride the check engine light turned on while I was letting it warm up and it hasnt turned off since.

It is leaking oil from rear cylinder near top (common rear rocker box gasket?). Would this also make the check engine light turn on? It isnt super low on oil and it has no sputtering rough idle or anything either. Taking it back to shop I bought it from, but they arent a licensed dealer just a very reputable shop. Theyre trying to get their hands on a cable to check engine codes.

Oh and battery and charging system is fine. Just looking to get any insight to maybe point them in the right direction. Thanks

Trey

Oh and right around or it even looks like there is smoke/steam coming out of the filter in my breather re route? Common or not so common? Only see it smoke a little bit at stop lights.

You can check the codes using a screwdriver and jumpering the right pins on the diagnostic connector, but I'm going to take a bet that your CEL is due to a fan failure or exhaust actuator.

When the oil starts leaking from the rear cylinder, it gets sucked into the fan and ruins it, causing it to fail and throw a check engine code. The leak itself cannot throw a code.

Most aftermarket exhausts do not have a valve in the muffler like the stock pipe, and many times people remove the actuator incorrectly resulting in the CEL, but that would of been the issue since you bought the bike, not a few days later.

Yep! Fix the leak, replace the fan, and enjoy : )

Can't the original fan be cleaned off?

Anytime I read rocker cover leak and breather re-route together, I think check the plumbing.
If that re-route is restrictive, those gaskets get a workout.....

No doubt about it. I had that exact problem soon after doing the breather re-route. I put it down to running the two hoses into one via the "T" on the re-route. Luckily, got the rocker cover gasket and wrecked oil soaked fan replaced under warranty. Never reinstalled the breather re-route for fear of blowing the gaskets again.

so are you saying I should put the breather back into its factory position? I DO NOT want this to happen again as I was quoted ~$650 for everything from the dealer

I'm not an authority on this issue, and Bikelit's is the first post I've read that possibly attributes this failure to the breather re-route. But I figured it was more than just a coincidence that the rocker gasket gives out within a short time of doing the re-route on my 12R. I decided not to reinstall the breather re-route, in case it was the cause. 15,000 miles later, so far, so good! Maybe others can chime in with their view on this.

And to think the only reason I chose not to reroute my breathers was that I was lazy.

I have been running a catch can that is fed with a 1/4 solid line that is connected to the "T", going to the breathers. I have no issues in 17k+ miles on my 12R. I guarantee that there is more pressure restriction in my 1/4" line than a 5/16" rubber hose routed to the ground from the "T".
I should also say that the line going to the can is routed off of the side of the "T", so one of the breathers doesn't have to make the gasses do a 90 degree bend. It flows right through.

I think you would have to really screw up the reroute for it to cause a gasket failure. I've seen numerous bikes over the years have the rear gaskets leak, both with and without the stock breather setup. I am at over 40k miles on one of my XBs with the American Sport Bike reroute kit, still original gaskets, it doesn't burn oil either.

LOL I got that beat.
I did nothing to my breathers.
It cost nothing to do this.
Nothing went wrong.

Yay team apathy!
