I just had a majority of my bike powder coated and when I got it all pieced back together and started it up some white smoke came from the engine. The bike is a little low on oil but I’m hoping it’s some of the powder coat warming up and burning off but seems unlikely. I also had the exhaust ceramic coated black but like I said the smoke was coming from the engine. The only thing I had powder coated in relation to the engine itself was the cam cover.

Anyone know what this could be ? I obviously am not riding the bike until I figure it out. Bike is a 2017 RGS

Thanks in advance.

My guess would be residual oil from the cam cover install, whether some dripped out of the cam chest and ran underneath the motor, or maybe you had some oil on your hands when you installed the cover. Could also be a cleaner if you used one after install.

That’s what I’m hoping for. Oil obviously came out when I removed the cam cover but the smoke seemed to be coming from the top of the engine. White smoke usually is only oil burning correct ?

Did you catch a whiff of the smoke? That's usually the tell tale. White smoke could even be electrical, Everything has a distinct smell, like when dropped eyeglasses get wedged between the frame and the header for instance. Have you figured it out yet, and/or did it stop doing it? Any chance it could have been some residual on you PC'd parts?

I haven’t figured it out yet. I pulled the bike out of the garage and started it up again. I couldn’t see smoke this time (I was outside) but the returned and it’s kind of mechanical? Idk how to describe it.

I’ve smelt burning oil or oil residue and it doesn’t seem to be that exactly, however is similar.

I haven’t made any modifications to anything internally and the only part of the engine I’ve exposed was the cam. I had a plastic bag over it to keep dust out while the cover was getting powder coated. Other than that I removed the exhaust and but nothing else that isn’t cosmetic.

I would recommend that you do the following with a cool engine. Put on a fresh pair of latex gloves and a new paper towel and run it around the engine everywhere you can reach and see if it picks up any liquid.

If the smoke looks like it is coming from the top of the engine you might want to remove the fuel tank so you have a better view.

It could just be burn off of something that got on the engine from the work you did. I would go over the list of what you removed to get the parts off and back on that were worked on. A bright light helps illuminate things you might not catch as well.

I wrapped pipes on a previous bike and there was a lot of smoke, but I knew what it was from and expected it. Not expecting smoke can be disconcerting.

Probably dumb suggestion - but was it taped down? Any chance there was a little tape or piece of bag left???

Along with the other suggestions - make sure the air cleaner vent is not blocked - if it is it will blow a lot of white smoke.........

White/bluish smoke is generally oil, but if it is oil, you're gonna smell it. Ain't no mistaking the burnt oil smell.
Give the bike a good washing & see if that cures it. Could just be the new powdercoated cam cover causing it. If it is, it'll dissipate in time.

Update... I washed the bike today and rode it for a little while. Smell was still apparent however no white smoke. No abnormal issues with the bike and oil pressure is “OK”. Hoping it’s the cam cover.
