About two months ago I bought a 2015 Yamaha R3 as my first bike with 3500 miles. I have since put 700 miles on it and changed the oil and oil filter approx. 400 miles ago. The other day I was riding and a lady pulled out right in front of me and I layed my bike down going about 20-25 mph. I have the bike in my garage now, I’ve been assessing the damages and I revved the engine and around 5000-5500 rpms and it makes a whooshig sound and the exhaust spits oil and produces a white smoke, but not a copious amount of smoke. If anyone could point me in the right direction that would be fantastic! Thanks!

When the bike went down oil probably got into the air box thru the crankcase breather.
Then the oil goes, air box to throttle body to cylinder and out the exhaust, or something of the like.

There is a slip on 'drain plug' on the air box. It's located at the bottom of the air box on the left side toward the front.
Pull it off and see if oil comes out.

If what I've said is what's happened you probably should check the air filter element then change the spark plugs AFTER you're sure all of the oil is out of the air box.

Also, check to be sure you don't have too much oil in the engine.

Let us know how it goes... :)

Sounds great! I’ll do that when I get home from school today! How do I go about checking the quantity of oil in the engine?

Most Yamaha's have a sight glass. Bike has to be level and usually it is the middle of the glass. Check your owners manual for more details.

What Critter said .. plus:

If you start the engine cold then shut it off, the cold oil will not run down from the top of the engine enough to get an accurate level check.
Ideally, run / ride the bike till fully warmed up, shut it off, wait a few minutes then check the oil level.
Your bike has a sight glass on the lower part of the right engine side cover. (Right side of bike as you sit on it).

Thank you for all your help, that last question was a dumb question, I rode today for about a half hour (still missing my left foot peg) and the bike sounds fine, i took the exhaust off, there was a little bit of oil sitting in the bottom of the pipe, I drained it, and its running well now. I knew there was an oil glass to see how much oil was left in the bike, I meant to ask about how to check to see if there is oil in my cylinders, but it appears the problem has been solved by itself. Im planning on having the bike inspected in the next week or so by my friends dad which is a mechanic to get another point of view on it. Thank you for your advise and I’ll be coming back to this forum more frequently for any questions I have!

Sincerely,
Andrew
