Oil Leaks: My Crankcase is Spitting Oil!Updated 14 days ago

A customer writes, "My crankcase is puking oil. Help! I vented the crankcase breather down the back of the motor like you suggested and now I'm getting excessive oil coming from what I believe is the hose and higher RPMs -- to the point of it coating the swingarm and sidewall of my rear tire. Any ideas on where to start to get this corrected?"

Well, SH*T. That's not good! 

Luckily, I've encountered this situation before... and out of the dozen or so times people have hit me up with this problem... every single time it's because someone over-filled their oil. You've gotta be really careful when you're filling your oil - there's different amounts for different processes. 

TJ discusses this in detail in this video. 

A few takeaways:

1. Make sure you're putting in the right amount of oil in your bike

2. Check your blow-by; it could be excessive (what's blow-by? watch this: https://youtu.be/V71Jv14_ljk)

3. If that's not the problem it could be a motor issue
