Crank Case Breather Hose Question
On my 2019 300 EC I found two hoses near the cylinder. One on each side coming from the PV housings. They both were connected two the air box.
According to the race prep recommendations I removed them and plugged the hole in the intake rubber. I always find a drop of oil coming from the left hose. Sometimes it is a bit thinner and obviously mixed with water sometimes it is pure oil. I also had this on both other 300's I had but not as much as on my actual bike. Bike is new (9 hrs) and runs very well otherwise. Compression is fine too. Reason to worry? PS I cross posted my question on TT Forums as well... |

The left hose is the power valve chamber drain.
Some residue is normal. The right side vent hose- pointing up- is the transmission vent. |

Thank you GGman, could be due to the fact that I was running 40:1 the first tank for running in... So more oil than normal.

Oil is good. 40:1 -is fine and brings benefits of reducing wear for little extra expense.

I think we've once discussed oil ratios. I normally run 60:1 and even 80:1 and never had a problem.
Currently I run 50:1. |

That's true. I am mostly in the lower to mid range but on straight sections I let her rip from time to time. On the playground(s) I normally ride WOT in 5th and 6th is possible for about 5 seconds |
