all help is appreciated. this 2007 Roketa 150cc go kart has been a good one besides constant cable change outs. now here's my latest problem. hope you can help out. it smokes alot-seems to be burning the oil AND there is a 3/8" hose that looks like it comes off of the cylinder that dumps good oil straight to the ground when it's running. oil levels are fine before startup and then virtually drained after it's running. do i have bad rings, broken piston, or what? i thought about selling it as is but i enjoy riding this go kart.

 

With bad rings you could blow oil out of the crank case... Could you post a pic of the hose and where it comes out of the engine?

 

mywifesquad, i finally got some pics under an album under my name, but i still haven't figured out how to hyperlink/paste them to a reply. but if you'd look under my name and album, you'll see the GY6 pics you asked for. sorry for the inconvenience.

 

Thats the breather from the valve cover... Id guess the rings are bad and its pushing the oil out the breather... you could try routing the breather up rather than down and see if it slows down the oil being lost.

 

i presume i would need to send it to the shop and have it rebuilt?

 

Yes... Id guess it needs rings but might need a new piston, bore and rings..
