Excessive crankcase pressure
I'm having trouble with oil and smoke going into the air box stalling the engine. I unhooked the s shaped hose off air box and the bike runs fine, but What do I do about the base Pressure I heard that's is a common problem with the 06 ninja something called the internal breather tube. I wanted to know could this be the problem and not bad piston rings and if so is this an exspensive repair the bike only has 7k miles on it so I don't think it could be the rings. Any help and advice wil be appreciated thx

Using deductive reasoning, if the bike stalled, but then ran fine when you disconnected the breather hose, then that means the hose itself is blocked. If the crank is blowing smoke out of the breather then the rings are probably bad and it's cheaper to replace the engine. |

The reason I specified 06 was because after a little research I found this was a common problem with the bikes manufactured in that year breather tube not connected properly possable recall and the smoke is more like an oily mist and when you hold your finger over the hose coming from the crankcase you can feel the pressure build other than that the bike does not smoke from the exhaust
