Just pulled mine from the air box. Stuffed some PVC replacement foam in the end and threaded safety wire through it and the hose so there's no possibility of it getting sucked in. Then rerouted up under the seat. Around battery and tied it near the o2 sensor at top of airbox. Question is what will happen to motor if this tube gets kinked or flow has been constricted too much. Blown seal or something? Will bike run bad when plugged before something get ruined?
nothing, it will just use energy to over come the crankcase pressurization which will then not make it to the back wheel
can you feel this power loss -
I remember about 10 years ago doing some work on a Honda CG125 single cylinder road bike
I took the oil filler cap off the engine whilst is was running, and it started sucking and blowing out of the oil filler hole because it didn't have a crankcase breather system, so engines have in the past not had crankcase breathers and been perfectly OK
