dog,
You cannot just remove the crankcase hose or you will get some oil spitting out the motor onto the part below the gas tank. The breather runs from the clutch side to the airbox and this is vented into the carbs. Who though of this brilliant design is anyone's guess. (Yea, I know, EPA rules) But you can take the breather hose and re-route it so that it actually oils your chain for you. If you pull your airbox you need to still route it somewhere. You can zip tie it so it spits onto the ground or the cahin. The little filter things are cute, but when you think about it, they fill with oil and you have to drain them out ocassionally. So, it is always better to mount the end of the breather at a point lower than the point where it comes out of the clutch side cover.
Do your part for global warming!
I spray a full can of deoderant into the air in my backyard once a week, I have my own personal hole in the ozone so I am warmer than my neighbors. It helps with the heat bills in the winter too.
