@HELP

Sorry to bother just wanted to ask what this part/tube is that feeds in the air intake coming off the air box and if it’s normal to have oily residue around it?

Thanks
Drew

I believe the one your talking about is the oil breather hose. It's for crankcase ventilation. It's normal for it to have some residue.
