Alright before I begin YES I've used the search function and NO I didn't find my answer. Ok so now that's out of the way here we go!
My 70 T120 is SPEWING oil out of the tank vent (aftermarket tank) and primary breather. The entire back half of the bike is covered in oil including the rear wheel. It only seems to do this at higher speeds 50mph+. Now whoever built the engine before it fell into my hands ran the rocker feed from the oil pressure switch. (yes I know that's wrong and parts are on order to fix it, changing the tank out as well) My question is could this be putting too much pressure to the tank/crankcase causing this oil slick spraying out of my bike? The primary breather is an off/on problem with this and doesn't spray as much as the tank vent.
