Totally new to the forum but thought this would be the best place to figure out my issue with my CB750. My 1975 CB750 started to leak oil out of the overflow tube when riding. The oil is at the right level. When the engine is running the oil really doesnt drip out but as soon as you start driving it the oil starts to come out and then as soon as you stop it starts to come out faster. I have read some posts that say to possibly attach the over flow to the back bung/ nipple of the crackcase. Any thoughts on why the oil may be coming out the over flow or if connecting back to the crackcase would be a guy idea. Attached is a picture of where the over flow is currently located, its between the frame and engine straight in front of the back tire. Thanks in advance for any help!
