Went out into the shop yesterday and saw a spot of transmission oil under the LH side of my White RZ. Another aftermarket neutral switch. I took it out and cleaned it and the cavity in the case thoroughly with brake kleen, then applied a generous coat of Permatex anerobic sealant and reinstalled it. The picture is one hour after the work. It was bitter cold and windy here today so I stayed in the house. I will know tomorrow. If it leaks I have a spare Yamaha factory switch in a spare motor. We will see.

I had the same issue. Put a new oring and it seems to be better. Not as significant with the leaks that I can tell
Do not underestimate the power of a two-stroke.
