Tri Zinger Question? Help Please!

[2K4EVOVIII]

Hey guys i have a Tri Zinger YT60 that im rebuilding for my son and was wondering in the rear end if you have to fill it will some kind of oil? Or is it injected in somehow? Or do you put grease on the gears or what?

Thanx

They have oil in them from yamaha. Not sure what viscosity, probly 80/90. I put a grease fitting in mine, & shot some real good moly grease in there. My boys run the ass off of that thing & I have never had a problem In the 5-years I have had it. You can push gear oil in the vent line, but it's a slow process. I would put a grease zerk In If I was you.
