Couple of questions for you guys
Can primary oil leak into your transmission ?
I use spectro synthetic oil’s in my transmission/primary/engine.
I used the proper amount ( or at least I thought I did ) and grade/weight according to the manual in all three.
I could have sworn I only put 20 ounces of the spectro full synthetic platinum 75W140 in the trans last fall. I still have what’s left of the quart sitting on the shelf and according to my math All I used was 18 1/2 to 19 ounces. But I pull the dipstick out and it’s over full this is why I ask. I am getting a leak onto my floor after riding it seems to be coming from the overflow tube on the transmission but I can’t really tell because the space between the primary and transmission is so tight and the overflow tube doesn’t come out the bottom all the way. It’s actually dripping off the lower corner of the Engine oil tank Kickstand side And the overflow tube looks like it ends right there in that area. Now I know it being over full can cause this and before riding it again I plan on draining some of it out so it’s only to the full mark with the bike sitting in the upright position. The drips on the floor are pink the same as the spectro 75W140 oil. I don’t know if it’s possible for the primary to leak into the trans to cause this over full condition. I would think that if it was going to have a leak from one to the other it would be from the transmission to the primary and not from the primary to the transmission as the transmission oil level is physically above the primary oil level and the shaft seal.
What really throws me on this is the fact that I did The fluid changes last fall and I have done a bunch of riding since then and it’s just now showing up. Plus it being over full and I still have 12 1/2 to 13 ounces of oil in that quart I used sitting on the shelf which tells me I only used 18 1/2 to 19 ounces. I do know one thing for sure with that oil being so clear it’s just a slight hint of pink it’s hard to read on that chrome dipstick.
Well anyway Guys I’m gonna go out to the shop in a little while and drain some of it off and clean it up and take it out again tomorrow and see what happens.
Just thought I’d throw this up here and see if anyone had any insight on this.
Thanks
PS
Just for shits and giggles I think I’ll pull my primary inspection plate off and have a look see at the oil level while I’m at it.
