Tranny Leaking like a Basket

[Beachcruiser]

Took the banshee out for a ride today in a wash for about 30 mins. Once I loaded it into the truck I noticed tranny oil was leaking pretty good. There was a puddle of fluid on the case below the sproket, I seriously lost probably 8 ounces within 10 mins. Brought it back to the house and pulled the plug so I would empty out and stop leaking at the unknown place. I took off the stator/sprocket cover and cleaned all around the sproket area where the fluid had accumulated. Noticed a metal plug in the fluid, started looking at the case and found out that it must've popped out. Still not sure where the fluid was orginally leaking from. Could the missing plug be the reason it was leaking? I found another picture of what im talking about and circled the plugs in red.

 

 

Also, last week I went riding and ended up getting a rear flat tire about 10 miles out. from the truck My dumba$$ decided to ride it back like that. Once I got back to the truck the tranny started shifting funny. When i finally get it into neutral, the shifter has alot of play in it.(up and down) It's also difficult to down shift as im deaccelerating. Any suggestion on what this could be?

 

Thanks

Those plugs are for the ends of the shift fork shafts. If you need a new plug, the yamaha part number is 90334-10006. Will definitely leak tranny fluid without it. Would be good to replace the shift shaft seal while you're in that area. Part number 93102-12321-00. Very common leak point. Your shifting problem is probably a broken shift shaft ecentric bolt. Part number 90149-08256. Has nothing to do with the flat tire. You really need to get a Clymer manual. It will help tremendously in your repairs.

your shifting issues could also be caused by your shift fork shaft slightly moving a little bit since your plug came out. i wonder if it either allowed the shaft to move or if it allowed just enough fluid to drain out to quit giving enough lubrication. Either way.....AFTER you fix your plug issue........THEN i'd say check your ecentric adjustment......you want the screw exactly in the middle of the claw ends or else it can make for some interesting issues with shifting...

Thanks for the help guys. I reinstalled the plug and took it out for a quick spin. Shifting is still like crap but the plug seemed to hold up fine with out leaking.

 

Do i have to split the case in order to fix the eccentric adjustment/shaft or could i do that from the outside??

No, it's inside the clutch cover. Drain the coolant, drain the trans oil, pull the clutch cover. Problem should be obvious at that point. If you keep riding it, and that bolt really is broken off, sooner or later that bolt is gonna go bang, clatter, clatter, crunch, kapow. Technical terms for the equivalent of jamming a tire iron into the bicycle spokes.

Appreciate the info starwriter. I'll be checking that before the next ride.
