hey yamaha fans,
i tried to to an transmission oilchange on my yt 3600 i thought i foud the drain plug but as i screwed it out is more looks like an back preassure valve with a spring and a metall ball. anyways lot of oil came out

So by trying to put that plug again in i first thought the ball was correct inserted, but after fillig oil again in the gear won´t work so i checked it again and the ball was missing.

Is there a chance that the ball can be fallen in a wrong hole ? or looks it more like it felt down and i dind´got it but i searched the complete garage....

So if it seems that i missed the ball on the ground does anybody know wich diameter of the ball  is the original? it seems like somethng between 8 and 12 mm

i have some pics in my dropbox
