My brother called today and told me, "I found a yellow dipstick on the lower right side of the motor." He doesn't have his owners manual with him (he's at our parents house) so I was hoping you guys could tell us what it is, what type of fluid to use, and how much. I'm assuming it has to be the F-N-R gearbox, but I haven't seen it myself. Thanks!!

 

you are correct.

 

Should be the gear oil dipstick, partsland.com has a breakdown of the polaris atvs. he can look at the transmission and should see the dipstick.
