You can use Amsoil 75w-90 Severe Gear in the transmission. I use it in my 250r

 

i used to us maxima,but the way u do this is drain all the old oil out of the crank case by removing the oil plug,not sure if a banshees is on the bottom or the side,anyway put the new oil in,never mix gear oil with gas.[img]i/expressions/face-icon-small-smile.gif[/img]

 

Banshees plug is on the bottom almost in the middle of the crank case. Its the one that hangs the lowest.
