Punctuation is your friend. If you want to know what crank you have you need to open up the motor. The stock tranny is a 6 speed, so if its only a 5 speed you most likely have a override transmission. Buy a quality brand two stroke oil and mix 32:1 or 40:1 imo.

I know about the 2 stroke. I was wondering about the gear oil. Yamalube or does it need a heavier oil? I know it's a 4 mil crank. I'm wondering what cc it is with a 60mm bore and the 4 mill crank and if it would be good to run for a long period of time with a cool head that has 22cc domes.

I use Gear Saver 80 wt tranny oil, a cheaper alternative is ATF type F. With the ATF you will have to change the oil more often. A 60mm bore with a 4mm crank would be about 328cc's but a stock banshee has a 64mm bore. A stock bore with 4mm crank is 373cc's and they make a good duners, however what really determines the performance is porting on the motor.
