well a banshee is a two stroke motor which means you have to mix gasoline and oil together Use a fully-synthetic 2stroke mix, such as potoline MX5 for untuned bikes or MX7 for tuned bikes (ie bikes with exhaust system)
24 to 1
it should be 24:1 if your using yamalube 2 stroke oil
About 36 to 1 or 40 to 1
I run a 50:1 ratio in mine, with slight mods.(jetted and pipes) I have a stock 01 and mix is 300ml to 10ltrs
3 Oz per Gallon
50ml of oil to every litre of petrol
Around 32:1 depending on the quality of the oil.
Transmission oil? It goes in where the dipstick screws into the RH engine cover near the kickstart lever. Top end oil? The Banshee runs on premix. You mix oil with the gasoline, put it in the fuel tank.
Check your fuel off / on swich. Pull the to screws out and check the filters.
If the banshee hasn't been bored or altered then there is one ratio mix. The gas to oil ratio mix should be 40 to 1 .
Oil fuel ratio for z 1983 Yamaha IT should be listed on the oil bottle. The most common ratio is 50:1.
in 2002 and 2003 they did the switch but some people might sill say it wasnt truly fuel injected till 2004
