My friend keeps his 94 Banshee in my enclosed trailer.

Usually, he forgets to turn the fuel off and it immediatley starts leaking through the overflow hoses on the carbs.

What causes this and how do you repair it?

 

inspect floats in carbs . if ok then ck needle and seats for debris or wear.. if worn replace

 

I have a yamaha grizzly I just carried to the shop with the same problem, write me back next week and remind me and I will tell you what the problem is/was. The tech told me it appeared to be the float in the carb and that the hose allows the gas to escape insted of letting it go into the motor. You had better keep check on the fuel shut off mine went bad and it showed to be in the off position but one day I went in the garage and I had lost a full tank to the floor
