my rear carb when running has gas comming out of top right side runoff hose. its pouring out

float in the carb is stuck, i'm a suzuki tech. clean the carbs

sounds like a float in the carb is stuck.

Pull off the seat & tank, remove the carbs,
remove the 4 screws on the bottom, pop the cups off of the bottom(be very careful when pulling the cups off not to break the gasket)

you will now be able to see the floats, just ''jiggle'' them up & down to free them up.

slap it all back together & run it for a while all should be fine. You will have a lot of people telling u that u need to rebuild the carbs but this is not necessary, moving the floats up & down will clean up the pins. I've been working with bikes & carbs for an eternity.

just hose the bottoms of the carbs with carb cleaner before & after ''jiggling'' the floats & u will be fine to ride another 10,000 miles.

Best of luck to ya.
