Might be an odd question...
But I just fired up a moto4 that has been left sitting in a garage for the last ten years. It runs like new but am confused with the hoses left hanging under the gas tank.


The clear gas line running from the carb next to the throttle screw is not attached to anything. The line from the top of the gas cap is not attached to anything also left hanging. The breather line from the crankcase and rear diff are also not attached to anything.


Any help would be appreciated seeing the manual is not much help or does not mention a charcoal filter of any kind

 

It is years since I worked on an 80s Moto 4 but most Quads have breathers that just run up and end near the fuel tank. They all have a dangling pipe from the filler cap, on most there is a hole in the plastic somewhere to poke the end into. The engine breather does go somewhere though, normally into the air filter box.

 

I had it out on a trail today. Ran perfectly other than horrible gas mileage soo it has something to do with mileage. Anyone, anyone ?

 

Hose on gas cap goes nowhere, overflow tube of carb just goes nowhere. Crank and diff air vent lines go to air box.
