My yami is way to heavy on petrol i mean it would last a hour on a full tank ! how can i make it better?is there some sort of efi ? and would bad rings cause this? (i think i got bad rings!) thanks
 
if your not dumpin fuel out of the carb overflow hoses that's weird for normal riding. is there gas pooring out of the exaust or anything. that sounds really strange. I get about two hours of pretty hard riding out of mine with a stock carb with a 330 jet. are you fouling plugs?
 
If youre drinking fuel, your jetting is too rich, something else isnt right.

I drank fuel with my PWK36mm carb on there. I put my PWK28mm carb on there and now I get as good of mileage as a stock one.
 
Could be carb size. I'm just gonna throw this out there. In a extreme case like this you might have a air leak and adding more/enough fuel so it will run. That might use that much fuel, idk.
 
you check the jet by pulling the carb off and diassembling it......the jet will have a number on it....thats what size it is....
