Motorcycle Repair: ATV smoking, air fuel mixture, fuel leak

Question
I recently aquired a YMF 60 yamaha atv. It runs okay, buts at full throttle it seems that the choke is on and it really smokes. I have replace the fuel and oil. I also notice a fuel leak at the carb.  

Answer
Hi Johnny,

The carburetor main jet may need tuned to lean the air-fuel mixture. Check the air filter for intake restrictions. Clean or replace air filter as needed.

I recommend having a local shopinspect the problem for you.
