help

seafoam will make it smoke like a mother,not sure if it helps but,it is not recommend i believe to use on atv/mx cuz of the dirt involved,if it is going to clean your tank/carb,then where is it going to go???? THROUGH YOUR ENGINE :)
 
Ok hello ppl it was the float runs great fast to o and I drilled. Some hole on my air box on the top side for a little more air
 
Now you will have to up the size of the main jet and do a plug chop to confirm.

The engine will now be running lean!
