You need to tell us the year of your bike as there are 2 carbs and if it is a CA model as these have different jets. My 2014 CA carb has a 126 mainjet as stock. I am not sure what older carbs have. Here is a list of jets.

If you have particles in your gas tank you can plug up a new carb especially the pilot jet as it is so small. Or if the gas is bad. The gasahol here in CA goes bad incredibly fast and seems to affect the pilot jets.
