Motorcycle Repair: Dirt bike

Question
I have a 2001 yz 125 and it is super boggy in first and second I rejetted it help a little but it still really boggy what could this be from or how can I fix

Answer
Sounds like the Carburetors are gummed up from old gas.
Try some Seafoam in the fuel to see if it can clean the carbs up.
You can get Seafoam at almost any auto parts store.
But make sure to use it per instructions...
