[satts]

Hi everyone i have a freshly built stock motor stock pipes too. Only mod is uni pod filters. Bike wont start without couple drops of gas on each filter then starts 1st kick .idles fine has very light bog jus off idle but is spitting alot of black oil out the left pipe and what looks to be gas out the right pipe. Motor isnt leaking held 8psi for 10 mins compression is 135 bogh cylinders jetting is 290 mains 25 pilot 2 turns on airscrew and needle middle clip carbs are in sync .so i think anyway .any help is appreciated

Run the air screws in and see if that helps the start and bog.

Did you use assembly lube or similar to assemble the motor?
