I need some help. Blasters leak free new rings , reeds , gaskets etc. Floats set around 20mm to 21.5 and it bogs and sputters a little around 3/4 to full throttle it's got a 3mm stroked crank 67mm piston, fmf with toomey silencer lid off (still have the lid).... my elevation is 670-700 ft... I have a 270 main in it and 32.5 pilot.. trying to solve the bog/ sputter issue and need some advice where to go with jetting. The only jets I have atm are a 270 , 300 and 320 I tried the 300 and it did seem better but it was rich.. it gets around 40-45 degrees but varys each day can be warmer or can be colder... Id rather be jetting for slightly warmer weather but need you guy's thoughts on what I should do to overcome this problem and get my bike running crisp
