Carb cleaned up like new, it was pretty much perfect before. Float level was a bit high so we lowered that. Bike fired right up. It still shuts off when I do long Stoppies, and then takes ages to start back up. Super annoying. Sent from my SPH-L710 using Tapatalk ---

Is the carb gravity fed? Ever smell gas after doing stoppie? ---

Yes, I think it is. And yes. Gas sometimes flows through the gas cap when I do Stoppies. Other than that, no leak… I should just stop goofing around… Sigh Sent from my SPH-L710 using Tapatalk ---

Metal tank, so there is no traditional vent. It comes from between the cap and tank Sent from my SPH-L710 using Tapatalk ---
