450 bogging and dying when given gas
Howdy fellas, ive got an 87 450 which i bought at auction as a project which had been sitting for 3-5 yrs. The bike had not been prepped for storage so we ultrasonic cleaned what looked like black tar from the carbs, and replaced the petcock as it was leaking and was damaged. now, it would appear the bike is fueling correctly, it starts first if not second try; but whenever its given gas it just bogs out and dies. when the throttle is applied in a controlled manor, its able to idle up a little before dying. the previous owner chopped the mufflers and removed the baffles, so the air/fuel ratio is incorrect, but we've adjusted the carbs from the adjustment screw on the bottom with, as well as the idle screw but still cannot seem to get her running right. ive read about another adjustment screws covered by whats usually a brass welch plug, but i didn't want to start drilling out plugs before getting someone elses take on it. any help appreciated.
