i have a 1982 gl500 that if i accelrate slow its ok till i reach 4500-5000 rmp then it spits and sputters in the right bank. if i pull the choke out slightly it runs fine, i have replaced the fuel filter in the petcock and pulled both carbs and cleaned them,pulled all jets and cleand them sprayed carb cleaner through each port in the carbs and they flowed freely. i replaced both air cut off valves and replaced axcelerator pump. pulled both plug and there burning clean. i have a grimlin some where im chasing i cant seem to catch. i normally restore gl1100 and gl1200 which i have rebuilt several of from ground up. but this 500 was one of my starter bikes i just recently was able to get back after it sat for a year. when i owned it befor never had a problem from her,can anyone point me in a direction to run with this im drawing a blank,i was thanking on checking the voltage to see if the stator was weak and not powering the coils good but like i said it runs fine with the choke part way out
