running issues with 83 suzukimatic

[chris lawson]

1983 suzukimatic. Bike starts easily without the choke on and idles ok for a few minutes, occassionally a very high idle. once it is warmed up, then it wants to die and not restart til cool again. Charging system is normal, good gas in it, nothing leaking, not smoking. tried draining the carbs already and cleaning the filter. will be changing coils soon and found a newer ignitor. no way to adjust carbs so not sure where to go from here. has new plugs but after running it and pulling new plugs the plugs r blackend slightly and is usually a sign of weak ignition or fuel mixture, if i am correct? Any ideas or anyone experienced this issue as well?

Hi,

Are there leaks in your air intake system? This includes the airbox, intake boots, and O-rings. Are you using an inline fuel filter?


Thank you for your indulgence,
