78,GL1000 dyna-s 1995 model. Coils 1978 stock piggie back resistor.(Issues) I'm going to be length in this . complete carburetor over hall, Installation, same Issues. replaced carburetors same 771A over hall, same issues. Issues as followed.
Cold start. to warm up (first warm start) Idle @ 1000 smooth,@ house no load. Bike Idle to operating temp climb, rpm tends to get erratic before thermostat open temp. Opening temp operating under no load, Bike starts to miss fire on 2 cylinders. (NO CROSS PIPE) MISSING 1ON LEFT 1ON RITE. Unsure if it is front two or rear two.
Bike fully warmed up cycled thermostat, Engine missing to stall. Restart Idle rpm floats. 1000, 950, 1100, stall.
Driving.clear weather (FROM COLD START TO OPERATING TEMP)
Acceleration from idle to 1000 to 3000 in first gear shifting to 2 gear and so on. No lag no hesitation. In 4 gear twist fully open, bike responds.
Driving. (OPERATING TEMP) clear weather.
(where things get strange) RPM climbing from 3000 to 5000. There is a moment, at start of RPM climb to 5000 where there is (slow) power acceleration. Anything above this range 5000 RPM or more seems to be operating normal. Example. Hold throttle fully open (any gear) consistent torque, In RPM range above 5000
Weather. If this bike gets WET, forget it.
All issues above are intensified 100 fold. No idle what so ever must hold throttle above 3 grand and float the clutch to take off.
RESEARCH. I read all there is to read on dyna. I have read on how to test the Ballast on the coils. I an also going to replace the dyna back to points. to eliminate the dyna pickup. I have read that there is an (intermittent) in this pickups whit heat. Also it is way cheaper for me rite now..
I feel this is not a carburetor issue, with the replacements of carburetors, I spent an extreme amount of time cleaning, checking slides for any drag. Being that this happens intermittent, I dont fell that they are the Issue. there is no sign of fuel leaking into the air chamber. they dont load up while idling. One other thing I will say. There was this one time I was riding on the hwy and got an extreme amount of fuel smell. while this was happening I twisted the throttle to full with no response. pulled over it died . restarted it ran fine , (with listed issues above).
SOMETHING NEW. BUT NOT ALL THE TIME
Now when I ride this bike Bike fully warmed up cycled thermostat, Engine missing to stall. continue throttle twist (like pumping the gas to clear or keep it running. Only from take off then listed Issues above.
I hope this is plenty to go on. I've had this bike awhile. I enjoy it, it hasent left me stranded. I'm confident in my ability's to work on it. I'm good at what I do. BUT this leads me into a direction that I am brain locked. Being that I've spent so much time in the fuel delivery, an not so much on the electrical. I've also read these bikes can be tricky when it comes to the electrical. So I feel that by going back to the beginning of what was firing this bike. that would be the safest bet. IE-default mode. my user name is my email @gmail if you would like to send me one and have a chat on the phone. I wish my dad was here to help me but he is not.. This bike is my only out to a means of happyness with my life, with my wife. My to favorite loves in life. ANY comments or a email would be cool if you dont mind going over something like this.. thanks so much..
