-2004 Sx200txrc with 485 hours
-compression 125 on all cyl +/- 3#
-fuel pressure 37#
-sparks tests out to 10kv and does not drop spark
-only no ethanol
-new fuel lines, bulb, LP pumps, all filters including tank filter, injectors, HP pump, fuel regulator, O2 Sensor, tps and cranckshaft position sender, water temp sensor, plugs
-all in spec: ECU, Trigger, Pulser, Charge coil, coils, vacuum lines and fuel lines, no open grounds and engine is properly grounded.
Motor will start right up and idle at 1100 RPM for 30 seconds, drops to 500 and stubles then stalls, will start right back up.
TPS set at .50 and synched throttles (all work done to Yamaha Factory Service Manual provided by SIM)
tested Crankshaft Position Sensor voltage at green white, green blue connector and was getting 15-18v, spec is 6v. Also if i disconnect this coupler the idle comes up to 17-1900 rpm and engine idle flawlessly. This is very puzzling to me. Im usually pretty good with finding gremlins in a targetted, planned out manner if trouble shooting but I dont know where go now. The reason I swapped out the any components is because of the specs were off per the manual, not scattergunning but they remain unchanged with new oem parts. Im baffled...
