Dragon falling on its face???

[goat]

I have a 08 Dragon with the fix kit in about 300 miles on the new motor it ran strong til just yesterday went to take it out for quick ride and when you crack the throttle it will light for a quick second then drop rpms and run very bad evey time you hit wide open it will hit 8150 then bang done no getting it to come back. I checked valvles,fuelfilter,tps,and exhaust sensor it does not flash any codes and I have a half of tank of fuel also the pto plug is blacker then the mag side
Should I check fuel pressure
is a injector stuck or is my stator going out ?????
any help or input would be great and thanks in advance Craig

2 possibilities..pull throttle bodies, look for broken/chipped reeds, if nothing there, test the stator..paying close attention to the readings for the 2 pickup coils(but check all readings per shop manual)...thats where I would start......(this assumes that clutching is close(weights /springs for your current elevations)....and normal maintaneine has been done like fuel filters and such recently....

Might not hurt to check your TPS since AK suggested to pull it off anyway.
