So bought a used 2014 KX450f in great shape, was vet owned with less than 20hrs on it.
Full disclaimer this is my first DFI bike and I am lost in troubleshooting this issue and hope to get some others to help lead me down many rabbit holes
Symptoms:
+++++++++++++++++++++++++++++
1- Bike starts cold or hot with out issue
2- Idles for about 10 secs and then starts to hesitate/blubbers and then dies
3- Starts right back up and repeats steps 1-2
4- If I can keep it running and start to ride everything seems fine but slowing down and having to start from low idle it blubbers and pops and I have to work the clutch and get the RPM's up to keep it running
5- this all seems to happen at 1/4" or less
6- Slowly rolling the throttle on up to 1/4 throttle is where it seems to be happening. Past a 1/4" throttle it is fine. Let the idle drop down and it hesitates/blubbers and dies
7 If I can keep it running after it hesitates/blubbers it will hit hard and will be fine if I stay on the throttle
++++++++++++++++++++++++++++++
- Running Chevron 93 gas
- Air Filter is clean
- No engine mods
- PC Ti-6 Full exhaust
- Black Coupler (I have tried swapping out for the other two and same issue)
