I have a 08 Kawasaki Kfx450r and have tried everything I can think of, tps is set to .64, valves are good, changed fuel filter, checked all the fuses and tip over sensor and changed spark plug and coil.It seems to have good fuel spray from the injector.It’ll fire but not completely starting. Started up fine before I changed the filter but would start bogging so I changed it. Not sure what it could be. Any help would be appreciated.

Only with the Procom ECU can you set the TPS @ 0.64 dcv

Stock ECU the TPS range is 0.58~0.62 DCV @ Idle & 3.7~4.4v @ WOT

Check your Valve clearance to be in range..?
