Hawk250dlx fuel?air?spark? Problem

PeteTheCat · Yesterday, 01:45 PM

hey guys i’ve been having a battle with my 2022 hawk DLX the past 2-3 months. i can’t seem to get it running properly.

bike turns on and has a rough low idle. when given gas it either dies or bogs
(when is dies smoke comes out exhaust)

i’ve tried many different things and have replaced over $400+ worth of oem parts.

REPLACED:
air filter
fuel pump & assembly
throttle body
spark plug

TRIED:
compression test (155psi)
different gasolines/ additives
spark test(plenty of spark)
fuel pressure test(in spec)
pulled out the injector and it’s spraying fine.

The problem originally started when i was riding and it started sputtering/losing power so i took it home.

Anyone else have this problem? any solutions? i’m thinking it could possibly be ECU or piston sensor but i replaced piston position sensor about 700 miles ago.

any help is appreciated

Have you scrutinized your wiring harness for loose connections or exposed wire? How about the vacuum system. I would think you would show a check engine light if one of the sensors was bad. Have you adjusted the valves?
