Is your seatbelt on?
if all else fails try a couple ounces of SeaFoam, i used this stuff on my boat motor for yrs and it really helped the fuel system out.have you checked the spark arrestor, if its carboned up it may require removeing it and a thourough cleaning.
Most likely the injector harness. OTBPOWERSPORTS.COM for replacements.The check engine light came on and it's giving 651 error code, which is an injector issue. At least now I have a place to start diagnosing. Thank yall for the help
