P0171 must be the fuel system rail as it says “P0171 – Fuel Trim System Lean Bank 1”

I couldn’t find 171 in the official hyosung service manual,  is that what the dash actually says on the bike ?

Consider your injector system, throttle bodies in this matter here. I’m not sure how your mechanic checked that.
