Wanna make sure there is no major issue to be concerned with.my engine light keeps coming on intermitantly while i ride. Checked codes but nothing shows except a part number for TSM regulator which i believe is turn signal? And part number for speedometer speed gauge? Both seem fine and no other codes. There were some old codes when i bought the bike i cleared a while back but up until this long trip im on now which is longest ride its never come on except quick once or twice. Should i be concerned?
