Trike, left me stranded for a short spell, had to trailer her to the dealership after the starter motor engaged while riding.
didnt have a clue until i got that "smell" when i stoped the smoke was pretty bad and i thought the bike might go up.
i have pretty loud pipes so i did not hear any engagment of the motor.
I noticed the staRTER ENGAGING BY ITSELF LAST YEAR AND TOOK IT TO THE DEAlER. THEY SAID IT WAS THE STARTER SWITCH AND THAT WAS REPLAced. looks like the problem might be that again or something deeper.
