Update: another trip today but in the rain. no error. real test may be in a couple hours when I head back home after the bike has been parked wet.
Sorry to hear you are still having issues.Error 1027A last week, no motor power, did not recover after battery reseats. Let it sit overnight and it was fine. Last friday, heavy motor vibrations randomly while cursing at top speed. Same this morning. Requesting a refund after 5 repairs and a new bike swap.
