Got my trike back from the indy shop 2wks ago and had to take it back in today. Had the motor completely rebuilt and now it's knocking again. Was going to go to Brandt's in Walbash to put some more miles on and it was knocking and had to turn around and head home. I've had it with this thing!! How much money do you put in something before you get rid of it. Either way you lose!! Jim
