My 2017 TG is now at the dealer with the top end removed from the engine. Lost oil pressure last week while out on a short ride. They are replacing the oil pan, oil pump, lifters, pushrods, cylinders and pistons. Pistons were pretty scarred and everything had that burnt look. They said that this is only the second stock 107 that they have seen with a sumping issue and both have been trikes. I have almost 49k on it. I looked into paying the difference to do an engine upgrade, but have decided to ride it to the end of the season and trade for a new one. Really glad my wife talked me into the extended warranty, which ends in January.
