I'm sorry to hear that, Fuzz. Other than stuff I've added to my 2014 to farkle it out (electronic cruise control, Ergo III's, ------- windshield, linear actuators to make said ------- electrically adjustable) the only thing I've had to do is ride mine and change the oil/tires. I DID have to visit the dealer just before my 5 year anniversary of buying it...to pick up a container of coolant to top it off.

In fairness, I did help a buddy swap out the rear diff on his F6b due to a leak, so it's not unheard of...just rare. Good thing they're available from trike shops for about $100 brand new. Give the old gal some time...hopefully you'll see that she's more reliable than you've seen so far.
