2017 Uforce 500.  So far it's been a great machine.  400 miles on it. 
Sat for the summer at our cabin, went to run it last weekend and all hell broke loose. 
EFI light came on the dash, blinking non stop, then steady.  Then it would over heat like I never seen, even when running fast.  I had to nurse it back to the cabin.  It never over heated all the way as I would shut it down.  I noticed the fuse for the fan was blown so I replaced that, still did not work.  When I got back and got it on the trailer, I checked the air box and there was about a half quart of oil in it.  So... Needless to say, I dropped it off at the shop.  Seemed to be above my paygrade.

Sorry to hear that. May have got some rodent visitors while sitting there all summer.

Yeah that certainly happened.  Hopefully that wasnt the culprit!
