@Crusty is right about the list not being major, other then the fact it stopped his trip.
The water temp sensor is interesting as I think RG had the same issue at the NORRA race. The real question is what stops the ride 1) not knowing the temp and being worried about blowing a engine 2) the ECU saying nope not gonna let you ride.
For option 1 a trail fix with a temp gauge setup from vato-zone (yeah hes in mexico, but they are not remote camping in/out of towns and i'd be they have a decent chase crew) would ease your mind.
The torn CV boot is a issue that RG and team have had, Chupacabra has had, and maybe others not reporting tot he interwebz. The wildcat XX has had a lot of boot troubles (3 generations of axles boots, two different designs), is this a trailing arm/CV design issue or boot material design issue?
Ground wire to fan, QC issue
Belt, well it's a CVT and all manufactures have had belt issues based on so many different issues, users driving habits, heat, yada yada
