Hey,
New to the group.  Just reaching out, maybe some advice.  I bought a 2018 U FOFCE 500, with 630 miles on it.  It looks brand new and runs great.  Goin through the manual, I see it already should've had it's first service.  I called local dealership, he's quoting close to 400$ as the valves will need adjustment.  Is it just the first service?  Or are they all gonna be this $$$$...seems a bit high to me.  I had planned on doin most service myself, but I ain't messing with valves.  Thanks

Valves are easy and should be at least checked twice within the first 800 miles-once will need adjustment. From then on about every 1000 miles or so. Just do it yourself...all the service work...unless there is a warranty still in effect. A service manual will be a good friend.
