PE 668 is in the shop with a heating problem. Lost all of the coolent. Would'nt restart after refill. Don't have a clue what the problem is but I have faith in my dealer, Fun Bike Center and am sure they will figure it all out. I tried to call the BEST # and all I got was a recording saying all operators are busy. This went on for about 45min. so I finally gave up and called for a tow. I feel pretty let down by the BEST service, hopefully I can get a reimbursement, but who wants to wait forever for someone to to help you especially when you've all ready paid for it. For all I know I'd still be waiting on the side of the road waiting for them to take my call. Has anyone else had any dealing with them? Right now I'm not very impressed with the service.
