Wow..thats nuts, and pretty poor service from Kawasaki, themselves. I know its not the dealers fault. Im with you, too , in not going after the shop.
I know you are that 1 in a million case, with regards to mileage, but I'll imagine they were happy to take your money when you bought the warranty?
Right after the 2011 blew up (that g4 blew at 50,000 miles no extended warranty) we had to take a few months to move about 100 miles. When settled in new place, first thing I did was call this shop for a new g4. No return call. So I just called one of the shops in SF area and they delivered the '13 AND delivered the blown '11 at yet another shop.
I knew that my new dealer, near Laguna, interestingly, was kinda slow.
And I bought the extended from here; Contact - D & H CYCLE
So didn't buy the bike or warranty from this dealer BUT this dealer did do warranty work on the cam last year so the shop has had the bike twice now.
Slight topic change, but before I forget to report this observation, based upon two blown g4's, both bikes went through about a 4 to 6 week period, right before failure, of pure, sweet, powerful, smoothness. Indeed, about one week before the '13 failure, I thought at least twice during the loop that the bike was in 'that dreaded smooth but beautiful-zen mode and hope it doesn't blow up.'
Something sweet comes together on the g4 right before failure...bitter-sweet, g4 style.
