Engine blown out
About a month ago my engine blew out. I went on a longer ride on a hotter day and my engine locked up.
I took it to the dealer and they said that the head gasket was blown and it had low oil. Since it is under a year old, they called Kawasaki. Because the oil was low they'll only pay for a portion of the repair. They said most likely the parts. The oil light indicator never came on, but I should have still checked it before I went on a longer ride that day.
They said they are going to need to rebuild the engine. They are going to give me a itemized list of what needs to be done, but over the phone they said ballpark $3k.
1. Is it worth rebuilding the engine, or should I get a new one? If I can even get a new one. Could there be issues with rebuilt engines?
2. What other engines would fit the z650 frame? If I wanted to put a different engine, would the frame have to be modified?
