what would you guys say the life expectancy of a 93 zx-6 is as long as you change the oil on time and dont beat it up, mostly drive highway miles?

 

any engine can be rebuilt, any part can be replaced. bikes can last forever if you have care for them.
boring and honing, oversized pistons. amen.

 

It all depends on how you ride and the conditions you ride in. If the area is dusty or sandy, then you'll have to rebuild sooner. I'd say you can get atleast 50K plus before you need rings or a rebuild. Start using Synthetic oil and it may last a lot longer.
