I have a 2007 Zx14 that I bought brand new. On start up the bike sounds like someone put all their loose bolts in my crankcase since day one. I had to replace the motor at just around 10 miles. Now that replacement has thrown a rod threw my case again. I’m not putting a third engine in this piece of crap. I’d suggest y’all get what you can for these pieces of shit while you can. I’ll never buy Kawasaki again!
