I have had three issues;
1) The carbs often get clogged due to our horrible gas. This requires removing and cleaning them (3-4 hours).
2) I had a coolant leak from the hose at the back of the engine. Solved by tightening the clamp.
3) The vacuum fuel petcock assembly failed, allowing the bike to stop running. You cannot purchase a rebuild kit for the petcock, and must purchase a new complete assembly for... $165.00.
This bike looks great. I get many positive comments, from BMW, Ducati and Harley riders, as well as riders of Japanese brands.
It has more power than other "naked bikes" or "standards". The Suzuki, Triumph and Honda competition have less power and torque.
The bike is made much better with a Sargent seat, Akro carbon slip on exhaust and braided brake lines.
This is my 2nd ZRX. I owned a blue 2003 from 2003 until 2008, before I foolishly sold it for what I paid new.
The ZRX1200R is still sold in Japan with fuel injection replacing the carbs. Kawasaki was foolish to discontinue the bike in the USA..
I will not sell this bike. Mods for this winter will include OHLINS shocks, revalved forks and a light weight battery. Looking for some light weight wheels too! So far, I have shaved 21 pounds off this heavy weight, and hope to lose 20 more.
