looking for parts ...need on Main exterior tube the threaded air intake valve, and help please?
Suggest looking at Kawasaki parts diagram for your bike. There are plenty of these online if you Google such as at BikeBandit.com. Once you have the Kawasaki part number, Google it and search EBay. You may find it has been superseded by a new part that will fit, depending on part. You will likely find plenty of used parts cheap on EBay. Also suggest posting picture from parts diagram and part number. Many Kawasaki parts fit multiple models so it is important to find this out as for instance there may be a cheap part you are looking for listed on EBay but listed under Ninja 300 or Ninja 650. Look at their parts diagram too and compare part number to see if it is the same. Almost all Versys 650 parts also fit the Ninja 650 and ERN6, Versys 1000 parts often fit the Ninja 1000 too. You can also download Kawasaki parts diagrams in PDF format from the TECH section of this site. Just follow the links for Service Manuals.
