This chart represents the models using TK21 or TK22 manual-slide carbs. (known as "TK" brand outside of Japan). All used the same pilot jets. KZ550. models also had caps covering the air screws to prevent users from adjusting the air screws. However. made in subsequent years. Later models with CV type carbs are not represented here.

The TK-22 carbs are a mechanical-slide carb with a single main jet and a single pilot jet. the 1983 KZ550A4 uses different carbs than the 1980 KZ550A1. models use the non-adjustable needle which is exactly the same as the adjustable needle set at the second clip from the top. All variations of those carbs are the same with the exception of the main jet. The same bikes. and internal dimensions.

They were used on early Kawasaki KZ500. and will be under construction for some time. needle dimensions. with the exception of the main jet on the KZ550 D1. but some of it will apply to TK-21 carbs as well. but the KZ550D carbs were painted black. because they also use the TK22 carbs. maybe for racing. using the same carbs most likely have the same internal setups.2 di 6 This page was started in June of 2011. Most TK-22 carbs came in silver. the 1981 KZ550C2 and 1982 KZ550C3 would have the same setup as the 1980 KZ550C1. For example. and KZ400J (inline-four) motorcycles. 30/07/2015 00:02 . so its setup would have to be different. but some were not adjustable). but all of the KZ400.
