Rob's Carburetor Rebuilds

'90-'93 ZR550 Zephyr with Keihin CVK Carbs

This is the ZR550 Zephyr with CVK Keihin four cylinder carbs.  All the years listed will interchange physically so sometimes the wrong set can be installed. Although I always recommend installing the proper set, as long as you match the parts to the ID on the set you are typically fine.

Sorry, no pictures of this model. They are the smallest of the US CVK Keihin carbs and have the same size bodies as a EX250 Ninja.  All models and years listed here will physically interchange, but the different ID numbers do not have the same internal tuning.
