'85-'87 XR600R KeiHin PH52
This type of KeiHin PH carbs are specific to the XR600R's listed here. All years '85-'87 are interchangeable but do differ in internal tuning. It is important to properly ID these carbs before servicing and before acquiring any parts so they run properly. These carbs are also mistaken as a "twin" carb set, when in fact they are more like a two barrel carb with a secondary. The secondary carb opens at about 1/3rd throttle so synking the two carbs to open at the same time is not something you want to do. I think they are the coolest XR carb type made.
The set pictured below is of a '86-'87 XR600R (PH52AC) Carburetors.
