We have seen the gradual migration of the K-37 to the K-37A and then the K-38. The K-301 went through several iterations

In actuality, the prices are listed to In actuality, the prices are listed to merely give you a hint a how much it merely give you a hint a how much it

might cost!might cost!

I would strongly suggest giving your favorite local Ural dealer a call for a price on a Keihin L22A.

ObservationsObservations•Most Carburetors Sold in Pairs•Certain Carburetors Are Side-Specific–Mixture Control Always Remains on Outside•K-37/K-37A/PZ-28D, K-301/K-302, Kaptex VDC-RAM (Ukrainian Copy of Pekar K-68), K-68

•Replica Carburetors (Chinese Knock-Offs) Cost Less–Pekar K-65: 89€ pair, Chinese K-65: 59€ pair–Pekar K-68: 131€ pair, Copy of K-68: 70€ pair

•As the Age Increases, Availability Decreases–Many Carbs Have Been Replaced with Better Performing Devices•K-62/K-63/K-65/K-68 Replaced the K-301/K-302•Jikov 2928CE Fitted on 1998-to-2000 Urals Exported to United Kingdom (650cc) to Replace Dreadful K-301•Mikuni VM-28 Replaced K-68 in 1998 to Meet U.S. EPA Requirements

–Most Russian Carburetors Are No Longer Produced•K-37/PZ-28D, K-301/K-302, K-62/K-63, Jikov 2928CE, Kaptex VDC-RAM (Ukrainian

Copy of Pekar K-68), Mikuni VM-28 •Many of the Carburetors Were Limited in Production and Thus Not Widely Available Today•K-62/K-63, Jikov 2928CE, Kaptex VDC-RAM, Mikuni VM-28

–Current Carburetors (Keihin) Have Been Used for Several Years and Thus Will Be Available Even After Production Ceases•Ural Introduced Keihin L22A (CVK32) in 2000

• Individual Carburetor Components and Repair / Re-Build Kits Are Readily Available over the Internet–See Ural (Урал) - Dnepr (Днепр) Russian Motorcycle Part 14: Carburetor Repair / Re-Build Kits
