Product Details


Bob's Service Kits are made to take the hassle and guesswork out of buying maintenance parts. Now, instead of searching through pages of microfiche, you'll get everything you need – the RIGHT stuff – with just a couple of clicks!

This “Deluxe” Carburetor Rebuild Kit is for all 1977 and later Airheads equipped with 40mm Bing CV (Constant Velocity) type carbs.
Specifically, this kit fits...
All 1977-1984 R100S/CS/RS/RT models, plus some of the basic 1979-'80 R100 & R100T models equipped with 40mm carbs.

NOTE: If you have an R100 model and are not SURE whether your bike has 32mm or 40mm carbs, you can look at the factory stamping on the carb body just below the dome to find out. In a series of of numbers separated into three groups by slashes, the middle group will either be 32 or 40.

BMW has traditionally offered a Carb Kit that provides routine replacement seals and gaskets. However, the technicians at Bob’s, who have restored and rebuilt countless Airheads, have found that several other critical carburetor parts typically wear or deteriorate to a point of affecting performance as well. Thus, our Deluxe Kit, developed through years of experience, comes with everything a thorough carb rebuild should have.

This KIT contains:
• 1 Gasket Kit for Bing CV Type – supplies both carbs
• 2 Carb Diaphragms
• 2 Floats
• 2 Float Pivot Pins
• 2 Float Needles
• 2 Float Needle Retainer Clips
• 4 Throttle Butterfly Shaft Screws
• 2 Vacuum Screws
• 2 Vacuum Screw Gaskets
• 4 Carb Top Screws
• 2 Throttle Return Springs
• 2 Choke Return Springs
• 2 Carb to Head and Air Tube Rubber Sleeves
All parts are Genuine BMW Parts.

Complete carb service also requires thorough cleaning. You need a high quality can of aerosol Carb/Throttle Body Cleaner on hand to flush jets and nozzles and generally clean out the dirt and gunk and use of the jet cleaning tool.
