    '79 1000S carb help

    I'm restoring a 1000S & have installed a Vance & Hines 4 into 1 exhaust. Considering a carb upgrade rather than just re-jet. Any advice/experience would be greatly appreciated. Certainly willing to invest in a great set of carbs. TIA

    VM29 "smoothbores" are the period correct mod. Figure on spending about $700 for a nice set after all is said and done. Get some real K&N pods too. Or maybe those sold by APE. Jetting is always an adventure, but there should be some people that can help in that regards. I think there are newer carbs as well, RS34's maybe, but I'm not overly familiar with them and will defer to others for those recommendations.

      Mikuni VM29 smooth bores would be very proper.

            Hope not, since his carb jobs get bashed regularly.

              If it is, stay very far away. He did a set for me that was terrible. They were never right and as I learned more I realized all the pilot fuel seats were quite damaged. I ended up trashing all four carburetor bodies. I paid good money for the job, sent him a good set of core carburetors and got back trash. It was a very expensive lesson in how to rebuild my own carburetors. He should stick with his Harley.

                I saw the set on fleabay & didn't think they were priced to sell. Certainly appreciate the guidance & will begin looking into a set for appropriate $. May investigate a new set right from SUDCO.

                  Another question, if I do go with VM29s will the stock carb boots mounted to the head still work?

                    Yes, if your boots are flexible enough

                    The KZ boots are better, but $$$$$

                      Boots are brand new so I hope they'll be fine. Thanks for the guidance.
