This is a rebuild kit for the BG Barry Grant and Demon 850  including the Speed Demon, Mighty Demon and Race Demon. This kit also fits the 825 Demon as well as all of the Race Demon RS carburetors that have a 1 3/4 butterfly in them.

This kit does not come with a power valve.   Both the metering block and fuel bowl gaskets are the new black coated reusable ones. An extra set of paper needle and seat gaskets are included for float adjustments and these kits are now shipping with v iton mixture screw orings and a loose pair of v iton needle and seat orings .

 

Please note: Be careful of other vendors generically classifying their rebuild kits as being for the 850 Demon as many of them do not have the correct inlet fitting gaskets. Our kit also comes with the o-rings for the sight glasses that use the clip for a retainer and the older screw in ones.This kit is only for the 850 and will not work on the 750 but we do have those in another listing in our store. We also offer this kit without a power valve as well.

  Please note that the metering block and bowl gaskets are a true coated gasket that start out as a standard paper one and then gets a protective coating on it to be compatible with modern fuels unlike the cheaper imported gaskets being sold claiming to be coated. The last picture shows the difference between our coated gasket on the left and the imported "coated" gasket on the right which is not and just a thick paper gasket.


These parts are manufactured by Walker Products which was one of the original Barry Grant / Demon vendors that was used prior to 2011 and the same components that your carburetor would have been originally built with when new. Kits are assembled by us in house.

Be sure and check our store for more carburetor and fuel systems service parts. We have been providing tech and working with the modular style carburetors since the early 90's.
