For future reference the carb kit for the 78-79 XS400 contains the correct needle jet. The box and most vendors will tell you otherwise, but I received in the mail yesterday and it's a perfect match. Please visit siriusconinc.com for parts like this. They were very helpful and pleasant to deal with.

Thanks guys. Unfortunately the Keyster kit for the 77 doesn't come with the needle holder. The '78-79 kit does but I don't know what size it is. I will try to call someone to find out. Motorcyclecarbs.com has a great selection, but not my size. Any additional suggestions are welcome....thanks.

I am struggling to find new needle jets for my 77 XS400. Yamaha part number 2A2-14941-04-00. PO really messed them up. I tried Mikesxs thinking that Mikuni parts were interchangeable but they are not. Any help would be greatly appreciated. Right now this is the only thing keeping me from rebuilding the carbs. Jay
