Carburetor on yamaha xj700 maxim x

Actually, they're not Hitachi carbs. Since you have a 1985 "Maxim-X", the model number is actually XJ700XN. The XJ700 does indeed have Hitachi carbs but your bike, the XJ700XN Maxim-X has BS33 Mikuni carbs.

Careful with the model number, the XJ700 and the XJ700X are entirely different bikes.

By the way, if you want more answers about your Maxim-X, feel free to visit the "Maximum Maxim-X" web site at www.maxim-x.com and the lesser known FTP site for the Maximum Maxim-X web site at www.maxim-x.com/pix
