      I did have to adjust the air screws in quite a bit. I believe these carbs are jetted quite a bit on the rich side.

    I am building the same bike right now, and am tempted to go with these instead of rebuilding and jetting the old carburators. I see you rebuilt your originals, why did you go with these? How long did it take you to get them? Were they pretty much plug and play tuning?

    • @ncv4708

    is it possible to install one of these without moving 5o battery location on my 2000 cb750 nighthawk? it says on murrays carbs that you dont have to do any frame mods, but it seems having the relocate the battery is a pretty big task

    • @ncv4708
      @ncv4708  10 месяцев назад +1

      Unfortunately since the airbox is also the battery box (molded as one piece) I think you have to relocate the battery or hack the battery/airbox down to fit the carbs.

    Hey there, nice video! I am new to the motorcycle community and I don't have a lot of knowledge about carbs. I have a 1993 Honda CB750 and was wondering about this kits' amount of carbs. I assume the 1992 version also has 4 carbs. Could you explain if there is any difference in performance with using 2 instead of 4? Do each of the carbs you installed in this provide the same amount of fuel/air as two of the stock? Thanks for the help!

    • @ncv4708
      @ncv4708  8 месяцев назад +1

      So this kit has better performance, but uses more fuel. The factory carburetors function off vacuum (CV style) which meters fuel differently than the Mikunis which are a slide style that is directly connected to the throttle.
      The bike can actually burnout or wheelie now with the new carbs.

    How come you decided to replace the original carburetor after putting cone filter on? Ty

    • @ncv4708
      @ncv4708  Год назад +1

      So CV carburetors do not function very well without the airbox. When the airbox is removed the vacuum pulses are disturbed and they will bog amongst other issues. So to make sure the bike would run 100% it was decided to go with traditional style carburetors.

    How did you delete the stock air box? On the CB650 I’m working on, the box is connected to the rear fender.

    • @ncv4708
      @ncv4708  Год назад

      This one was pretty similar. Since the rear frame was cut and a new hoop / fender and battery box was added it basically deleted itself. This ultimately led to changing to the Murray's Carbs as the stock CV type carbs do not like to run without the airbox.

      The bike actually didn't run when I received it. Also since we were removing the airbox this seemed like the only option. However compared to bikes with CV carbs I've ridden, the Mikunis have MUCH better throttle response, it's zero lag.

    I just picked up a 1982 Yamaha XJ650 Maxim and ik they are completely different but I have a quick question! Did doing the 4 carb conversion to 2 change anything of the bike? the sound or anything at all? They offer the conversion for my Yamaha to and want to know before I order!

    • @ncv4708
      @ncv4708  5 месяцев назад

      It didn't really change the sound, but it did make the bike rev quicker and actually make it capable of picking up the front tire since it got rid of the lag of the CV style carburetors.
