Great video. I really like how you explain things and work through the task. Its videos like this one that makes working on my cb650 much easier. Looking forward to seeing more from you ! Thanks again, stuart
Thanks for the comment Stuart. My bike has totally transformed since the last video of it. I have lots of video that still needs edited and uploaded from over a year ago haha. I have been busy with life and the channel has suffered. I have more Nighthawk content coming!
Loved the video man! Super helpful for my own 93 Nighthawk im working on now. I was cleaning the carbs similar to you but had a question, what are the two hoses that loop and point down for? There is one between carbs 1 & 2 and there is another one between carbs 3 & 4. You can see them in your video super clearly at 12:21. Keep wrenching!
Nice! I tuned them using info I found on the forums or in the service book. I wouldnt even know where to start explaining it. I synced them on the bench, then set them to factory spec, then got them running and did a full sync on the bike. They worked well from there.
Thx for the vid! Very helpful. Do you know the exact sizes of the screws for the bowl and top cover? Pretty much all my screws are badly rusted and need to be replaced.
I ordered a set from eBay fit perfectly www.ebay.com/itm/Honda-OEM-Carburetor-Carb-Phillips-Screw-Kit-cb1100f-cb1000-cb900-cb750-pan-head/352927691111?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
JIS screwdrivers such as Vessel are the best. Your Harbor Freight one fit well - do you know if it was JIS or American Phillips? The Impacta set from Vessel under $100 has been one of the best purchases I have made. Even the slot end screwdrivers in that set fit amazing removing carb jets, etc. I also have a 1993 NH 750 and mid carb rebuild #2 after doing it 10 years ago and putting on another 30,000 miles
Not sure if they were JIS or not. I don't think they were. Probably just being newer drivers helped. Not all worn out and rounded off! I miss my NH. I sold it a couple years ago to fund my Suburban project. I wish I still had it.
Nice video. You mentioned stripping screws when you worked on small engines. You should not use regular Philips screwdrivers on old Japanese motorcycles. They use JIS (Japanese Industrial Standard) specific shapes for Philips heads and chances are you will strip the screw heads unless you use JIS specific screwdrivers. If you don't have one, you can use the Philips screwdriver came with your bike. I learned very expensive lesson until I realized that I was using wrong screwdrivers.
This is a great tip. No pun intended. The tips of normal screw drivers never seem to bite...and that is exactly why. They arent the correct shape. Thanks for the comment!
Great point. I will go one step further and suggest replacing the JIS screws on Japanese carbs with allen screws - easily found online or many hardware stores. It will save a lot of future frustration.

How you tune this Carburetors....? I have two 1982 Honda Cb750Sc Nighthawks one with blue frame and other black frame.

I just got a pretty torn up nighthawk cb 250 and this is helping alot thanks

I would have to double check. Its been a while. I just took one screw of each and sized them at the hardware store.
@@JEGsGarage are they regular m3 screws of various lengths?

Are parts easy to find on these bikes?
Not too bad!! Getting harder though...just like everything from the 80's/90's...
Good video

from what year was this Nighthawk's carbs?
93 Nighthawk 750
Wow - they look identical to the carbs from my 83, but I suppose why would they have changed much?
