Can anyone point me in the right direction to get a 1986 Honda CB450sc Nighthawks carburetor rebuild kit? I am not sure how to use this forum yet but would like any help in this

I recommend using the Honda OEM gasket set. Float needles and air cut valves both need to be Honda OEM not aftermarket. While you're doing this I'd suggest replacing the insulators at the same time. That way everything that can fail on the fuel side has been refreshed or new. Here's a couple of dealers that offer discounted pricing.

There's a sticky in this section on rebuilding these carb that will help you.

Yeah you wrote sticky and was looking at partzilla and hondapartshouse for the air cut off and the accelerator pump, said unavailable. I will check your sites tomorrow the diaphragm were in poor shape the accelerator crumbled..

Accelerator pump can be aftermarket.
Might verify the carb numbers you have, could be earlier versions using different parts.

On my Venture carb rebuild I used K&L parts. I have used another place for rebuilding my carbs for the hardware and software I believe in Netherlands. Not 100% on that but you have to know what carbs you are working on. Where do I locate numbers of carburetor? Is it on the the slide covers? I want to say it says kein something..

Thanks now I wished Yamaha had the gasket set available for Tinker. I ended up going mostly aftermarket for her. I like using OEM whenever possible.
