1982 Nighthawk 450

I found an '82 for $600 with 5550 miles. It sat for 6 years. The owner drained the gas and kept it in his garage. I blew out the mouse feces and emptied the broken bird seeds from the air filter. Changed the oil. Removed the tank, checked and blew out the petcock. Yes, I got a fresh air filter and battery. Amazing, with the low miles, it doesn't show much wear. The brakes are excellent. The original tires don't have any cracks. I added some gas and the carbs are leaking. Next week I'll put on my surgical gloves and waders and go after the carbs.
This Honda twin is part of the not so heavy crowd. As a standard bike it has an upright riding position. I may fiddle with some different bars, but I have a ways to go before that happens. I like Yamaha Radian bars.
Squirellman, any advice on these carbs?
Cheers,
Bill

Nice find. Hopefully there won't be any horrors involved in getting it back on the road.

Thanks, Keith. I hope everything is 'true' in there. That's why I had the engine turned over just to be sure the worst wasn't hiding.
As a ex BSA OC guy, a 400 lb or so twin is stuck in me. This Honda has Royal Star type power, but with a ton less shaking.
Tomorrow, I'll start on the carbs.
Cheers,
Bill

Get new tires for it. Even if the tires were new when the bike was stored, they should be replaced. If they're older, you would definitely want new rubber. Even though they look good, they can be dry rotted and/or the integrity of the carcass can be suspect. You're going to be riding this bike on the road, in traffic. Do you really want to experience a tire failure in that environment? Spend a little bit of money on new tires for some peace of mind. I cannot imagine they would cost more than $150, for both.

YUP, pick up a set of Kenda Challengers. Great inexpensive tire.

I'll be replacing the tires, absolutely. Carb work first. It's just kind of cute to see those tires, like a Honda time machine in 1982.
I noticed the swing arm bushing has grease gun fittings on both ends. I'll have to get someone to push some grease in there.
It ain't a V, but it's a neat bike. One I can 'zip around' on.

Nice find, Bill !! And a sweet little bike. Carb leaks could easily be from shrunken bowl gaskets, so you just keep fuel in carbs for a day, and they swell back to original size and no more leaks. If fuel emerges from overflow tubes or from air vent tubes, you have leaky float needles that may be fixed with a little cleaning.

Wow. I better start doing PMs to you whenever I go after carbs. They are off the bike and on my workbench. I'll re connect them and see where the leaks are and go from there. The rebuild kits are not cheap at the dealer. I thought it was cool that the Honda OEM is available.
I'll pair them up again. Connect a gas line and see where they are leaking.
I may put this off for this week. I'm prepping for a video shoot for a possible ride this weekend…. if it isn't raining.

If you can get a rebuild kit from the dealer, you can, most likely, buy it on-line at a greatly reduced price.

I've slowed down, working on a video. When I get the carb apart we'll see. If I'm lucky I'll get away with needles, gaskets and the O rings on the pipes.
