    Check these SS 4 to 1 headers out, and from real exhaust engineers (a black art). The only thing would be to get them from another Euro country except UK since 100% tax anything shipped. I found a couple more SS alternatives, but these guys may be able to stamp db limits on the pipes that would satisfy CA EPA stamp requirement. UK really has some nice job shop vendors, but the 100% UK tax man (to USA ONLY) can bite my #$%&.
    :clap

    And look at these dudes (from where else, UK) 4 into 1 (50% more cost) and look at the FLAT 4 into 1 transition for maximum vertical (speed bump) ground clearance. BUT they are chromed and not Grade 304 (!) SS, boo!

    Life is looking better, but I want the 20 year plus SS exhaust. That cleaning chrome exhaust pipes is for the birds, especially when rain comes down upswept pipes and I can't cover hot pipes with my cover. I was spoiled with BMW F650 ST which had SS no maintenance pipes. Chromed (only) pipes is a mob racket (CA DMV and OEM dealers)!

    Nighthawk S Forks Air Valve Issue


    Hello all,

    My name is Jimmy I'm 31 and from NYC. I picked up this NHS this past Christmas and am just getting her ready for the road. For some odd reason, the previous owner had a schrader valve extension of sorts on the air forks valve near the handlebars. I spanned off one of these extensions and have no air in my left fork now. I tried loosening the nut thinking i could slap on a standard Schrader valve, but the nut won't budge. I've tried WD40, liquid wrench, and a breaker bar. I'd like to pick your brains before I brute force this thing off.

    Another idea i had was to just replace the valve core on the left side, but this would still leave that extension on the right fork.

    Anyone ever seen anything like this before? Pics to follow

    Unfortunately my phone died so I couldn’t take a pic of mine, I will upload tomorrow, but just for reference, this is what is has instead.

    Anyone ever seen this on a bike, or have any ideas? I really want to get her on the road already. Any thoughts or ideas are greatly appreciated. Thank you in advance.

    Does this just screw into the top of the fork? One on each side?

    I don't think I'm any help but it appears that Bike Bandit might show this but state it's unable to ship.

    They're calling it a bolt assembly and their diagram is horrid but it looks like it could be the whole assembly, I don't see any valve stems but I was also guessing on the year and just picked 1984.

    Retail shows at $60 each, have you checked with the local Honda dealer?

    At 242 Pages, perhaps the mods can allow for a NEW "Official Nighthawk Thread -- 2013+" ? Having said that, there seems to be a trend with super long threads here. :D

    Looking to install a set of heated grips on my '98. Is there a preferred circuit to pull the power off of, or do most of you who have heated grips run them off of a dedicated circuit?

    For example, on my WR250R, I used the headlight circuit as it has 15amp capacity and uses about half that, leaving plenty of overhead for the grips.

    Also, any recommended front brake pads? The originals are getting pretty thin. OE? EBC?

    I would run a dedicated fused circuit off the battery with a relay run from a switched circuit. I ran a relay for a power input off the taillight circuit which is accessible under the seat. You can check out a thread here (Lots of great help and info available at nighthawk-forums.com). For the brakes, most use OEM, but I've heard the EBCs are good too.

    On a thump with constant vibration, heated grips are needed therapeutically. But on the NH 750 because it is so much smoother, it would fall way down the priority list of additions in So Cal, anyway. ymmv

    My WR is just about as smooth as the Nighthawk, so no therapy needed there. And I live in Alaska, not the people's republic of Kalifornistan, so heated grips are a very nice thing to have.

    Heated grips are nice thing to have here in Canada as well, as they extend the riding season! My last ride, a BMW K1200RS, had both a heated seat and grips, and I felt really pampered. I might add heated grips to my NH towards the end of the season.

    I stand corrected and can see how that would bump heated grips up in the priorities.

    At least you are not in a state with 45% of US population and everywhere is like a parking lot every which way you turn. Compared to the Appalachians, the roads are not that hot with constant road work as well.

    It also has about 45% of USA manufacturing which I will get back into as a consulting job eventually. Coming from FL last, its a blessing! :rofl

    Has anyone replaced the head bearings on their NH with tapered bearings? I might want to do that--wanted to see if there are any tips, things to look out for, as I do.

    Just did my 650, no problems.

    Used a chisel to ease off the lower race from the steering stem.
    Bought a section of 1/2 threaded rod and some washers/ nuts to press in the new races into the head. worked fine. Use the old races as padding. A piece of PVC pipe that I had laying around was used to put the new race on the stem. removing and replacing all of the gear at the front of the bike is the biggest nuisance.

    'Spleen--
    I did my 650 three years ago, when I first got it. It was a sorry mess, so I replaced all the replace-ables.
    I tend to over-think things and worry about how things go together, so putting in the tapered head bearings was probably more of a job as a result.
    But it was straightforward, as I recall. Some confusion about which side is up, but the folks on the nighthawk forum got me squared away. A question about spacers was answered there too.
    All in all nothing too challenging, once my brain got out of the way.
    I hadn't ridden the bike with the old bearings, but they looked :puke1. Bike rides quite well now; a few long trips and another in May on those bearings.
    Good luck.

    I checked out my octane rating in Clymers at 86, and that is Mobil regular (Mobil runs the best with me historically, mileage and performance any kind of vehicle).

    I had always heard, premium, regular, ... It is just octane!

    On regular, it fires so much stronger and easier. Plus, it is cheaper too! :rofl

    I really hate putting gas in though holding those stupid vapor lock springs back. I need to sue them for carpal tunnel :-(

    Looks like a great day for riding. Nice photos.

    Instead of riding this afternoon I thought I'd put on the new rear tire on the '82 450 I bought a few weeks ago.

    This bike is new to me with under 9,000mi on the clock. I've ridden it just about a hundred miles so far. Mostly at speeds under 45mph. I put a new front tire on last week, the DOT code was 406. That's 1996, right? This was the first motorcycle tire I've ever changed but it went fairly smoothly. The guy on the Youtube video did it in 12 minutes but it took me all afternoon. :)
    So today I started to put the new rear tire on, code was 384. The axle took a little pounding to drive out but not too bad. Since I've never taken a rear wheel off a motorcycle I wasn't exactly sure what to expect. But I'm pretty sure it shouldn't have been this:

    There aren't supposed to be jagged bits of metal in there are there?

    Or those half bearings outside the race?

    I'm about to read up on bearings in Clymer. Any other thoughts? Suggestions?

    Looks like your outer bearing exploded. Your outer bearing is supposed to look just like the one shown on the wheel hub in your picture. Not too big of a deal to replace. You may need a bearing puller to get the old mess out. Might as well do a few others bearings while you're at it...

    Hey folks! It's been forever since I posted something here I am ashamed to say. My '03 Nighthawk 750 has/had a Memphis Shades Bladerunner Windshield in gradient black on it. I've been teaching my son to ride (don't think little kid, he's 31, 6'6" and 270#'s, think hulk). Anywho, he dropped it and broke the windshield. Motorcycle Superstore had one just like it for $59.95 when he broke it. Should have ordered it then. Now, the only place I can find one is fleabay and the seller wants $87 for a clear one. Any of you all know where I could find one in gradient black (or gradient red) for a reasonable price?
