[Nighthawk Lovers] Re: 80's NH Brake feel

[Dustin Anderson]

Also, make sure you start with the caliper on caliper on the opposite side 
of the master cylinder, then the other. I heard you could wrap a rag around 
the lever and the grip and zip tie it after bleeding the brake lines which 
also helps with brake response.

I got no idea dude, but I think that mid 80's dual disc brakes are just 
that way.

[Nighthawk Lovers] Re: Questions about engine heat.

[Dustin Anderson]

I let it cool down and then started it and did the big horrible of revving 
it, then shut it off and then tried to start it again and it cranked like 
it used to before it waited for parts. Starter motor and clutch was 
supposedly replaced before I bought it, which doesn't rule it out as being 
the problem but thanks for the focus.

The "alternator" on them sucks. Below a certain RPM the electrical
load is still net negative. If you've let it sit for a while, and then
only take it on short rides, or slow rides... sounds like an empty
battery.

Easy to diagnose, jump it from your car when you know it has trouble
starting. If it immediately fixes the problem, the problem is your
battery is either drained, or, because it spent too much time drained,
permanently weak and needs replacing.

If it's not that, then I have no clue. Actual engines are black magic to me.

Re: [Nighthawk Lovers] Questions about engine heat.

[Javier Garcia]

I agree with Graham, that sounds more like a classical problem with the
starter motor. When hot loose power. Usually a simple rebuild will fix the
problem. My general advise to any owner of a cb700 is to be particularly
careful with the starting system, because if the starter clutch goes bad,
it becomes a very serious issue. It's located at the bottom of the engine,
and replacement requires a complete tear-down.

Javier.

[Nighthawk Lovers] Questions about engine heat.

[Dustin Anderson]

I recently replaced the spark plugs, exhaust gaskets, rebuilt the clutch 
slave, replaced the gear shifter cover gasket, gear shifter linkage seal, 
oil pan gasket and the gear indicator seal. No leaks as of right now, but 
the motor is having problems turning over after a short ride, due to the 
engine being hot. I also noticed that the valve cover on the front, above 
the headers is starting to leak and that the engine seems to be hotter. The 
CB700 seems to be running better than it did before, but when I stop it 
seems to be wanting to not turn over. My question is how does one know if 
the exhaust gaskets are sealing properly? Is it just my two year mark on 
the battery and time to replace it?

Welcome to the group. The 82 750 should have 2 pipes on each side so that
appears to be aftermarket. Otherwise is looks pretty clean from what I can
tell in that pic.

[Nighthawk Lovers] New Owner

[Roger Vallve]

I just picked up a 1982 Honda Nighthawk 750, I live in Hamilton, Ontario. I 
attached the pic from kijiji ad.
The purchase is a bit of a nightmare so far. First the buyer and I lost the 
keys when we moved it with u haul trailer. Getting it rekeyed.
Now the buyer can't find the right side of owners permit for transfer of 
bike. He is working on getting a new permit, so he says.
It gets better, I broke my thumb fixing my other bike! Can't ride yet.
That is 3 so I am hoping things improve from here on.
The bike has one exhaust, I don't see any name on it. Is it aftermarket or 
original?
Pictures pending
Plan:
-Repaint motor
-touch up paint on gas tank and a few other bits
-change oil
-change oil filter
-change air filter
-clean it all up.
-tighten all bolts etc

Long Tern Plan:
-add engine guard
-new grips
-new handle bar maybe
-upgrade dash lighting to LED
-upgrade headlight
-rebuild carbs
