Awww come on, lay off the guy.
He probably just replaced the tach himself.
1991 and later CB750 Nighthawks use an electronic tachometer. There is no "cable" to spray cleaner or lube into since it uses wire. Problem with these model year NH tachs is a "cold solder" (bad) joint at one of the clock springs internal of the tach. To repair the tach requires cutting open the internal case. I have done this. It is not easy, but not impossible.
I recently purchased a 1995 CB750 with 33,000 miles on it. The tach is dead... it bounces now and then. Can you go into any more detail on repairing this... or replacing it? I've looked on ebay every day for two months now...
A tach is a tach. Get a cheapo replacement and be done with it.
I just bought a 1991 Nigthawk CB 750 yesterday (5/15/2008) to be used as second bike. Have same problem as others with tach. Also seems to be going faster than indicated on speedo. So far very impressed with 17 year old motorcycle. Has 19556 miles; will be using to commute 70 miles one way a week. Feel confident it can handle the task. Any more info on tach will be appreciated. Thanx Jalopy.
These are the best all around bikes ever made, but forget about the tach. The cable end wears down and you will always be replacing it. You need it about as much as the fuel gauge. Which we all know it does not have.
I have found the bike performs better if you stay out of the top end of any gear. Shift early as your owners manual states and let the engine work in its comfort zone. You will get there just as quick.
I have over 30,000 on my bike. New chain and sprocket a set of brakes, changed the oil in the spring and fall. It still runs like new.
Has anyone experimented with a larger front sprocket or smaller rear one on the Nighthawk to lower final drive RPMs as speed? This is the only complaint I have about my baby since she has no 6th gear???
I am on a old CB 750 Nighthawk 1982. The old girl never let me down, and I can honestly not say one bad comment about her; she is every bit as good as my Kawasaki GT 550. Two great bikes; look after them. and they will look after you.
I have had a 91 CB750 for about 5 months, and she runs great. Tach don't work, and it doesn't bother me at all. I have done a lot of research on trying to replace it, and replacing it will cost an arm or maybe a leg.
Anybody know how much it is to replace 2nd gear on a 750? Mine pops out at high rpm's and I've been told it's just going to get worse..
Don't replace it! The problem is not a problem with the gear, it's the shifter. The same thing happens to me when I don't mesh the gears and it's embarrassing but I live with it. Rock your toe and wriggle the second gear in place, then release the clutch slowly. It's not meant for speed shifting and it's part of the charm.
Do you recommend a CB 750 Nighthawk for a long range trip???
Pros and cons?
Great bike for long trips, I rode my 1982 Nighthawk 750 from S. Dak to Calif and never had any problems, and my brother went with me, on his which was the same bike, and he never had any problems either. The more we rode, the more we liked our bikes.
I had a Honda Shadow 700 and loved it. Ended up trading it for a Russian Command Car (Jeep) and regretted it. Now I am thinking of buying a 1992 750 Nighthawk. It is being offered for $3200 - I should add I live in Cambodia.
The bike is in good shape, but I think the price is a bit steep.
I bought my 92 Nighthawk 750 about 3 years ago for $2600, so I'd say $3200 is a little bit steep. See if you can talk them into going lower, although it depends on the miles. Mine had about 12,000 miles on it when I bought it.
I am about to buy a 1993 Nighthawk with 40K miles, needs tires, clear-coat on tank flaking, seat immaculate, front spring may be soft. This bike should go forever! I am paying only $1500, which seems to be a reasonable price for that mileage, but the engine will go 100K+ miles without rebuild when maintained. Had an '72 500/Four, sold it with 70K miles and it was running like new.
I just bought a low mileage 1995 750 Nighthawk. I've heard the engine is very reliable... How many miles can I expect it to go before any major work (such as top end overhaul) is required? I am an easy driver - will not abuse the bike in any way.
I bought a 1992 Nighthawk with 14000 miles and now have 18000. I love this bike! It does everything; long tours, 40 mile round trip commute, fun just riding around.
I put on a new rear tire and replaced my sprocket and chain last year, and I feel we are ready for many more trouble free miles! Did I mention I get 50 to 55 MPG?! What's not to love?!
Just bought a '95 750 NH about an hour ago... Took it for a spin around the block before it got dark. 37k on the clock, new tires/chain/sprockets/seat and I got it for $1450. She runs and sounds sweet in her 1st mile to get gas.
Will change oil and filters, sea foam the carbs, oil the chain, check tubage and re-tighten all the bolts tomorrow morning. Then I think I'll put a hundred or so miles on it to get acquainted. Will let you know what I think.
Oh yeah... tach's DOA.
I've had my 92 NH750 for 4+ years and it's now up to nearly 84K. In all those miles, only issues have been that the starter needed a rebuild, oil leak from valve cover gasket, and of course, the tach. Other than that, it's been tires, oil and filter change (every 3K), battery, and one chain replacement.
This bike has taken me on 300 mile day rides, around the corner to the store, and everything between. It can cruise all day at 80+, gets 40-50 mpg, is sit-upright comfortable and has never let me down.
I'd say I got my $2,000 worth. Wouldn't you?
I bought a 95 Nighthawk 750 about a year ago for $500, it had 37k miles on it so I changed the fork oil, brake fluid, oil and tires. I now have 51k on it and have changed a chain and sprocket set since. Other than a speedo light bulb and valve cover leak, it has run great. Also watch the starter switch; if it starts sticking, cable lube usually does the trick.
I acquired my black 1997 2 years ago with 8K miles on it. It now has 19K miles on it, and the only thing I have had to do is replace the rear tire, outside of normal owners maintenance. Everything works as it should and will still do 0-100 mph is about 13sec. Not that I do that often...
These bikes are very durable and are way underrated.
Even though it is now 10 years old, I still get repeated comments from people walking by on what a nice looking bike it is. The obvious replacement these days is the NT700V.
