maintenance

Hi, I wonder if anyone on the forum can help on this one. The main cam chain tensioner for the crank to cam chain on my 1980 DOHC CB750 F has broken, reading the work shop manual it seems to say you can remove the tensioner without taking the head annd barrels off, can anyone help, how much of...

I've got a leak in the front left corner of my gas tank. I need to take it to a shop to have it patched but first I need to completely drain the tank. I've already drained most of the gas from the tank from the petcock. There still remains a small amount of gas/water in the tank. When I roll it...

Hey everyone, I'm out on Long Island, NY and I was wondering if anyone on here knows of a shop or person that works on CB's?:thumbsup:

Hey people, I'm re posting these links for the newer members. These are PDF files I've uploaded to MEGA. Honda CB750 Service Repair Manual 1969 - 1978.pdf (47.4 MB) https://mega.nz/#!BMhQWAgJ Key: !XCF-31C5fGyJ3trO_63IoX86b5JfjUcS-8rE97vIYNk 79-83 CB750 Service Manual in PDF Format. 28 pdf...

I just had my pants pulled down on ebay, said a bit of a rattle ??? mmm and said fork seals all good, no pi55ing out, so I need a cam chain, I want the one with a link, I know i people say not to use a link and split a new one, well I am nor willing to take all the time involved to replace by...

Either the bolt unscrewed in the wrong spot or some one has added something or the F is different from the owners manual I down loaded. There is a block about 1/2-3/4 thick between the filter and the block. It was getting dark so I wasn't able to explore much but it looks factory. Looks like...

Good afternoon ladies and gentlemen, I am new to the Honda CB750 scene with my 1998 Nighthawk. The bike is immaculate and almost completely stock. I am looking for information on where to go, who to talk to, and general information about gear and parts. First, I would like to make the bike...

So, I think I messed up the right front fork on my bike... 1982 CB 750 C. I pulled the fender off because it's quite beat up, but after riding around for a bit and doing a bit of riding on some rough roads I've gotten fluid leaking from the right dust cap and the front end is feeling pretty...

Gentlemen, disregard my earlier post about my clutch and trans. I was confused and asked the wrong questions. Now I have another question and will try to ask it correctly with the proper terminology. My bike came with PODS and stock 4 into 1 exhaust and the previous owner had put 122 mains, 42...

I'm new to the cb750 family. Could someone point me to the manual for the cb750k? Also, another question. Does anyone know the difference between the cb750c and the cb750k? Looking for cafe bars and grips and I found a kit that says it will fit the 750c but not the 750k. Any ideas about that...

Ok so here's the deal. My bike is running really rich, its carbon fouling spark plugs left and right (literally went through atleast 16 in the last 3 months trying to get it right.) I made sure the mixture screws were set according to the clymer manual, the diaphragms are in great shape and the...

Hello Ive been fixing up a '73 K3 over the past year. I have it on the road now but there is a constant oil leak when I run the bike at higher speeds. In the city during calm ride it does not happen. The oil appears to be coming out of the overflow hose from the oil tank. I have lowered the oil...

Hey guys, I just picked up a 97 nighthawk cb750 last week, with 40k on it(well, says 40k, but the speedo/odo wasnt working when I got it, so who knows...). Anyway, the bike seems to run great, but for some reason I am not getting the MPG that I think I should be getting. Right now, on the...

My road trip is being seriously delayed because of electrical problems. Is there anyone in this area that can sell or lend me a flywheel puller for a couple hours so I don't have to wait until the end of the week to have one shipped? Would be greatly appreciated!

The oil level on my K2 tank falls off the dipstick within 2-3 hours of engine shut down. When I installed the oil pump at the last engine re-build I checked that the oil shutoff valve in the oil pump was seating o.k. [I couldn't suck any air past it by mouth]. The oil tank held it's level at...

Question for those in the know, what the best Manual for reference that includes torque settings & comprehensive details regarding tear down & rebuilds? I have found the Haynes ones to be pretty good but is there something better out there? Thanks Rob

After a lot of great input from the forum I am pretty sure I have stuck rings. The bike runs well but fouls the plugs (I am running NGK D7EA plugs) after about 60 miles. Is it possible to loosen the rings without taking the engine apart? Say maybe a tablespoon of Mystic Mystery Oil (or...

I have been struggling with running rich and fouled plugs ever since I got it running. 1978 SS with 6100 miles that runs well with new plugs. I finally ran a compression test today. Dry test #1-80 psi, #2-75 psi, #3-70 psi, and #4-70 psi. Wet test #1-85, #2-88, #3-82, and #4-90 psi. I know...

Hello gentlemen, Assume I have all of the cable adjustments properly taken care of, so please rule that out. Brand new cable. I have no idea what grade oil the previous owner filled the bike with, he drained it because he thought the bike was being shipped and then put new oil in it when I...

To all those which have searched for an alternative rebuild kit for the 75/76/77 CB750F series rear master cylinder know they are hard to find and expensive when you do find them, I rebuilt mine with the kit designated for the GL1000 Honda part #43510-371-305. It's exactly the same as...

Hi there, I checked today the valve clearness on my CB750F 1980, all 15 valves where in the correct tolerance except the the 2 exhaust valves on cylinder 4 that are well to close, I couldn't even insert 0.002 inch feeler gouge, very tight, almost no clearness at all. I got this bike from a guy...

I have a stock '78 Super Sport that I have been "cleaning up" for a while. I have gotten lots of great input via this forum. It has always run rich although it is slightly better than when I got it (plugs always have a black, fluffy coating). I found that the jets were two sizes too big and...

Advice from all would be appreciated regarding the new gas formulations and the inside of your tanks. Do you seal anyway just to be safe? Or seal only if you need it? Someone mentioned the old tanks and new gas corrode faster?????? Others have said unless you need it sealing is more of a hassle...

'78 Super Sport with 6,000 miles. It has always run rich since I got it last fall (on my 4th set of plugs). Just for fun I screwed the idle circuits fully closed and I am running pods to try to lean it out. It started right up and I took it out for a couple of miles. It ran great. In the...

I have been fighting some tuning issues for some time. Now I am thinking it may be heat related. The bike always starts when cold but seems to foul plugs a lot. Today I started the bike from cool, not cold, and let it run for less than 10 minutes. Revved it up a few times during that period...

So I have a 78 750F that I am building and I have had the stator rebuilt and in my manual it says the "rated resistance" is 0.2ohms. I'm wondering if that has to be exact or is that around about number. After the rebuild the stator reads 0.4 to 0.7 ohms resistance. Is this b/c I do not have it...

My bike seems to start and run fine, but when i pull the throttle into higher rpm it cuts out and i lose power? It is a 1979 cb750F, I put new plugs and wires on it, but the problem was not solved, any suggestions

Hey guys, I just picked up a 1997 750 nighthawk yesterday! I've been scouring the internet looking at all kinds of parts websites and trying to figure out which would be the best one to use as far as pricing and quality are concerned. I just wanted to know where ya'll typically get your parts...

1978 bone stock Super Sport, stock pipes, stock airbox, but Cycle X ignition (just installed). After cleaning the carbs it developed a problem with sooty spark plugs. I got a lot of good advice from the Forum, mostly from Dirt Digger. Charging system good. However, I assumed that the jets...

1978 Super Sport, stock with clean carbs, 6,080 miles. Started running rough one day, like it was only on two cylinders and sure enough 2-3 plugs were sooty and 1-4 plugs were clean and wet. One coil was dead so I bought new plugs and the Cycle X optical trigger ignition and coil. Big...
