maintenance

Hi all, I just got an '81 CB750C (Custom) and am looking for a basic toolkit to keep on the bike at all times. Other than buying the individual tools and creating it myself, I was curious as to whether or not you all may know where to find a pre-arranged roll/kit/pack. Thanks!

Hello, I have a Nighthawk 750 and it has some problems. I have a new 12 volt battery in the bike, but it still doesn't want to start. I know that these bikes don't like to start if the volts go under 12, but is this a fixable problem? And if so, how can it be fixed? My second problem is that the...

Hey all this is my first post on this forum. BACK STORY- I just recently got my first CB 750 yesterday, its a 1978! When i arrived to the seller he started up the bike, it started right up. It wasn't the prettiest start up iv ever seen (some black smoke) but it was running. Then i asked to...

I have a 1981 CB900 Custom with 24,000 miles on it. The clutch has 6 normal steel gear plates (Clutch Plate A, Honda part 22321-425-000) and 1 unusual and at this point nearly impossible to find steel gear plate (Clutch Plate B, Honda part 22322-425-000). I have seen this referred to as the...

Does anyone know of a alternative rear brake master cylinder? Mine has pretty bad rust and corrosion from years of setting. At this point i don't think rebuilding is an option. Does anyone know of another brake master cylinder that bolts up the same?

I noticed that the fork seals are leaking on my 1982 CB750C. While researching how to replace them I'm coming across things like progressive springs and valve emulators. Both sound like good ideas. Do any of you have any experiences or recommendations, good or bad, on the subject? I do only...

Hey guys, I recently bought a 1982 CB750C and having my first issue. I've ben riding the motorcycle everyday but recently started having this issue where the e-start wouldn't work. It would sound like the starter is spinning but not engage. Check out this video: This isn't my video but the...

Hey gang - so I've joined the club of many 750k owners who have had to replace their speedo cable.... Yet, when they got to it the screw for the cable at the base was stripped out (or they stripped it). Does anyone offhand know the size of that screw that would be needed to replace the one...

Hello this here is my bike Now to get to the point. Bike doesn't hold the charge after charging it. I charge the bike, great, it works fine charges hold. When I turn it off, bam! Doesn't wanna turn back on right after I switch it off. The voltage slowly starts going down to 11.5. I don't...

Hi everyone. I have inherited a 2001 CB Seven Fifty. I tried starting it and I have two problems. First is it won't ! - I will trouble shoot that, but I could be back :-) More important is that I tried to start it with the pulse generator cover removed and it appears that oil is running into...

I have a '78 cb750k that I've recently got running for the first time in over 2 years. Very exciting stuff. I do have one issue though. My right side solenoid, for cylinders 2 and 3, is heating up tremendously. I had the original coil on it, bought a new(used) one thinking it was the coil and...

As I was riding my 1980 CB750K on Sunday the bolt that holds the stabilizer to the rear hub decided to evaporate, or at least that's what I think happened. I was on the highway going about 60-70 mph and all of a sudden I felt something snap and the bike went all wonky. Luckily I was able to gain...

What are the differences (if any) between 1982 C (@79HO) & 1983 SC (@66.5HP) ENGINES Wikipedia shows the '83 SC being 749CC and 66.5HP. While the '82 C is 748CC and 79HP. What are the difference between these engines?

Just got myself a 1973 cb750 chopper and it was obvious the carbs had problems, thing wouldn't even idle. I took apart the carbs and all the floats were off and carb 3 had a stuck float valve. Finally, I got the float valve unstuck and adjusted all the float levels to the level it says that...

I have a 1981 750K. I brought it in 2012 -running perfectly This poor maligned beast then sat in a leaky freezy garage for two years while I have been doing house renovations. (Yeah, I know, I hate myself too). Bringing the machine back to life this summer, I have worked through the more...

Did I read somewhere on here that there is a spin on oil filter to replace the stock filter on a 1980 750? I think someone said it was an auto filter that worked quite well? I'm just thinking that would be easier to deal with than the stock set up. Thoughts and opinions?

I have a 78 CB 750 SS with a Lockhart Oil cooler attached. The previous owner added a header which was causing the oil cooler send and return lines to melt on the header. I tried multiple times to re route the lines but after countless failures and oil mess, I have decided to axe the cooler all...

Hello all, new to the forum. On my 1973 CB750F... Bike was running fine, then started running pretty rough after sitting in the shop most of the winter. I put SeaFoam in the tank, didn't clear anything up. Kept running really rough, coughing, spitting, cutting out, mis-firing, etc. We checked...

Hi all, I just picked up a nice 1978 CB750K this weekend. I've had a few bikes, but this is my first Honda 4, and I think it is waaaaaaaay cool. It's bone stock at the moment, and I promise to get some pics up soon. PO said the carbs were cleaned (I don't think so), the plugs replaced...

Just adopted an orphan 74', multiple foster homes, no records, last one didn't winterize it properly. While I wait for certain tools to come in I figured I'd pull the carbs and clean them. Prior to pulling the throttle was very stiff to open/close, since these models have to dual throttle cables...

Hey everyone! I'm new to the forum and have looked at about every post here trying to figure out how to get my bike going again. When I first picked up the bike it wasn't charging but a quick look at the rat nest under the cafe seat showed some wires undone from the r/r. soldered and connected...

Hi there, Last summer after I got my rear tire changed, my brake stopped working. the brake pedal presses completely down with zero resistance. I've read that it may possibly need to be bled, anyone have info on how to do that?? I know how to do it in a car and i've seen some videos of bikes...

Just near end of last season i found the proper gauges for my 1981 CB750 DOHC and welts putting them on i pulled some wire harnesses apart to clean it up in my head lamp a little and when everything went back together didnt quite work the same. So heres the just of it, my turn signals no longer...

I have a 1981 Cb750 i have the tiniest hair line leak of oil on my head gasket, which only causes me issues really, once i have stopped riding my bike and its parked, and leaning it on its kickstand, drips across the base of my engine and onto my shifter pedal. i was just wondering if there is a...

I hope this nasty winter ends soon for all of you living through it. So, I have one of the most horrendous clutch rattles I've heard yet. In neutral at idle it sounds like the bottom end is chewing itself up. Pull in the clutch lever and it's better. Carbs are synced as well as I can get...

I've got some leaking from all 3 (I think) screws on the face of the crankcase cover. I noticed the PO seemed to have some silicone around those screws, now I know why. That seems like a bad method, especially as it doesn't work, so I'm wondering what the solution is if anyone has had this...

So I ordered a complete gasket set and last night I tore open my motor because I had what seemed to be an oil leak between the two middle cylinders. Ive done some research and I'm assuming the leak is being caused by the black rubber pucks, if anyone else has any other ideas feel free to inform...

Hi. I'm looking for a DL'able manual for a '79 CB 750 K. Searched the Forum - found nothing! Anyone know a site where I can find it? And of course, some more serious service manual would also be of interest. TIA / Jake

Hey, everyone I'm just curious if anyone can point me in the right direction, towards replacement throttle cables. Thank you!
