Whats everyone's favorite? Its almost riding season here in Chicago. After looking into more than I did last year (my first year with the bike), it seems not everyone thinks that GN4 is the only thing you should put in your bike. I didn't know any better last year and spent all that money on...

Hey all I'm going to be ordering new points and condensors along with new coils. What would be the correct points gaps it's a 1975 cb750F thanks in advance :thumbsup:

I occasionally see a drop of brake fluid on my rear swing arm (pretty sure because it eats through the paint). The reservoir cup always seems to have a very light fluid "sweat" on it even if I wipe it off. The diaphragm and cup seem to be in good shape with no apparent leak source. I am...

Would everyone be willing to post their method for keeping the spokes and rims rust free? I did a site search and came up empty, maybe I didn't search right. I live by the ocean and my spokes rust just by breathing on them. After I polish them I put some wax on but that only helps for a little...

Doing some reading around the web about cleaning or rebuilding carbs and I have seen people stating that teardown and a good cleaning is all that is needed, while others claim that you should rebuild the carbs. My bike runs well, but last summer I ran some Seafoam through a tank or two and...

1978 Super Sport with 6,000 miles. Low beam was out when I bought it but high beam worked. I bought a new head light and installed it but did not install it in the bucket while I tested it. Right off the bat the low beam works but I notice a little bit of smoke inside the glass so I...

Hello! My CB750F Supersport 1982 wont pass 5000rpm. I bought it in July and restored it entirely. Turned it on a month ago for the first time and since then just low revs to adjust cabs, leaking, etc.. all good so far. Toke it for a ride today. I don't know how to define what it does but...

I just picked up an 81 CB750 Custom. It seems like its in great shape, started and ran briefly before I bought it. Supposedly sat in a garage since 89. There was a good amount of varnish in the tank which I've cleaned and coated. The carbs leaked gas out of the overflows at first, but...

I recently bought a 1976 cb750k. I rode it 100 miles ride home perfectly fine, went to ride it the next day and the bike wont start. I know it has the capability to run. I just want to know what you guys might think is wrong... If i turn the key by the tank i get no power to anything, no lights...

I recently bought a 1982 750 custom for my son-in-law that is in need of some tlc. Among other things, the petcock leaks. I ordered a petcock that was supposed to fit an 82 but it wasn't close. I ordered a factory Honda replacement using the VIN and it wasn't close either. It was considerably...

I just recently purchased a 1976 CB750K as my first motorcycle and was trying to perform a simple oil change (or so I thought), but I cant seem to remove the bolt that holds the filter on or the oil drain plug on the bottom of the engine. Any help is greatly appreciated? ETA-Got the drain plug...

Anyone know or have seen a torque spec for the four bolts that secure the clutch lifter plate?

I recently bought a 1983 honda cb750sc nighthawk that needs a new fuel tank. I'm having a lot of trouble finding one for an 83. Are there any other years or models that have a compatible fuel tank I could get or do I have to buy an 83?

Hey ya'll, I'm working on a 76 CB750 for a friend. It was running great a few years back and then he dropped it on a gravel road. He put it in a garage without doing anything to it and it sat there for 2 or 3 Minnesota winters. I told him I would work on it in exchange for letting me take it...

I counted the rollers and got 88 i then counted the outer and inner plates and got 88 so i`m assuming my drive chain is 88 links long. When i look for a new chain for the 750 these parts sites keep showing up with 110 link chains for the 78 cb750. so the question arose do i not know how to count...

The Speedometer broke on my 78 cb750. I have been looking for a replacement and I can find aftermarkets all over the place but i can not seem to find a stock speedo whether good shape used or stock style but new. I have seen two on ebay but both are in fairly poor shape and I am restoring this...

Hi Im considering buying a cb550 with 40,000 miles on it from a owner who has owned it for over 20years he has taken very good care of it both cosmetic wise and mechanically. Want some advice if 40,000 is it kind of risky Im looking to use as a daily driver and keep it in good condition. :umm:

For those with acewell digital speedos, this is how you calculate the front wheel circumference when using the ANALOG-DIGITAL cable. If you are using the magnet method, just input the actual circumference in mm. Something to keep in mind: SOHC Hondas all have the same speedo drive ratio...

Hey everyone, I'm a newbie to this forum, and also a a new owner of a 1976 cb750k. I got it for around $750 with only 13,000 original miles and is in overall decent condition. I got the carbs rebuilt over the winter and it seems to be running decent, except at idle. I do not have a vacuum...

does anyone have any experience with a spin on oil filter? i would love an easier oil change experience on my f1.

Alright, super noob question. I am a handy guy, so purchased CB750 F SS 1981 in order to learn how to work on it. Very first order of business is an oil change, right? Got the Honda GN4 10W-30 and the HiFlo oil filter and the rubber washers and some metric sockets and wrenches. Ready to go...

Totally new to the forum but thought this would be the best place to figure out my issue with my CB750. My 1975 CB750 started to leak oil out of the overflow tube when riding. The oil is at the right level. When the engine is running the oil really doesnt drip out but as soon as you start...

Hello. I've had this bike for a couple years now and want to completely service it and tune it up. I already installed a new battery, new clutch system, new air filter, cleaned the carbs, and other various aesthetic work. Beyond this, I am helpless. It runs pretty good but occasionally seems...

So I just bought a cb750. 1st bike, though experience with cars. Its a bobber, custom frame, tank, seat, forks, handlebars, oil tank, ect. Anyway, the guy I bought it from said the engine and carbs were rebuilt. I got it cheaper because it wasnt running, which he said was due to electrical...
