Attached are two pictures of my CB 750s. One is a '75 that I have owned for about 13 years. It's the most expensive $770 bike that I have ever owned. It was running poorly when I got it and I've put massive amounts of time and $$$$ into this thing. The second is a 1971 that I've owned for a...

Thank you.

I'm repacking the rear wheel bearings on my 1975 K5. The rear hub is threaded, but the wheel bearing retainer appears to have a tack weld that keeps me from removing the bearings. I assume this was done at the factory. There seems to be no way to remove this bearing retainer without damaging...

Reply to "the Menace" of Vancouver: I LOVE that 320i in the background. I had one for almost 20 years. What a great car!!

This should be easy. It's time to replace the gas tank on my 1971 K1. I need to pull the badges from the old tank and place them on the new one. I think that the "Honda" tank badges are attached to the tank with two male prongs that are pushed into pinch clips. I imagine that the male tabs...

Before you remove links, count the number of links that are in your existing chain. The minimum are 100 links for the K0 thru K6 with the OEM sprocket, I believe. I recently replaced my 108 link chain with a 100 link, so there is room for variation. If you already have a shorter chain, you...

Thank you for your reply. I see that the gear box under the speedo unit has grease and I plan to clean and re-lube those gears. I don't see any sign of a lubricant in any of the gears of the speedo unit, itself. The gears all look dry and clean. I assume that if any lubricant was used, it...

Dear Forum: Thanks to some forum members and You Tube, I have opened the speedometer housing from my '71 K1 to replace the Speedo face. The inside of my speedometer housing has all sorts of rust and dry dirt. As soon as I loosen the set screw to the trip meter, I will pull the speedometer...

Dear Mr. Grepper: Very good advice!! I went to You Tube and found a guy who showed me how. He tightened a large hose clamp around the thin aluminum ring and then used a small standard screw driver to gently pry the bottom edge of the ring away from the housing. It only took a few minutes and...

Dear Daren: I knew it! I knew that there would be people like you who know how to restore a K1 Speedometer. I must admit that I didn't imagine that I would have to slash & burn my way into this unit. Thank you very much for your wisdom. Now I have a reason to buy a dremel. Sincerely, Steve

Dear CB750 Forum: I have a 1971 CB that I am restoring. It was a little rough when I got it, but time and money can solve everything that is wrong with this bike. I want to tear the speedometer apart to restore the housing and to replace the speedometer face. I've removed the unit from my...

Dear DirtDigger: Thank you for your thoughts. My pads didn't look too glazed, but my rotor does. I didn't realize that these rotors are stainless, although I've never seen rust on them. My '88 K75 must have stainless rotors, too. But the brakes stop very well. Where do you go for...

Dear CB SOHC 750 riders: Tell me how your front brakes work. Many of you have owned more than one bike. How do you think these front brakes stack up? Both of my CB 750s have crappy front brakes. My '71 BMW is really more crude than the Honda in most ways. But it's drum brakes stop faster...

After 40 years, I finally purchased some Japanese Industrial Standard Phillips style screw drivers and can't believe that I waited so long. I also purchased some impact JIS Phillips head drivers, which seem able to get anything out with a few careful wacks. This post is an encouragement to get...

The advantages of Red Coat are that it holds up very well, but can be cleaned out of the tank with Methyl ethyl Ketone. The epoxy creams don't seem to hold up as well and are difficult to remove from the inside of the tank, once applied.

I just bought my 2nd SOHC 750 and have the same problem with both. My front brakes don't grab. In both bikes, I have rebuilt the master cylinders, rebuilt the calipers and adjusted the caliper to the rotor so that it is just a partial turn from rubbing the rotor. I both cases, the master...

The caliper brace bolts to the left fork leg and the fender brace bolts to that. So the fender brace will be closest to the tire.

I used some black flexible plastic plumbing pipe to protect the freshly painted frame on my bike. I cut it to lengths that matched the frame cradle rails. I slit the plastic hose using a hack saw and worked it over the frame tubes and used zip ties to keep the plastic pipe in place while the...

Dear CB750 Forum: No need to reply to this Main Jet posting...........I found the answer by searching the many similar questions and answers in the forum.

Step #1. Get the Chilton Service Manual. Step #2. Get the Haynes Service manual. Step #3. Read both before doing anything.

I recently purchased a 1971 K1. I received 110 Main Jets with the rebuild kit. The bike had 110s in it and ran ok. The parts dealer says that the bike should have 140s. My K5 ran on 105 jets. I just put in 130 jets, but haven't taken the bike off of the lift yet to run. Does anyone know...

It was a cracked float bowl tube.

If you are going into your bike to perform simple service like replacing fork seals, it really pays to buy a Chilton service manual. I have both a Haynes and a Chilton manual for my CB. The manuals will help you to do it right the first time. Replacing fork seals is not a difficult job, but...

I'm not trying to rub salt in your wounds, but even if the original steering head bearings were worn, they would possibly have worked just fine once they were cleaned and greased. High speed bearings need to be far more perfect than the low speed steering head bearings on your old CB. When I...

I posted questions on this web site about a leak from a carburetor vent tube on my 1971 K1. Another owner posted that I should look for cracks in the brass vent tube in the float bowl. That turned out to be my problem. So, Dirt Digger would probably also recommend that once you determine...

I just purchased a 1971 K1. This is a pretty nice bike with great restoration potential, but previous owners have not always treated it well. It has some issues, but the engine seems strong and healthy. I only have about 300 miles on this bike, but when I first took it out, the carburetors...

I am having a similar problem with my 1971 Honda. I can give you a few hints regarding where to start. It may be leaking from the vent hose to the float bowl, if your carbs are similar to my older model. You might be able to trace the leak by identifying which vent hose is leaking and tracing...

Dear Dirtdigger: Thank you for your wisdom and knowledge of the history of CB750 exhaust specifications. Awesome!!!! Sincerely, Steve L

I have just purchased a 1971 K1 and have the opportunity to purchase some Honda OEM NOS exhaust pipes. They are not the HMC 300 that most people prefer. These pipes were made later (1980's I think ) and are marked HMC B 750, but aside from some EPA emissions stuff stamped on the side, they...
