I have a 1978 750k barn find I am updating. I am going to a 1980 cb750c swing arm because its about 1.5" - 2" longer and looks completely factory. My rear wheel is a simple bolt on but some modification needs to be done to bolt up. The pivot is .5" too long which is and easy fix. The bearings...

New here. Recently purchased a '75 CB 750 that needs some minor restoration. Looking for OEM style exhaust. Can I make the pipes from an "82 fit?

I've built by first CB750 chop. Amen savior, P&P Girder, 836 kit. My question concerns the nipple on the back of the motor... My aftermarket oil tank has the two lines that connect to the engine, no prob there. A third, smaller diameter spigot protrudes from the bottom of the tank. I've read a...

I have a k6 and I'm having a issue ...when the clutch lever is disengaged none of the lights work and I have power going threw all the ground wires when I pull the clutch lever in the all the lights come on and I have no power coming threw the ground wires so I replaced the clutch lever safety...

Does anyone have a decent set for sale or know where I could find them?

To start, I'll say I don't have the "proper tools" the manual wants you to have to test the alternator, the best I've got is a multi-meter that reads AC, DC, and resistance. I've gone through and checked what I can on the alternator itself: the resistance. the field coil reads about 7 ohms, and...

Hi there, I'm somewhat new here, have lurked for a while but rarely post as most things have been covered, I cannot however find this particular problem in the search. I've owned this 76 cb750f for 2 years now. it ran ok...when i bought but wasn't charging. fixed that with new/proper...

I am helping a friend with his SOHC CB 750. The bike is complete and when he went for a test ride, he went through the gears and when 5th gear was selected, it got stuck in 5th gear. Now the clutch works fine and he can push the bike with the clutch lever in. I suspect the chain tension or the...

Does anyone know where I can get the Installation Instructions for putting a Drouin Supercharger on a Honda Cb750 K1? A pdf would be greatly appreciated. Thanks.

My CB750K exhaust system has just been sold.

Having issues with the battery draining acting riding the. Ike for a few times. Any help Is welcome! Thank you!

I'm chasing an issue with my Battery/Charging System. When I start the bike it turns over aggressively and the engine starts and runs. At some point in the near future (between 20-40 miles) I will grab the clutch, the bike will die and then the engine won't turn over again leaving me stranded...

Hallo CB-Fans, ich habe seit ca. 6 Jahren einen AME Super-Chopper mit einem Honda CB Motor, F1, BJ. 1978. Seit kurzer Zeit habe ich das Problem, daß der Motor meiner F1 im heißen Betrieb und wenn ich einen Kreisverkehr fahre rasselt. Laut einem Vorbesitzer ist der Motor rund 130.000 KM und...

Take a look at the attached photos. Do you think this is repairable?

When I pull up on the choke, the butterflies close and it idles higher. Push the choke down, the butterflies open, and it idles lower. This makes no sense to me. As a side note, the bike already idles too high (4500-5000) so I know the carbs need tuned bad. I’m just confused as to how...

I am probably going to have to split the cases , as the saying goes . So I used a camera probe to check out the cylinders and this is what I have in my 77 supersport . I should have a rounded dome piston , yes ? And this bad boy has 4.0MM stamped on it . Unfortunately this is the only readable...

I finally got my 78 to start after changing the oil and cleaning the carbs (and properly hooking up the fuel line, I put it on the wrong inlet(?) on the carb). Only thing is it idles too high, like 4500-5000 RPM high. The rubber boots from the carbs to the engine are pretty cracked and I...

Hi there I've just put a 1974 CB750 K4 back together and she looks and rides great. For about 10 miles !! Then the battery dies. I've tested the voltage at the battery and its only going to 12.4V when revving. It should be about 14V shouldn't it? There is a chance I got the two or the white...

I have rebuilt mt 1973 carbs, i have a questions regarding adjusting the slide , is the suppose to be any play up top, also how much gap should i have before putting carbs back on bike and start sync process, any help would be must appreciated

Hello everyone. I'm a new member but not new to Honda motorcycles. I'm trying to adjust my high speed idle on my 1978 bike. I followed the book: Pull the choke on; turn the adjustment screw until it touches the cam; open the choke and then turn the screw in two full turns. I understand that...

I’m new to motorcycles and recently picked up a 1974 CB750 SOHC. Got it running and it sounded great. I accidentally left the petcock on overnight and now after it warms up it has a chirping coming from the engine and eventually stalls and dies as it heats up. Definitely metal on metal. I’ve...

I'm trying to find a Split joining link for DID O Ring chain for my CB750 K0 all I can find are full chains? Thanks

Howdy. Owner of a 75 CB750K and after several years of a flat bar decided to go back to a more upswept OEM handlebar. Upon conducting the swap, I noticed the rats nest of wires in the headlight as well as many mis-matched twisted together wires from one of the various POs. So, I purchased a main...

Where do I get a new one that does not leek when turned off 73 cb750 Any help would be great Live n ny

So, although the bike runs fine, I’d like to check the sync is done proper. The compression is checked good, the electronic ignition is spot on and the top end is new and correctly done. So I did a refresh on the carbs because the #2 slow jet was not completely clear. all carbs clear and floats...

While changing the clutch plates on my bike, I somehow lost the spline washer. It is OEM Part number 90432 392 000. It is a 25 mm washer splined on the inside. It is interchangeable with washers from 1976, 1977 and 1978 cb750, either the F model or the K model. I am down and out until I find...
