Re: 1981 CB650C
Good to hear about your progress. As you said fine tuning of carbs at this temperatures does not make much sense. When you come back to the idle screws in spring, have a look here: http://www.hondacb650.com/viewtopic.php?f=4&t=11695 Kind of complicated procedure but the reactions look promising....

Re: 1981 CB650C
That's good news.
Also good to know that this kind of marks seem not to hinder functionality.

Re: Taillight but no Brake light
This is quite exactly what I had in mind with regard to the surprises you do not want to detect during trying fixing electric issues on the road. I think that this main fuse box looks as it does as a consequence of some other electric issue that was not fixed for a quite long time. Now I would check...

Re: Taillight but no Brake light
Independent of your present problems it might be a good idea to find time now for a comprehensive check of the 40 year old wiring harness. This means to have a close look at all the wires, disconnect and disassemble each connector for inspection and cleaning of the contacts. Often also worth a look ...

Re: Taillight but no Brake light
Welcome here! :D "brake light sensor box" sounds special so this is probably something special of the 1983-on DOHC. So I am sorry I cannot help here directly. Possibly one can simply unplug and bypass this part to see whether the remaining parts of the brake lights circuit work as they sho...

Re: 1981 CB650C
Some people here successfully installed aquarium equipment from a pet shop.
If you do not like to trust that plastic stuff with fuel even small stainless steel T's may be available that way.

Re: 1981 CB650C
If you are able to get the starter clutch disassembled inside, you should be able to get it together there, too. Good idea to be really attentive during disassemble and take many pictures. This is my point of view but for you the work that you are going to do has to fit your capabilities, your avail...

Re: 1981 CB650C
Welcome here! :D Needs some care but looks still like in good shape. The stickers and the stock rear sprocket suggest that this bike has not seen that many miles. The 4-4 exhaust also still looks reasonable. So you very probably have a good basis there. Looks like the engine side carb clamps are mis...

Re: VB44a slow speed jet plug
Welcome here, Lee! :D The VB carbs came with two different types of slow jets. First were just plugged in but the VB44C (1982) should have screwed in slow jets. Just to mention why there might be VB44 parts that your VB44a do not have. For details on the CV carbs, have a look at the manual linked he...

Re: 1981 Honda CB650 Custom Main Crank Bearings
Thanks for the confirmation of CB 500/550/650 four bearing shell compatibility.
Hope you got everything together and running.
Sounds like things were not that straightforward.

Re: 1982 cb900 - Where to source choke spring? And is this broken/bent?
Here are nice pictures that illustrate a similar problem: http://www.hondacb650.com/viewtopic.php?f=4&t=1134#p6743 In this case one end of the thinner spring got out of its groove. In your case I think both ends of the smaller spring are in correct position but the spring really does not look li...

Re: Troubleshooting starting issue 1982 CB650
This looks like the PD carbs airbox.
Not really sure but I think I remember that the airbox side boots of the carbs are not exactly "coaxial". Which means turning them in the airbox by some angle would allow a certain adaptation of heigth and width.

Re: Troubleshooting starting issue 1982 CB650
Also, maybe I'm impatient with the warm up. It's 80 here daily and I don't need choke to start and idles 1200 straight away. It is a fact that the CB650 requires much longer warm up to run reasonably without choke than most other bikes. I did a test by taking airbox cover off and it seemed to ride ...

Re: Troubleshooting starting issue 1982 CB650
PD50 carbs should not fit the black cylinder head at all because of different intake spacing. A "clean solution" could be kinked carb boots but sometimes people force the carbs somehow into the boots. This is very susceptible to cracks and airleaks. If you take off the carbs be prepared to...
