HondaCB650

"If I turn idle screws in all the way I can bring down to 1.5krpms." How many have you got? Shouldn't there be only one idle screw? At this point I would say "Whatever you did, undo it and put it back how it was and don't worry about a little bit of any rattle from a nearly 40 year ol...

TBH, I have no idea what that that flag is supposed to be, there was another guy on here from the UK when I first started using this site and he was using the Union Jack flag so I just grabbed the one I'm using as it has the small Union Jack in it . Well at least the bike is getting a bit better but...

Hi WT, "A night owl huh? Me too." No mate, its just after dinner here in the UK

Electrics is where I start pulling my hair out :roll: but my very basic understanding is that the alternator supplies the power for the spark and the battery stores up any left over charge to start the bike or at times when there is a greater load than the alternator can put out, like having lights ...

1982 SOHC CB650SC Nighthawk side panel covers wanted, colour doesn't matter as they will be repainted.

If possible I'd take it for a ride, give the motor a chance to see what it'll run like under load for a distance rather than have it running at a stand still. See if a good run will burn off the fouling so to speak.

Please forgive this question: Is there not oil in with the advancer on the CB650? I ask this because it's been a long time since I actually WORKED on a CB650. I have much more experience with the DOHC Honda's of that same era (CB900C, CB750C, etc) and there IS oil in the on those models. The oil is...

How do I lube it? Do I just slather the whole thing with oil or grease? I been meaning to check my air gap in there but I dont have the brass feeler gauges but since it ran lean before Im guessing that wasn't it anyway. You have to take it apart, have a camera at hand to take pictures so you know h...

Sorry. Been tied up lately.

What you get up to behind closed doors is nothing to do with us

Hi, When you say fouling, what are the plugs being fouled with? Are you running stock air filter or pods? Ahh pods sorry just read your original post. Has it been rejeted ? Main jets etc? Rich Hi Rich, WT is using the standard airbox with a K&N filter, I'm presuming his jets are standard. WT, h...

I thought it was getting a bit busier TBH, there's been a few new members over the last couple of weeks.

There can't be much room left on your ceiling with all those bikes stuck up there

Have you put a new air filter on it? You need to eliminate any air leaks at your airbox, airbox rubbers and inlet boots and fix your leaky exhaust before you try to set up your carbs properly. The choke may seem to pull and return but have you actually checked to see if the choke pulley has returned...

Hi JB and welcome to the forum and the World of Two Wheeled Nutjobs :lol: How long was the bike stood for? Did you do anything to the engine other than have the carbs cleaned? Have you checked for a bit of freeplay in both of your throttle cables and your choke cable? doesn't need to be a lot. If yo...

Hi WT, can you put your mixture screws back to what they were before you did the extra 1/8 turn then take the bike for a run and check the plugs again?
