Re: 1982 Nighthawk CB650sc Starting troubles

Hi mafic, did you dry store the bike, drain the bowls before storage? You may be getting fuel into your carbs but that doesn't mean it is getting into the engine. After you try to start the bike can you take the plugs out of 1 and 2 to see if they are wet with fuel? I can't really see it being an el...

Re: Wire harness repairs

Hi Hutch, I haven't got anything similar on any of my CB650's that I have come across but that looks like a PO has added an inline fuse holder to me. Probably he had a shorting out issue and sticking a fuse in may (or may not) have fixed his issue. :?

Torque settings

Why are there no exact torque settings for these bikes? eg. 17-22ft lbs for the head bolts? I'm usually a (dirty word alert) Kawasaki guy and all Kwak manuals have an exact torque setting when one is needed. So why the flock does Honda have to be so vague? ps. I love my Kwaks but I'm not bikeist :D

Re: 1982 CB650SC carb cleaning

Why do you want to replace the original air filter housing? From what I've read on this site and others is that fitting pod filters leads to lots of carb problems.

Re: 1982 CB650SC carb cleaning

Hi Hutch, the three screws that you have circled in blue are where you screw in brass inserts for a carb sync tool, more commonly known as vacuum gauges or manometer. The location of the brass insert circled in yellow serves the same purpose as the blue circled screws, its just that it has the brass...

Re: Right gasket set but different head gasket.

Be careful when buying a head gasket for your bike, the top gasket in the picture in my previous post is a genuine Honda part with a part number 12251-426-306 ,some sellers are selling the bottom gasket in the picture with the same part number. My advice would be that if you are gonna take the head ...

Re: Right gasket set but different head gasket.

The gasket at the top is the same as the one taken off the engine, the bottom gasket is the one supplied in the kit. There are more differences than just the camchain tunnel and the front bolt holes being out of line.

Re: 1982 Nighthawk CB650sc Starting troubles

Hi Hamman, my tap is the manual type. The rubber seal had split and collapsed inside the tap and there is a small rubber sheath that sits inside the filter body that the internal plastic fuel pipe slides into. This rubber sheath had worked its way down to the bottom of the internal filter (probs whe...

Re: 1982 Nighthawk CB650sc Starting troubles

Hi Bater, my problem was solved by putting a different tank on my bike with a known to be working fuel tap. Took a few start attempts to get the fuel through all four carbs but now she is ticking over at 1100 +/- Keep us updated with any results or progress you may have.

Re: 1982 Nighthawk CB650sc Starting troubles

Hi Folsoml, I don't know what Bater has done to his carbs but I stripped mine down, all jets out, ultrasonic cleaned all parts, soaked jets in white vinegar to dissolve crusty deposits, cleared jet holes with very fine wire and carb cleaner then chucked them in the cleaner. All diaphragms appeared o...

Re: 1982 Nighthawk CB650sc Starting troubles

Hi Bater, I'm having a similar kind of problem but mine is starting on 1,2 and 3 but number 4's plug is dry. Fuel is getting to the carb but it doesn't seem to be getting to the cylinder. It will run on 3 cylinders but peters out after a very short time, I'm suspecting that the fuel tap may be block...

No spark on number 4. *FIXED*

I've replaced the plugs, HT leads and caps but number 4 will not spark. Any ideas? :roll:

Brand new plug was a dud! :x

Re: Right gasket set but different head gasket.

Hi tario, nobody was more surprised than I was that the gasket in the kit was different to the one on the bike. Check out the differences in these two links, the first one isn't the actual item I bought as that was only shown inside the packet, this listing is for the identical set though. http://ww...
