Re: High idle help

I removed the carbs while waiting for the new boots to arrive, found that the butterfly plates are all gaped differently when closed as you can see from the pics. #4 is completely closed, #1 & #3 have about a 1/32" gap while #2 has over a 1/16" gap. Also, the throttle mechanism sticks ...

Re: High idle help

Thanks for that. I want to do a thorough check when I pull the carbs off, I'll add that to the list.

Re: High idle help

I ordered new carb boots, which I suspect is the problem. I'll check to ensure the slide is working properly when I remove the carbs, and the choke connection. I also found a video on bench testing slide lift with a bit of compressed air.

Getting ready for first start

All I have left is to bleed the front brakes, then first start. I swapped tanks from stock, the fuel line has a very slight up hill. I hoping this isn't any issue :? since its only about a 4" run from the petcock to the carbs (see pic below). Here's my first start procedure pieced together from...

I'm finally in the home stretch of getting my 1982 CB650SC back on the road. I'm missing the following parts, and they appear to be unavailable online. Can anyone provide a recommendation for a source, or alternate/cross-referenced part number? Clutch cable adjustment bolt - BOLT, CABLE ADJ. 5319242...

Re: New Indicator Lights

Well, I have it sorted based on a response from the SOHC4 forum. As I guessed, and it was a guess, the */red circuit wires from the switches act as ground. Attached is an image of the new gauge cluster. I also moved the ignition switch held in place with a set screw. Also filled in the fork air assi...

New Indicator Lights

I'm working through the wiring on my 1982 CB650SC adding new gauges and indicator lights. The new indicator lights (2 wire) are wired red/+ and black/- ground. I'd like to add these to the 9 pin OEM connector in the same locations as the OEM wires. The OEM wires are as follows: light green/red - neu...

Re: 1982 CB650SC Wiring

I'm not a wiring expert, so I opened the headlight can on my 1982 cb650 (totally stock barn find), and the 2 green, 1 black and 1 brown wire(s) are not connected to anything....Everything works on the bike, so I'll assume the other posts are correct. good luck.

Re: 1982 CB650SC Wiring

Thanks Folsom, amazingly enough I was reading the diagram correctly. Since my new head light bucket doesn't have a tab, I'll direct wire the to the green/ground that went to the tab in the OEM bucket. Looks like the other two ground wires are free and clear to wire to the new turn signals and gauges...

Re: 1982 CB650SC Wiring

Two of the ground wires appear to have 6.3mm female spade terminals, while the third ground has a 4mm female spade terminal. After looking at Old Man Honda's wiring diagram http://oldmanhonda.com/MC/WiringDiagrams/CB650SC.jpg , it appears that they are in fact empty connections along with the brown ...

1982 CB650SC Wiring

I'm getting the wiring harness back on my bike, and either failed to label all of the wires, or some of the labels came off. There a 3 green wires with spade connectors at the front of the wiring harness that share the same opening as a black and a brown wire, and the turn signal wires. Can someone ...

Re: 1982 CB650 Nighthawk Side Panels Wanted

George, I have some, but the posts are broken. Otherwise no damage to the face of either, the paint and decals are in descent shape. Shipping may be cost prohibitive to the UK.
