Re: Hard to start, great when running

Just a stab in the dark here but is your air filter blocked? Have you ever replaced it?

Re: Cylinders 3 and 4 are not firing.

Hi Tommy, you say that there is fuel in your carb bowls but is the fuel getting through to the combustion chamber? After trying to start the bike have you removed the plugs from 3 and 4 to see if they are wet with fuel? If there is no fuel on them I would suspect either blocked jets or fuel rail.

Re: Header on Cylinder 1 is not getting hot like others!

Hi Raiken and welcome. You don't mention doing anything to the wiring harness on this bike, I have found in the past that a lot of problems can be solved by starting with what you already have, but seem to be neglected when it comes to a refurbishment of a nearly 40 year old bike. Most people assume...

Re: Flasher are not flashing

So you are using "aftermarket" flashers? Somebody else recently had a problem with aftermarket flashers that would not flash. The solution was to change the bulbs in the aftermarket flashers for the original Honda bulbs, the bulbs in the aftermarket flashers were the wrong wattage or whate...

Re: My CB650SC Nighthawks

Great looking Nighthawk one man, nice! The other project looks neat as well. Thanks Efferdy :D In the UK SOHC Nighthawks are really thin on the ground so finding parts isn't easy, the bikes seem fairly common in the US but the shipping and import duty is usually way more than the cost of the part t...

Re: Flasher are not flashing

Could you be a bit more specific, are you using original Honda parts? is it all of your flasher lights or just the front or the rear? Pictures might help.

That explains the difference in terminology, in the UK a fuel tap is very rarely called a petcock :lol:

Re: Help on where to connect this tube

Green = Float bowl vents, these do not connect to anything, they are just tucked between the carbs and airbox.
Red = Fuel pipe connects to the fuel tap/petcock.
Where are you located?

Re: Help on where to connect this tube

That looks like your fuel pipe that goes to you fuel tap, if you connect it to your fuel tap and fuel pours on your floor have you checked the clamps are tight and the pipe hasn't got splits/perished?

Re: fuel leak at crankcase drain hose

If you see fuel dripping again then try tapping your float bowls with a screwdriver handle one at a time to see if it is a sticking float. You may be able to work out which carb it could be (if it is a sticking float) by seeing if a quick tap stops the drip. Its always a good idea to switch the fuel...
