Re: Flasher are not flashing

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.

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...

Try removing your side cover and air filter and check for fuel inside your air box.

Re: fuel leak at crankcase drain hose

I have a 1981 CB650 it has just started to leak gas from the crankcase breather systems drain hose when parked after a ride after it has cooled down. Any body have any ideas?
