CB500/550 / Re: Crankcase Breather
« on: August 20, 2023, 07:35:56 AM »
The rebuild was carried out by a classic Honda specialist and had a rebore with larger pistons so I assume they are OK. The oil isn't pouring out. Just enough to wet the end of my finger

Thanks guys. I'll check the oil level in the morning.

CB500/550 / Crankcase Breather
« on: August 19, 2023, 06:23:43 PM »
Hi all. I've 1500 miles since having an engine rebuild and have a small amount of oil coming out of the crankcase breather. I think this only happens after I've ridden it at higger speeds than normal. Is this something to worry about?

CB500/550 / Carb jets
« on: July 19, 2023, 07:24:07 PM »
I've got a Cognito Moto airbox on my CB550 and my plugs are burning too rich. To get the revs down at idle I've have to turn the airscrew right in. Just one turn out to be precise. The bike runs and rides lovely but after a couple of hours the plugs are covered in soot. If I turn the air screw out to try and lean it out the revs climb. The manual idle screw is right out so I can't adjust that any more. If I reduce the jet sizes will this help? I'm thinking less fuel will reduce revs and lean the mixture at the same time.

Yes. The float bowl overflow went away after a couple of hours riding. It was intermittent at first then went away completely. I'm hoping that the pin on the float sorted itself out and somehow has straightened itself out.

I haven't taken them apart but when I had the carb off I looker for them but couldn't see them. I'll have to try again!

Are there only 2 air mixture screws on a cb550 carb. One on the left and one on the right or am I not looking hard enough for the other two,

I've ordered a new float and pin as I'm taking all the advice I can get. Thanks

That's very helpful. Thanks. Maybe it seeps past the o ring with the vibration of the engine.

I have previously polished the pins. I push them out with a piece of stiff wire. If it overflows again I'm going to remove it to see if it's bent as that would make sense.

Yes. Fresh fuel. When it's not raining I'm going to let the bike sit for a few hours with the fuel on and then to go out for another ride to see of it overflows again. I just can't see what else it can be other than debris. If the float had a hole in it it would have carried on overflowing when I got home so it can't be that. Even if the level in that bowl is incorrect why would it overflow one minute and not the next. Onwards and upwards!

I readjusted the float levels and did a bench test
 No overflow for a couple of days. I refitted carbs and still no overflow. Then I went out for a 20 mile ride.  One carb overflowing like you wouldn't believe. I head home, park her up, turn the fuel on and no overflowing.  I want to cry!😭😭
