Honda-SOHC

Just thought I would post a couple of updated pictures and a new video clip of my cafe racer.

The bike has now passed its MOT, is taxed and insured and being ridden as often as I can.

I have a 1978 CB550K3 with Kehin PD46C carburettors, I need to change the main jets, but I cannot see how to change them.

When I remove the main jets they are attached (very well indeed) to the emulsion tubes, my Haynes manual carb diagram show that they are pressed together with an O ring, now this must be a bloody good fit as I cannot see a join. 

Am I (well my manual) correct and that they need separating or am I missing something simple?

It has been a good and frustrating day.

I had problems with the bike semi-starting (started and then died after a few seconds), but it was missing something awful, then realised I had the plug leads the wrong way round, for some reason I was counting cylinder 1 on the right side of the bike not the left (DOH!!!!).

After I realised what an idiot I am, I tried the bike again, it will start and sounds good but again only for a few seconds.

Now I know the problem is carbs (oh no I hear you all cry).  I have cleaned them and made sure the jets are clean (I will take the carbs off and do them again just to be sure), I can also start the bike fine with the choke on but it dies again when the carb is off, so I think there is a blockage somewhere.

However what I need to do is set the float heights as one of them is leaking petrol from the overflow.

Can somebody please let me know how to check the float heights correctly?   i.e. where do I check them and how (carbs right way up, carbs upside down etc).

Many thanks

Hi Everyone.

I have been lurking on site for a little while now and I thought I would say hello and show you all my CB550 Cafe racer that I am building.

I have stripped everything down, refurbished parts, rebuilt the engine and generally had a great time (and still am).

This is how it started about 3 months ago.  Yes my Dog (Frodo) likes the bike.




Stripping it down.




Powdercoated and polished wheels.



My seat unit that I built with a massive amount of help from my Father-in-Law and the upholstery that I did.





Rolling chassis.



Tank fitted (tank is from a CB500T)



Exhausts mocked up and as it stands at the moment.







Well that is it at the moment, I have just fitted a new front brake as mine had the bleed nipple snap in the caliper.
