This may already be addressed in the answers, but I had the problem with running out of adjustment, and it should be easily fixed by changing the gap because that makes a big difference in the rotation of the plate. I think in my case I made the gap on the smaller side.

CB500/550 / Re: New needles don't fit!

A UK F2 should be wearing 069a carbs. However I’ve known a few now where the carbs have been exchanged with a European restorer whose name escapes me right now. He has sent 022a carbs instead of 069a carbs not thinking there may be a difference. I think the 022a were fitted to the 550k models Europe got.

We’ll know more when you find the number stamping.

Hi Oddjob
I'll check the needles in the morning. The bike came completely dismantled with lots of parts missing. It's an F2. These carbs came with it. I was going to change them, but they're in really good condition so decided cheapest was to clean them and use them.

An Update

While I had the carbs off, I also checked all the slider needles; they had the circlip on pos 2,


When you say position 2, is that from the top of the needle or from the bottom?

The 550 might be different, my 500 has 5 positions, I used position 3.

Mine also has 5 positions, it's 2 from the top, which the book says is the default position.

The engine should sell online - ought to fetch £200.
With realistic or no reserve the bike should sell even in the current market.

Its been a long time but my memory says the pushrods fit anywhere anyway, cam followers rarely wear just watch which followers fit which cam, the famous E3134 cam needs followers marked with an R which denotes a different radius, cardboard jammed between the follor rods to fit barrels
