Honda-SOHC

That's a bit of a blow. They've been through ultrasonic cleaning.....twice! The 1st time, they stood for too long without lube & the sliders stuck so needed freeing up but after the 2nd clean, the sliders are moving smoothly.

Would it be a full "strip & separate" job you're suggesting? I'd like to avoid that if possible (but would also like to put most things back together once rather than twice......or more times).

Hi Clunker,

Thanks for the offer of the arm.

Is that the centres of the bolt holes across the tops or?

I'll go number hunting this evening.

Hi there all,

1st time posting on here so, hello, here goes - some time ago (years) I bought myself a "project" - a completely disassembled '76 CB550 (de-tabbed & already hooped bare frame with EVERYTHING else in boxes & bags) that's been sat waiting patiently for me to get my backside in gear. I've no experience of building anything like this & only a basic mechanical knowledge but I'm armed with a manual, a box of tools & a big bag of enthusiasm so what could possibly go wrong???

There are parts that aren't CB550 (the forks look like they could be from a CX & the rear brake looks like it's from a 750) & there are definitely parts missing - some could be more of a challenge to find than others - such as the petcock, rear brake switch (in fact the entire wiring loom needs starting from scratch) & loads of nuts & bolts etc. etc. but nothing - other than the subject of this post - that's particularly fazing me (yet).

Well my backside's in gear now & I've finally got round to doing something with it (it's going to be a cafe racer - think Seaweed & Gravel, Brady Young Black & Tan / similar kind of thing) with much of the work so far being cleaning, tidying & painting of the "big" bits. The bottom 1/2 of the engine is built (with the top 1/2 painted & ready to bolt back together) but I've picked up the carbs & there seems to be an arm missing in one of them as can be seen here...

I think I've tracked down that the part that's missing is (at least part of) the arm set but I've no idea about the significance of it not being there (hope that doesn't sound too stupid a question). And if it is needed, what the parts do I need exactly, how difficult an issue it is to fix & how I go about fitting whatever's required (I wasn't planning on taking the carbs apart to that degree but if absolutely necessary, I suppose I'm going to have to have a go)?

You can assume a healthy dollop of novice confidence at spannering in terms of tackling jobs.

Many thanks for any help you can offer.
