I have a few spare slides, however they look identical to the 500 ones so you need to ensure you're fitting the correct type for the 069a carbs, the needles are slightly different from the 500 IIRC.

As for the broken jet, what carb number is it broken off in? I have some spare 069A carb bodies but not all of them, I'm betting the one you want will be the one I haven't got. I seem to recall I have No2 and No4 but could be wrong. I'll also have a spare choke lever  if that doesn't straighten out very well.

069A carbs will use 98 main jets and 38 idle or slow jets. I may have a spare idle jet, not 100% sure.

Check for markings on the slides, they are numbered to identify them. Also look inside, at the bottom there is some more writing IIRC. Or it may be where the needle comes out.

I'd try a small drill in the jet, slow speed and it may jam, sometimes when you reverse the drill it comes out with it.

Thanks for this, the slides have 2 markings a "Star 2.5" and "103" and the body is No4, As I said above I am going to turn up a drill bush tomorrow and put a 1.5mm drill up it, it will either grab or leave a 0.15mm wall full of holes, hopefully I can pick / ultrasonic any bits out.

I will update tomorrow, John

Hi Oddjob, soory for the 6month delay in replying, got into the strip down and parked the engine and carbs.
Happy new year to everyone. Got my forks straightenged and rechromed though - Philpotts, super job.

I have looked and they are 069A's - which I have now fully stripped down, could you suggest a good rebuild kit?
I think I am going to have to replace the Thottle Slides as well as they are very worn, you can feel the wear easily with your fingers.

Also I have managed to snap one of the pilot jets off in the body, wierdly its not the thread that has snapped but the cross drilled tube at the end, I'm guessing it must have been stuck to the body, these were in a right state inside, soft and solidified white gunk everywhere.

Anybody got any bright ideas for getting it out? ive tried banging a straight pick into it, it seems to lock in the bore but won't hold on when pulled.
I have sprayed copious amounts of WD40 and Carb Cleaner in there.

Hi Bryan. not exactly sure what you mean, picture below is the of the manifolds

Consensus on here is to always use original brassware unless you are changing jetting.

Thanks Johnny, I am hoping to, not taken them apart yet, the barrels do look to have some wear on them, do you think they are OK to re-use?

Thanks everyone, I have emailed Philpots with pictures, I have heard that putting electronic ignition on can help with the flat spot issues? Something I am planning on doing as points always seem to cause issues on old motors

Hi there, I have been a member for a few weeks now, lots of useful info already absorbed, but first post today.

I'm John and I live in Red Lodge, Suffolk

I recently bought a very tatty but cheap CB550 K3 from Ebay, obviously without seeing it.
It is similar to the one I had when I was 21 (Some 33 years ago!)
My plan is a full strip and resto, but I'm afraid not back to full original (Sorry), Matt black with newer lights etc.

I am keeping a record of the Strip / Resto, attached here and I am sure I will be looking for lots of advice / parts when I actually get to the re-build stage.

My first question, given that the front fork tubes are bent, is does anybody have any experience of these TNK Made in Italy ones?
I have looked around at second hand ones, but they all seem to be rather rusty and I'm thinking that new ones might be better?
Any other options welcome.

Thanks in advance for any replies / advice

John
