Project Board / Re: Teds new project a CB500 K1 mostly version 0.5 circa 1972.

Well done Ted. It's been some journey post 800 on page 54. Just look and admire your work but I'm sure the ride will be equally rewarding.
The 750 always was too heavy for me. Even the 500 is a lump to heave onto the main stand for me now. (the foot lever is not well angled as it has to avoid the pipes.)

Great news Ted. When you’re knee deep refitting the kickstart mechanism and primary shaft this moment seems an age away. Well done and let the tweaking begin 👍

Never done them on a PD carb, but on my F1 I needed to carefully tap them out from the inside with a pin punch.

Hope this helps.

Hi Bryan and thanks,
Do you mean push down from inside where the slide goes in? Unfortunately the system will not allow me to post any pictures at the minute.

Thanks

In theory, with main jet removed it should push down from the top but i havent gone that far with pd carbs, i usually point blank refuse ro work on them.

I went with the FA13V ones in the end, as I found a cheaper supplier!

Thanks for your help!

Good luck with the SBS ones, they squealed when I used them.
They're now in a box under my bench with other bits and bobs labelled shite...

I'd complete an more in depth version of Bryan's assessment.

If you've transmitted any grit or other debris into the bearing by cleaning, then they can sound bad.

Really wash it independently (only tgat shaft and bearing) with something like paraffin, then clean that all with strong mix of washing up liquid to completely remove anything that's in the bearing.

Completely dry it with compressed air or hairdryer, then you can recheck for any unwanted radial movement.

Now put clean engine oil into bearing and assess what it's like for smooth movement. 


Thats a good idea. But I think I'm going to be better safe than sorry and while its fully stripped replace parts that can be replaced. Some of the bearings in the crank case were pretty bad. I'll clean them up once they're off and if they seem ok see if anyone would like them.

Just spoke to John http://johnoldfield.co.uk/ and he has some in stock so I've ordered them. I'm already in deep so whats another £100   :'(
It generally takes alot to wear them, any unwanted grit makes them feel awful if not cleaned out.
