Circlip has come off Juitz,l as you suspected when I was telling Ted to make sure to fit a new one.

Yep, confirmed.Found these treasures in the bottom of the sump


This is sub-optimal. Aside from the pain in trying to get the assembly back in without removing the engine. Can I just leave it as is and only use electric start.

This feels like a "next winter" job [ Guests cannot view attachments ]

I would make sure you have all the washers as well. One might be in the ratchet end

Yeah, Def a problem here as I'm missing the slotted thrust washer between the pinion spring and ratchet. Gonna chech my assembly pics but was sure I did this correct.

[McCabe-Thiele (Ted)]

The washer might still be on the shaft end inside with the bigger spring?

Pretty sure you can wiggle them off with a bit of patience - a magnet on a telescopic shaft  might help.

Can't see a problem in using it without the kick start mech in place - you could take the lever off to reduce weight etc.

Yeah found it stuck to the pinion gear.

But all back together now with new circlip. Works again 😄

Thanks again, help as always immensely appreciated 👍

If you did that through the sump you have passed your stage 1 Gynaecology practical exam.

Congratulations on not having to split the cases. What a nightmare. I’ve ordered two new circlips for the kickstart thanks to this forum. A very tricky job completed 👍

Oh dear 😂😂

Stage 2 involves building the engine through the letter box. Challenging.

Hey all, what is the petcock nut size for a cb550k1?

I think it's 18mm but the two I've purchased don't fit.

I could just buy an OE one but would prefer to save £20 😉

Or would one of these be ok to use? The body on mine is ok, it's got the dual output but the tube, orings and gauze are stuffed.

This is what I’m thinking of for mine. Reckon it’s a 20 mm connection

Cheers. Ended up getting one from 4into1 along with some new main jets. Cheaper option than new or the repair kit.

Hey all!

Took my cb550 project bike out for its maiden ride today. Aside from the panicked moment I had when the bike sputtered and stopped, then realised I had previously turned off the petcock it went well.

Carbs need further tuning but I am hearing quite a distinct rattle sound at higher than 2000rpm. Varies if accelerating or not but it's there. It kinda sounds like a chain is rubbing? I have a new timing and cam chain and have adjusted the cam tensioner twice.

As I don't have a previous baseline, im not sure if this is normal? Anything else that I could be?

[davidcumbria]

Do you have the updated valve cover with pegged rocker shafts ?
