And when removing the gearbox ensure the end gears and roller don't fall off the shaft.
Interested in as to why? Also, because I kinda don't wanna buy new bearings if I can avoid it, but also don't have a slide hammer, are there any alternatives in cleaning the engine, where I can leave the bearings be?

Ok, so when I get in there, assuming I don't need new bearings for cam shaft or transmission, do I just let them sit in there when cleaning the engine up, and then regrets them before assembly? Can I clean the transmission assembly without taking it apart?
Also, when the engine is taken apart - what are some good tips for cleaning out the cogs and innards, and also the case, both inside and outside? I don't want to vaporblast it I think - I don't mind the worn look too much. But I would like to clean stuff up as good as I can while in there.
Lifting out the gear shaft on my 400 was easy again how far you want to go in stripping down a gear cluster is down to what you find once inside. I found petrol was very effective but did use Evaporust to remove some surface rust on some internals.
I took lots of photos to help with re-assembly - my only regret is I did not do more written notes alongside the pics as I did forget quite a lot of stuff. For the 400 there are some good U-Tube videos that I used as a sort of revision lecture - when I was confused I asked questions on this site.

Out of interest when I did my rebuild I did not do any soda blasting. On the outside I washed with petrol using a paint brush, then paint stripper with some fine Wet & Dry paper to remove the darker oxidation being careful to not go onto any contact surfaces. I used Petrol to remove oil film stains stains on the inside of the casings with some more stubborn staining being removed with either brake cleaner or nail varnish remover. I did paint the exterior casing parts rather than polishing as per original Honda.
Ah, thank you for this. So you cleaning up the inside with petrol as well? Did you tape over ball bearings and such, or did you have the engine stripped down completely? Obviously petrol will evaporate, so there shouldn't be any reason to worry about petrol getting into small crannies and nooks on the inside of the case, eh?

I ended up with 2.65mm because that’s all I had. Fingers crossed they do the trick.
So - following up on this - did the 2.65 o-rings do the trick?

Hey all
When I got my Cb550F2, I got a Dunstall Power muffler and header with it. I haven't been able to find much information on it, nor find one attached to a Honda bike. Does anyone here know anything about them?

Okay, made a list gathering the items listed. This is helpful.
Primary Chain
Cam chain
Cam chain tensioner blade
Cam chain tensioner cushion
Gasket Kit
Seal Kit
Primary Drive Cushion Rubbers
Non Pattern Tensioner
Bearing Guard
Don't know about the last to items though - bearing guard for where? And never heard about non pattern tensioner. Is that the cam chain tensioner, or?

Thank you all for your answers! I have gained hope for a complete restoration, and will go into the deep (bottom) end on this bike then

I have yet to dive into the bottom end - would start that proces in a few weeks, but if the consensus was that after 50000 miles, they weren't worth repairing anymore, I wouldn't spend my time on it. Money is not really a problem - just doing it for the fun and as a spring project. With that being said, part of the reward is of course still to complete a nice build and get to drive it quite a few miles afterwards. So I basically asked to make sure that I don't spend my time on a fools errand by taking it apart. I have no idea if anybody has ever been in the bottom end before, or how it looks. I fixed the top end, and both cylinders and pistons were in okay condition for some more milage, but with the slack I saw in the primary chain, I am not sure it has been taken apart. There is no rattle to an extent that I think the chain is digging into the oil gallery. I have a video if the bike idling here - maybe you guys can hear something I can't? https://youtu.be/3XW8BiG1dDk- Alex

Hey
Ok, så got this CB550F. It had some top end work done, and it runs fine now. The primary chain is loose and needs to be changed, and contemplating doing a major restoration of the engine.
The old lady has 80000 km on her (yes, that was five zeros). Do we have some sort of guideline as to when the engine is not worth working on anymore? When do you just run out the life of the bike, and when do you continue to restore?

I have found several sellers on eBay selling this part, but they all state the part is for different models. Sometimes its for the K1. Othertimes the K2 og K3.
I have the CB550 F2 1978.
Did the switch signal switch for the CB550 change at all during all the models, or can I use one from the K1 on the F2?
