You need a hand impact tool. You hold it twisted and hit the end with a hammer. Extremely useful on Japanese motors. Use on all Philips head screws. Probably cost less than $50. Once you have one, you'll look at a screw, and think, let me use that tool on it. That tool allows you to loosen screws almost every time with no problem. Plus you can reuse the screws instead of trying to find new ones. Look them up online. I have three, and used one on my Honda 125 today.
I have one and you are right, I have commented on many videos how I think it is my most useful tool. I did try using it on this but as it's an aluminium casting with a narrow base I didn't want to start beating on it as it would eventually crack or warp the separator.
Well, you have inspired me Richard, or shamed me into it, one of the two! I am curious to inspect the condition of the clutch on the CT125, so took off clutch cover, removed four 10mm bolts and their springs, circlip, and the three pesky screws to access the oil pump came out with no trouble. Presently stalled, in need of the notched removal tool. I have seen them on ebay, but would you happen to know a part number?
Richard, were you able to replace those three pesky oil pump fasteners? Thanks for posting this work, I have a CT125, have been a bit reluctant to get elbow deep in it like you are! Cheers
No, I didn't. I placed a parts order and forgot to include the screws 🤦♂️I only realised when I was assembling the filter again. Next time I clean it I will change them.
The secret to engine work for beginners like me is to film yourself, that way you have references to go back to., It's really why these videos get made.
hi Richard - help needed - when refitting the gear selector dose the nibs on the back of the fork have to be pushed over the lug in the casing by the selector drum
Morning Roy. I'm not sure that I fully understand the question. Have you watched my later videos on reassembly of the engine, the answer may be there ?
on the rear of the gear selector shaft there is a spring with two prongs coming out do they need to be forced over a lug on the case be the selector as I can see wear marks on the lug or dose it just butt up against it
Hey! We restorating same engine right now and we have to remove crankshaft sprocket ( small one timming chain sprocket) Do you know how does it hold on? there are no grooves...inside of the new spocket is round and smooth...If we pull it off, is it matter how the new one is put back on, becouse there are no marks or grooves...Thanks!
I honestly don't know. I'm leaving mine in place. The manual doesn't describe the removal either. I suspect it's a specialist job. Are there any witness marks on the gear ?
@@richardjweeks Ok, thanks! Maybe we have to leave it this time also. There are wear marks, some round corners, but will run sume time I think. Nope, there are no marks. We thought maybe its been put on hot and holds tight after. But thats just a guess.
I've had a cb-125s for years. This video series is a godsend! Gives me the confidence to tackle the job.
Thank you for the positive feedback, I'm pleased they are of use to people. Good luck with the cb125s project.
It’s been a year since you’ve posted how’s the project?

One of the most descriptive videos out there you should be a teacher this has helped me tons!!
I'm pleased it if some help.
With
the oil centrivical filter top.drill the centre of the screw out.The head will come off,then you can remove the top.Cheers Graeme

@@royburns7496 no, they don't need to. Be forced, the selector shoul only engage with the drum cam
The wear marks are from. The studs that hold the selector fork from slipping off the selector cam.

@@dacebergmane6778 good luck, speak to a local bike engineering company, they may know?

Thank you, it's been bugging me. Regards Richard
