GN125H valve clearance troubles (No clearance?)

[Drew]

As for some reason I actually bothered to look at the parts Fiche
Attachment 315695

If you look at 7.,8, 9 this is the valve clearance adjustment

I really cant be fucked arguing about this, but I'd love to know why that means the clearance can't be checked between the rocker and the cam.

The rockers are attached to the top part of the head the valves to the lower the cam is sandwiched between them
Remove the upper cover and the clearance is whatever distance the two parts are placed away from each other.
That's why Drew there is tappet adjusters on the other end of the rockers. Accessed through the inspection covers Same as a million other Honda singles of the XR/CB/XL/SL/CRF family.

I am aware now of why it can't be done on a GN. I thought you were saying it should never be done my way.

This is what a fucking GN125 rocker box looks like inside



The motor has been the same forever so fuck knows what springs he's talking about unless they made a major change with the chinese models

Rather than wasting more of everyone's time

I'm sorry if anyone feels that I've wasted their time, but I haven't needed any help at all since the second post in this thread. After I realised that there was a spring holding the rocker in place, the tappet adjustment was a breeze.

Maybe they made a major change with the chinese models? idfk. I do know that that picture is different to mine.

If that engine came of a japanese bike, it has to be nearly 20 years old. A lot can change in 20 years,

you didn't supply a picture.

Yes, they are. I took the rocker cover off and saw the springs with my own eyes.



At TDC on the compression stroke the cam lobes are facing down.

Well, the rocker is attached to the head cover, and to get to the gap between the cam and rocker i'd need to remove the head cover. As to why the engine is designed for checking the valve-rocker clearance rather than the rocker-cam clearance, I dunno. Perhaps so that you can both inspect the valve stem and adjust the clearance through the same inspection cover. But seriously, you'd have to ask someone who actually knows what they're talking about



what does that even mean?

I didn't need help after I realized the rockers were held down with springs. After that, I was able to take care of the clearance no problem. Also, I'm not going to post a photo because I'd need to take the head cover off again, and like hell I'm messing around with the RTV again.

How do you know this?

No one is going to talk me out of this. Like I've already said, I saw the springs with my own eyes. I took the header cover off (the valve springs stay in the head, and these springs were definitely attached to the head cover) and they were applying a torque to the rocker arm, and therefore a force from the tappet down into the valve stem.

It's possible that I was mistaken about what I saw, but it's very unlikely, and no one is going to convince me of anything else. Maybe a picture of what I saw and an explanation of how it isn't what I thought it is, but "nope ur wrong" isn't going to convince me.

With all due respect, That fact you had to take off the rocker top proves you were doing it wrong, That's why the head has rocker inspection caps

Yeah, they put disc brakes and alloy wheels on them and they rust faster

[h0dgep0dge]

You're right, because to take a picture I'd need to take the head cover off again, which would involve taking the seat + tank off, and then fucking about with the rtv, and I really don't feel like it. If you're honestly just looking for more information, when the head cover was off I could push the rockers one way, but they would spring back. If you're not willing to take my word for it, idrgaf.

I'm fairly certain there's a problem with the cylinder compression, and if there is i'll be taking the head off this weekend. If I end up doing that, I'll take a picture of my rockers, just to get y'all to be quiet.

I started by taking the inspection caps off, but when I found that I couldn't feel the clearance I took the head cover off to see what was going on. That's when I found the springs. Once i knew the rockers were being held down by springs, the head cover went back on, and I was able to do the clearance no problem.
