The 'carb inside the engine' phenomenon you've just discovered was fairly common practice with small rotary valve two strokes (think reed valves, but a different way of induction). Yamaha and Suzuki also used this layout.
Does the small end bearing wobble when the pin is put back in? I seem to recall that the rollers in the cage move freely and are pushed outwards when the pin is in? Was a good few years ago when I last played with 2 strokes 🤣 Good luck with the rebuild, lovely little bike 👌🏻
I have just been gifted a 1992 from my brother, I will start to restore it in a few weeks (my first bike 🥰) and using it to get me through my test. I can't wait to start my relationship with this beast 😁
Before you start spending money on parts or work that you don't need, you ought to find out what the service limits are of engine consumable parts. The concern is that in particular with the small end bearing, you're feeling 'end float' and confusing that with actual wear. Not all bearing movement is a 2-stroke is bad.
ok thanks yes I will do that, so far I've only ordered the parts for the bottom end which did look worn, the top end parts may be good to go again - I'm intending to put it all together and see how it runs next

Thanks Lee, yes there's a lot I need to learn about 70s and 80s two strokes, love the engineering on this bike
Sir "spare parts available its there?
Very good video

Great video!
Thanks!
Watching with interest. I have a 1992 (not as nice as yours) and a 1889 for parts in the garage when I get time to rebuild

I got 4 off them. Gen 1 gen 2 gen 3 and gen 4
Its call GTO 125 in asia ( Thailand) great engine very fast for a small 30 years old bike.
they are fantastic bikes, nice engine!
Hi Josh. Nice work! Would love to share my collection and experience with you. Let’s talk!
Waiting for the part 2
Coming very soon, 80% done
And you should replace the rotary valve cover too its worn out
it looked ok when i had it off i think, too late to do it now 🙈
@@shadyjosh5 replace it to avoid the probability to get ur engine siezed.
