I have come to the conclusion that those that snigger are the ones who have made the same or similar mistake in the past and they are sniggering at themselves 😀😁😁. At least you are having a go which is highly commendable. Also worth checking everything else is correct in the gearbox whilst you are there, just in case.

Good point. Engine is out, accessories removed and bolts removed in the correct sequence. Fresh Honda Bond grips well! I am leaving that to tomorrow when I have restocked with some appropriate language and tackle the case splitting and gear box if I get in.
Thanks,
Greg

If you didn't start out to do it you'd certainly never learn anything, so all good experience.
I always think the saying " you learn from your mistakes" is so true. As long as you proceed with care and check as you go along then these things can be picked up and sorted out.
One of the best elements on here is support and guidance honestly given.

Ladies and gents. I can say for a certainty that I would never have contemplated a complete engine strip and rebuild without the information and support that is provided by this forum. I’m sure I will have many questions in the future but for now a great big thank you.

Don't forget when rebuilding the gearbox back into the crankcase ensure its put together while in neutral the pip on the selector barrel visible through the switch hole The outer selector forks have the flat sides facing the centre the centre one will be self explanatory

McGinties 3rd law states that if something can be fitted the wrong way round somebody somewhere will doit.
This is why RR jets now have one end of the rotating element bigger than the other.

Quick update.
Tried Oddjobs suggestion, still unsatisfactory, so proceeded with splitting the case.
Ok, let’s start with the simple stuff. The left and right selector are marked with a cast L or R and numbers? If so I had them correctly fitted which means I had fitted something else incorrectly. Alas I rushed in to quickly assuming I knew what the problem was and missed my original assembly error. I had a quick trial fit this afternoon cross referencing with Haynes and Honda schematics and all looks correct. Alas I am now away on my 5 day shift so a partial replacement of the lower case and test will have to wait.
Thanks to all,
Greg

Don't forget for the dogs the left is on the the right and right is on the left as you are building the engine upside down.

Got it, you should see we twisting and leaning back. I almost wrote L and R on appropriate hands.

Ok, after a bit of workshop time I have a question or two.
First up with the gears set in neautral, brass bump showing and all looking as per 42.8c in the Haynes manual. If I rotate the main shaft the counter shaft rotates as well, should there not be a disconnect? I have not stripped the gears just washed and examined. This brings me to the second question. The counter shaft bottom gear has excessive radial play, I assume bushes are available and it’s a press out press in job.
Thanks,
Greg

Ignore the first question. Having sat and looked at the diagram I asked myself the question, could the first gear have been put back to front. Question answered, doh.
