Personally I'd feel uncertain about having something so far off standard in the engine. Ultimately it comes down to budget, I think a second hand shaft from Steve at 400 four bits wouldn't be mega expensive. Last time I looked he had one in stock.

Yeah cheers I know what you’re saying, from what I can remember the main shaft and primary shaft are only capped at 1 end so as Ted says Honda did it for a reason. It may have been an old engineers modification years ago, there’s no noticeable wear on anything so who knows  :-\

Y'know, this might be a stupid pie in the sky suggestion, but back in my irreverent younger days I had owned a couple of CB750's, and the final drive shaft on those had a quill feed to an adjustable outlet on the front sprocket. This enabled you to keep the rear chain lubed using engine oil which was flung out by centrifugal force. Ye gods it was effective and bloody messy! So most riders closed the nozzle completely and lubed the time honoured way.  Just wondered if perhaps Honda, on their wisdom, had ideas of possibly doing the same with the 400, but didn't go ahead. Just a thought!

It looks like a bit of a bodge to me rather than a Honda job, the holes not drilled in the centre either. I did have 1 comment about it would have been done to stop any gearbox wine but after hours of googling I can’t find any information about it

I did wonder if it was caused by someone dismantling the shaft with some sort of weird puller !
