I went out at 3 this morning to strip the cases as it was niggling me so much it woke me up!
Stripped back to bear cases, reassembled and still the same so I'm leaving it and going to build the rest of it up complete. watching loads on the net it appears that others have a much free-er spinning assembly than I do and wondered if it was something to do with the assembly lube being really thick and making everthing drag somewhat? I've never used it before and tbh might not bother again as I really dont like it. Think I'l stick with engine oil next time.

I only used assembly lube on white metal bearings & the camshaft - elsewhere I used oil.
TBH it never crossed my mind to use assembly lube on gearbox parts - I can see that might explain your issue.
Oddjob:
Plus you must wash out any new bearings you fit as Honda fill them with a protective coating of grease which over the years goes harder and harder. My new countershaft bearing only just rotates it's so stiff. Wash with petrol or similar.
I only ever used engine oil on the gearbox when assembling, it gets plenty as soon as the engine starts, it doesn't rely on the oil pump for lubrication. I tended to use STP on the crank bearings and the camshaft surfaces back then. It was like golden treacle and did a fine job of protecting the surfaces until the oil got there. You just don't see STP anymore or Slick50.
Bryanj:
Ooooh slick 50, i remember lister running an engine for about 30 mins with no oil after using that and no damage on stripdown

Because the glare from the polishing will have already damaged my retina’s and I won’t be able to focus, what?
Don’t tell me, there’s two lefts and you hadn’t noticed until now?….. go on
I’ve not been out there and kind of blanked bikes out this week, it’s been such a shocker I’ve not dared go in there
My Honda bearings were the same, they were all NOS and all the same hardly moved at all ex pet u set duress, washed them in petrol and left them percolating in a dish of lube for a day or so before I fitted them and they came out perfect. Re assembly gunk, I used some stuff recommended to me by the husband of a pal of mine, she drag races and atone point was UK fastest lady pr similar, on the funny bikes. He builds her motors and lashes everything in it and I appreciate her motor is stressed to buggery but any helps good help and all that. Perhaps not so in this environment. It really is proper sticky doings!
I know the box gets lashed with oil from the off but thought a) wouldn’t hurt bobbing a bit in, b) didn’t know when the engine would get any oil as might not be rigged up until I get back from Yeee-haaaw. and c) It’s like green treacle,
I mean it’s GREEN!
Well, with a poke of reassurance, I will continue blindly on and attempt to get the pots on and slide the barrels on.
I hasten to add, fitting the second shaft once the cases have gone together by threading it through, is far easier than expected.
Nice one Ken, et all for the advice
