I have a bunch of 75k1 parts left over from my first build.
Fenders, turn signals, seat pan, gauges, etc
What are the major differences between the 74 and 75 US models where I wouldn't be able to replacw parts of needed for a resto?

Almost a good result but not quite there.
I fully closed the carbs and started the process again. I seemed to get it to a point where it returned to idle, but when I took it for a spin it stuck at 2krpm again. Seems like when running at full temp it needs a bit of work.
The idle screw is almost all the way in though but maybe has.just enough adjustment to get it to work.

Cheers guys.
Will try again oddjob with your method, otherwise will see about getting jets from Sirius (not wrong about the website). Last option will be Roos courier service!
Serenity now!

Hi everyone, it's been a while.
Had family visiting from overseas so been busy playing host and not playing with the bike at all!
Finally getting back to it over the last few weeks and I'm still stuck on the carb tuning at idle. I'm now at the point where I'm looking at further increasing the idle jet size to a #45 and see if that improves things.
Does anyone know where I can get them in the UK or EU? Have looked at US sites and it's usd$60 to ship!!!

All I can add is NEVER buy a bike in boxes to restore unless you know the the seller / bike. I did this years ago and found out (to the detriment of my wallet) how hard it was to rebuild.
Yeah agree. With a built bike even in poor condition at least I can take good note of what needs to be done during the tear down. I'm looking for a project bike I can rebuild to original state.that I intend to keep. Some stuff will inevitably have to be reproduction, etc. Im a bit wary of the amount money I'll have to spend on replacement parts, especially the exhaust if needed so do want a balance of money invested Vs finished value. I.e. don't want to spend twice the money the bike will be worth (already did that on the last build 😜) and I'm chalking that one up to learning experience.

This could be a good starting point (maybe). Nothing to do with me and I know nothing about it....
Cheers Matt, have seen this one but assume mismatch in frame and engine years will be issue with overall end "value"?

Yeah thanks all, what I thought.
I'm all up for a challenge so don't mind a bike in a bad state, but this one did look far too gone.

Sounds like you may have bench synced with the slides too high
I'll go back and do the bench sync again - went straight into vac sync after the manifold changes.

So decided to take the carb inlet manifold off as I had a suspicion that I had not masked ithe mating surface during painting. Sure enough it was painted and I could see small clumps of paint. Removed the paint wire a copper wire wheel and reattached the carbs. Did the carb cleaner test again and it doesnt stall anymore 👍
Went through the carb vac sync again as well and seems ok-ish.
The bike still hangs at around 2k but it does drop back to 1300rpm idle after a second or two. I did note though pressing on the brass caps on the slider mechanisms it will return to idle immediately. Does this indicate a sticky mech?
Throttle cables look to have enough slack.
Also, bike revs ok up to a semi aggressive throttle twist, but going full WOT instantly the engine will cutout?

It stalls with one but not the other because one is very volatile and the other isn't. What colour are the plugs? Have you checked the rubber insulators for cracks? Are the alloy washers on the vac screws? Probably looks like 1 and 4 because those are the outside cylinders so easier to get the carb cleaner to them.
Have you changed the orings on the inlet manifolds at any time?
Rubber insulators are brand new and I put new orings that came with the vesrah seal and gasket kit I purchased from David Silvers. But I think i am missing the alloy washers on the vac screws you mentioned. Missed these from what I can remember so i'll get some on order if I can find the part no (not seen in the parts manual)

I've got a bit of a head scratcher.
The bike will struggle to return to idle of 1100rpm when hot. It will sit at around 2000rpm. Tweaking the idle screw can help but it's overly sensitive.
So I thought to double check for any air leakage into the carbs, rubber boots, seals, etc.
Was a bit short on wd40 so sprayed a bit of carb cleaner at the carb area. When I spray the inlet manifold my engine will stall. Tried it with wd40 and nothing really happens. Sprayed carb cleaner again and it stalls again.
The engine is hot but I can't see anything being sucked in, it looks like it just evaporates. I'll try again with a cold engine but bit stumped why it stalls in the first place and why with one and not the other?
Maybe need to replace with new oring seals? I happens on cylinders 1 and 4 by the looks of it.

Took the bike out for its first long ride yesterday.
Definitely a few things to address, specifically the sub-optimal idling. But it did a round trip to work (70 miles) and got back in one piece.
Thankyou so much to everyone with all the help and advice over the last 18 months with this project. Bunch of legends!
Like i said, few things to address still but to me a successful build.
Next up will be a 500 or 550 restoration to original.
I'll keep posting on this thread as I am sure I'll find a few more issues 😂

General question - aside from eBay what are other places to look for Honda Fours (500/550). Facebook marketplace search engine sucks and it's pretty much the same stuff that's on eBay.
Autotrader doesn't have anything.
Any other places to search?

I asked when the bike had been restored - 20yrs in dry storage or not, I would change every seal, rubber and bearing.
I also asked for a few up close pics of the exhaust and engine. Nada.
As stated here, too good to be true and iffy. Im moving on.
