Honda-SOHC

I just tried to download the CJ250 workshop manual but the link didn't work - is it me doing something wrong or has the file moved please?

Thanks guys,
Engine fully stripped this morning - had to wait for a castle nut tool to remove the centrifugal oil filter thingy.
So far looks promising but have now given everything an initial degrease / clean so I can have a close look at all the bits tomorrow.

You're both right about the oil filter - the centrifugal bit was pretty well solid gunk and the oil filter pretty messy, however there didn't seem to be any major damage evident from initial look (although may be different once I have a closer look at cleaned bits).

I've got two pretty well complete 250's, a spare 250 engine and a complete 360 so hoping to have enough good bits to get two full bikes up and running.
The 360 has a really good condition exhaust on it although the silencer is for the 250 - I'll probably use that on the 250 as a full restoration and the 360 as a decent runner with some universal silencer or other.

From the stripdown it seems the cam chain tensioner is different to the 400 with a simpler horseshoe mechanism - again all seemed in decent condition so far.

Cheers,
Andy

Oddjob,
Interesting test - I've tried almost everything else with my carbs and they still leak like a sieve as soon as petrol is turned on.
As they're back on the bench I gave your idea a go and the pressure drops steadily with 'dry' float needles but as soon as I spray a little WD40 over them they seal and hold pressure.
This is with new DSS float valves fitted - tomorrow I'll put the old ones back in and see if they are any different.
What I can't understand is that the flow is so strong when the fuel is turned on that it seems hard to believe it's just leakage past the needle.
I did wonder if there was maybe something that held the floats down and I'll have a good look at this possibility as well.
Also when trawling t'interweb there are some comments on setting fuel height rather than float height and I wondered if this was an option on the 400. Certainly on the GS and GSX I've got that is the way they are set, using clear tubes from the drain plug. I did see some comments saying this could be done on the 400, set at around 3-4mm below the float bowl joint.
The saga continues
Cheers,
Andy

Thanks Oddjob
Price was for both tanks and they are in surprisingly good condition - the photo makes it look like the 'back' tank is marked but that's just reflection.
They both have a couple of small dents and a few marks in the paint but do look original so I guess that's to be expected.
The guy wasn't sure if they'd ever been fitted to bikes as the insides are so clean - one is absolutely perfect inside, the other only very minor staining visible at the very bottom but not any rust so maybe he was right and minor damage is just from storage and handling.
The 'original' tank on my bike is shown below - strange damage to paintwork and rusty inside but pretty free of dents.
I hoped the new tank would save the bother of de-rusting and painting etc. and as the bike is not completely original and in 'aged' condition I think this will actually fit in better than a perfect painted tank.

Hi,
Been sorting through a pile of manuals etc. in the garage and scanned a few setup manuals in in case they are of any interest to anyone.
One is a CB750 - doesn't say what type but I think it's a SOHC early one with spoke wheels and 4-4 exhaust.
If it's of interest maybe someone can remind me how to upload / send it somewhere to add to the Cave.
Cheers,
Andy

Thanks again for quick response on the tank - really appreciated.
I'd spotted the ad on Gumtree and the guy had someone interested but hadn't come back so there was a bit of pressure to decide quickly.
All worked out well and collected them yesterday afternoon.
Turns out there are two tanks, both the same and appear original paint in sound condition with a few dinks and marks but both being amazingly clean inside.
The tank I've got is quite rusty inside, the cap is poor and the paint awful so I'm hoping to use one of these as an easy option.
Only shame is that neither one has a fuel tap. [ Guests cannot view attachments ]

Thanks Oddjob,
This is the tank - looks like a 400 fuel cap.
