We survived the deluge riding back from Derbyshire on Wednesday 😁😁😁 It was still very nice to get away for a few days even though the weather was typically British at time 🙄🙄🙄
Out and about in the Wolds this evening and a stop off for a Coca-Cola at Revesby.

CB350/400 / Re: Oil Pump
« on: July 10, 2020, 10:47:15 AM »
Excuse my ignorance but why has the CB400 have a double oil pump? I could understand if it was dry sump with separate oil tank like the 750 (scavenge pump and feed pump) but 400 is wet sump. Most cars are wet sump and have single pump.
The small one feeds the gearbox.

Welcome to the Forum. What are your plans for your bike?
It was my father's but he's past way now. If just finishing what he started it's had a few mod on engine but I'd rather not say because I got loads of abuse on the other forum

CB350/400 / Re: 400 - “elasticity” in headnuts
« on: July 08, 2020, 07:42:38 PM »
16 ftlb is the spec, so I overshot it a bit with 30Nm. Still the flexibility is weird to me.

Nope, studs have not been removed, hence standard stuff.
I have the correct washers 10 thick copper ones, and 2 with the rubber insert.
🤔🤔🤔 As you say, the flexibility is very strange and anything that flexes can't really give a good hold. Unless by tightening to 30Nm has stretched the studs a bit, dont forget the equivalent of 16ft/lb is the absolute maximum torque. I think mine are done at about 12-14 ft/lb.

30Nm is approx 20 ft/lb, which sounds very high. Did you remove the head studs as part of the rebuild?, Have you stripped the threads on the bottom of the studs? have you got the correct size copper washers in place, because if they are too thin, the nut can come down too far on the thread and not hold. Are they standard head studs or stainless steel?

I have now changed 12 bikes to Historic, all done at the local post office and a totally painless, instant process. Only 2 more bikes left to do now, in 10 years time 😁😁😁😁

Sooner be on the 750 in the rain, having no rear mudguard must mean the back of your jacket gets filthy
No Ken, it's me rucksack that gets filthy 😁😁😁

K2-K6 'I think Julie means "dry sump" as opposed to clutch'
Yep, that's exactly what I meant Nigel 😁😁😁😁

Hi, yes I am sure I did as was very nervous of not getting that right. However I have now started wondering. I hope that isnt the issue! Just wondering how much oil there should be
Being a dry clutch system ( as opposed to a wet clutch set up) there is never going to be a huge amount of oil there and TBH I wouldn't know how to describe or even take a guess at how to describe how much you should find. But, I would be slightly concerned it's not getting enough oil as you have found one restriction in the oil feed, maybe there is another restriction somewhere in the way of a debris blockage.

Did you make sure you had all the bronze bushes on the gearbox aligned correctly so that all the oil holes line up 🤔

Stunning scenery Julie, worth getting a soaking for.
That's not Trigs 'Build a sohc for under a grand' is it, looks great if it is👍.
Haha, no Dave, this isn't that bike, this is a UK 750/4 K6.... He has finished the 'less than a grand' bike and its bloody stunning but I haven't finished making the seat cover for it yet (as Trig reminds me daily 🙄🙄🙄) so not on the road quite yet.
