Ages ago I stripped my 400F carbs down to get all of the parts plated, refurbed etc as the bike had been left with stale (4-star) fuel in the carbs. Then Roy on here sold me a rebuilt set done by Gerben in Holland (jetted for 350F but I changed jets etc for 400F ... carbs were 054A's). Then before I had chance to fit them my mate had big problems with his own 400F and suspected it was a carburation issue .. so he borrowed my carbs and the bike ran well but I obviously needed mine back sometime. Then he called me from on holiday abroad, as he had seen some guy on eBay local to me selling some really nice rebuilt carbs, so I bought them on his behalf and got chatting to the seller when I collected them. Turns out the guy (Paul) rebuilds 400 carbs and sells them on eBay.... I think he has done over 25 sets.  He even fits the carbs he sells to his own 400 to balance and basically check their operation.

So fast forward to a month or so back and Paul called me to ask about a carburation issue that a bloke who bought his lovely CB77 was having.
We got chatting and I told him I still had my old carbs in bits... So FREE of charge he has built me a lovely set and refuses to take payment because  I have given him some carbs bits he needed himself.... he even tested on his bike own (see video).

OK the Gerben ones are OK but these, which Paul has built me, are much nicer... just little things like the correct yellow passivated parts, no mullered screws (yea Gerbens had a few of those) and proper Honda Keihin brassware including brand new main & slow jets. Also Gerben silver painted the alloy mounting bar on my set, which is incorrect.

What a bloody cracking good bloke he is. He doesn't actually refurbish carbs to order ... he just buys sets, refurbs and tests them and sells on eBay.

He is so used to removing and refitting 400F carbs that he can take them off in less than 10 minutes and refit in about 12mins using the techniques he's adopted.

Any advice on the thickness of the bottom washer on Pyramid Parts tapered head bearings when used on the 500K0

I remember on my 750K0 fitting these and the supplied washer was way too thick,  so I had to get it ground a lot thinner and even then the fork ear gaps were still slightly too big.

Someone suggested just using the seal that comes with them plus one or two of the normal washer that is  fitted with the standard ball bearing setup.

Looking for one long and two short CB750 SOHC Cylinder Head, upper crankcase studs if anyone has any to sell me please. Don't mind having to replate them as long as the threads are OK and plain part isn't gouged.


Honda Part No's :_

90033-300-020 Long

90034-300-020 Short

I have decided to move my 1st week production CB500K0 onto my young ex-colleague and good friend from near me on here ...  Ben Powell. He made an absolutely stunning job of his CB350K3 US import, rides it as it should be used, and he's only 30 so will finish the 500K0 and ride it too.

I had it painted in the original Candy Jade (Jet  ) green by Menno some years back and he made a superb job, as always.

I also have a NOS (looks perfect) Candy Custom Gold  fuel tank and original paint, used K1 side panels. The panels were re-clear coated and look absolutely lovely but not 100% perfect. I gave Ben the option of Jade Green or non-standard K1 custom Gold (K0 was Starlight Gold) and he chose green...which I was pretty pleased about. If anyone queries that new  tanks did not come from Honda with the fuel cap and latch fitted ...I have to tell you categorically that you are wrong    .... Pity they never came with the chrome trim though 

So I am asking the 500 afficionados on here what a gold set like this should be realistically sold for,  given that Menno sells a repainted set for around 1500 Euros without the cap & latch.
