yep that was one of the ideas i had, but i would still have to make a return line to the tank from the engine bay surge tank the the fuel tank i think.
I wonder if i just made the return line connect back up to the suction of the pump? might have to do some experimentation

are you willing to sell the extractors?

Yeah extractors would be great but having trouble finding a set that fit. No one can tell me for sure what fits.

One little tip for people contemplating this conversion is that bike carbs can't be fed from a fuel pump, they must be gravity fed.

I couldnt get it to run right for hrs until disconnected the stock fuel pump and just connected the line up to the tank. It is lucky in a 1000 wags that the fuel tank is high enough to allow gravity feeding. I think ill only be able to use 1/2 of the tank though. Ill have to sort out this issue later.

Jet settings to get it to run right
pilot jet - drilled from 0.68mm to 0.9mm
main jet - drilled from 0.98 to 1.10mm
just in case anyone wants to use the same carbs

Ok bit of an update
Put the cb900 keihins on this weekend. Was a bit of a bitch to get them to run right but succeeded in the end.
Has quite a lot more power than the stock carb and great throttle response.

The manifold is made out of 304 stainless, tig welded together.

still need to find some air filters or make a air box

I am talking Naturally aspirated. That is what this whole thread is about

i would like to see a 200hp+ a series with 8 valve head.

It is just not realistically possible

Yeah i agree with you about the 15's, they look too big.
I am definatly not going smaller than 13in tho because they wont fit over the brakes im planning.
It will be lowered further when it passes a roadworthy and gets rego

A few more photos of the vb10.
All put back together and the engine running. Just waiting on glass and a reconditioned radiator
Put the polished jellybeans on, what does everyone think?
Which wheels are better?

dodgeman is exactly right. I should have been more clear.
explosion was a bad term to use. The combustion process takes "time" An insantanious explosion would cause our engines to be blown into shrapnel.
The mixture is ignited and the flamefront expands out

There are two causes of pinging in an engine

Pre-ignition- This is caused by a hot spot in the combustion chamber that ignites the fuel/air mixture before the spark plug ignites the mixture. The Pinging sound is caused by the two wave fronts (spark plug explosion+hot spot explosion) meeting and the resulting expanding gases creating a frequency similar to the natural/resonate frequency of the metal around the combustion chamber creating a "pinging" sound.

Detonation- this is the spontaoonious ignitiion of the fuel air mixture before the spark plug ignites the mixture. It is caused by high combustion temps(high compression) and or too much combustion pressure(ignition advance+compression). Detonation is usually the one that puts holes in your pistons. The pinging sound is created the same way as above. It is from two pressure wave fronts meeting

cheers for the comments, it took a lot of time. A lot of cold sw victoria nights in the shed sparying sanding, spraying, sanding, spraying etc.
i think in the end 4+ litres of polyester spray putty was applied and nearly all of it rubbed off again.
Dont know if i like the colour yet. I am thinking i should have gone a burnt orange colour. i have always loved old datsuns in that colour.

Plans now are to put back all the interior and trim, mount the battery under the passenger side dash and rewire. It should be then ready for some glass and a roadworthy.

Once i have full rego the engine will come out and get some extractors, bike carbies cam, springs, a14 valves and some porting. Looking for a 5 speed box aswell. I want to do some long trips in her so dont want to be revving like crazy
