It won't start

I did a little more work on the ram air first thing, then tried to start the bike.  There was quite a bit of prep work beforehand, getting the radiator plumbed up and getting some distilled water plus sorting out the cam chain tensioner.  I wussed out fitting the manual one and will  probably get Steve Jordan to fit it for me when i get the bike dyno'd (or at least find out the definitive way to fit one.)  I also had to turn over the motor with the CDI disconnected so i could fill the filter and oil cooler with oil.  After thumbing the starter for a bit to get the motor filled with oil i had to top up with almost 3/4 litre.

So anyway, the good:

• I have good oil pressure (the light goes out when turning over the motor)
• All the electrics seem to work, the rewiring is good.
• The fuel pump works.
• It almost started once

The bad:

• My carbs arn't sealing properly and are flooding the motor, bad enough in cylinder 4 to cause a hydraulic lock and fill no1 cylinder with fuel.
• I'm not sure if my pump stops pumping when the float bowls are full (i just assumed it would), in the end we disconnected the pump and tried to start it direct from the tank
• The sparks from both coils seem a bit lame, but that might just be how they are.  They did seem a bit better with the UK spec CDI.  Still nowhere near as powerful as the kart ignition I used to run on my MZ.
• The old battery is really really lame, We had to hook up to a much larger battery as the old one would probably only be able to start the bike once maybe twice, it turns the motor over quite slowly.  Hopefully my race battery will be much better, but still we plan to fit some plugs to make  using jump leads much easier.
• My fuel lines leak and need clips on every connection.

I'm going to take the carbs apart tomorrow morning and see what's up, hopefully we'll get it going tomorrow.  It felt like it was about to fire just before it flooded the first time so i think once the carbs are sorted it'll go.
