start putting penetrating fluid on the bolts now - holy crap were they siezed and needed drilling out and re tapped
(i know its not easy as they are screwed in tight but every little helps)

the pump is a low pressure pump which once it gets to it psi wont pump further (untill engine started and pressure drops)
obviously a fuel leak after the pump would cause this to keep pumping continuously
-you said you can smell fuel which really points in the direction of a leak
and as you said the bike starts with difficulty that is pointing to the carbs not having enough fuel
so i would check that your drain screws have been shut properly touch your float bowls and see if they are wet
and that the pipes between the tank and carbs are not kinked anywhere
when you stop for a ride wait a few seconds then kill the engine with the kill switch wait a few more seconds and turn kill switch back too run - if you hear the fuel pump then it is not getting the fuel it needs at any time
-you will notice we are checking all the free to do things first and what has been or could have been touched

avoid messing with carbs where you can - i love them and find it relaxing stripping them down but soon will be my job so i have my excuses
(dont worry guys discounts to foc-u members will be available when i get my new place doing sonic cleaning)

looks like you have done a ht cap replacement (angle on the photo looks vertical)
did you do that recently and did you remember to trim the ht leads slightly ?
a smear of silicone sealant on the ht lead outer coating before you put the cap rubber on can seal these better - i use grease sometimes if its a bike i am working on a lot but only because i dont want to seal it for long periods of time.

ok got confused untill i read previous posts
basicly they let air in while your throttle is closed (pilot)(sorry if im writing this in basic terms but its easier for newbies in the future)
so if your float needle valve is open and letting in fuel your main jets are effectively closed so this is the easiest route for your fuel to flow through
- 90% sure its a jammed float needle problem
could just be a bit of crap made its way through if not its a new needle valve assembly 5-10 quid on ebay but make sure you replace the whole bit and not with (ooh there was a bit of that in a spares box)
hope its making sense i am better at doing than explaining (which is why i fail written exams lol)

thanks for that - distracted and didnt search - so there is another thing to have a look at MR Destruct lol

gonna do a compression test tomorrow as a problem has shown up and if all looks well then i might just have to take my carbs off for a but of adjustment
will try and remember to have a deeper look into the carbs for you - might be a video so i dont have to do a shit load of typing
-wish i had my own carb balancer i really should buy one at some point but cant justify the cost at the moment so will continue with a length of tube and my ears (cant wait till my dad goes deaf then i will be better than him at it lol)

sometimes when things get slightly confusing imagine
spinny spinny sparky spark bang bang whoop 

if its only cracked it could be repaired - mine was same but the cage was twisted to buggery so went the naked route instead
-apparently the police were not happy with the naked route and told me to put my clothes back on

fitted the sd05f spark plug caps
and checked the pod filters were not fowling the carb inlets - got to hit the dyno when i get the pods i really want

mentioned this post to a couple of ppl over the weekend - i have never seen so many faces of WTF

draining off the carb always best way to go where posibleooh yeah thats your problem right there
go straight to the float and float needle valve my guess is its simply closing far too early or even just sealed shut and that 7ml was just sitting there
or there could be some crap behind the needle valve but a quick blow through the fuel line will show that (just block the other 3 fuel needles)

im not laughing i promise
-thats why i label everything with masking tape and a sharpie when it wont be obvious after all the work
