Fuel presure

[HAYA0163]

Hello to all of u!!!
Does any one knows how many psi mast i have at my fuel regulator?
My busa is 00 with external pump.
I think its a regulator problem cos i see only 2-2.3bar.
When my bike is hot hesitates and refuses to start at once.
Thanks in advance

your pmp seems to be failing,I had a bike to do exactly the same thing at the track.I would ride it soon as it got warm it would sputter,pop and shut off and soon as pump seemed to cool it would run fine till it got warm again...

Pump or regulator?

??
Yes when its cool seems fine.
I had to have 3bar(43psi) and i m having only 2bar with out any fuel filter when running cold!!!!
The pump is almost new about 4000khm i think its time for the regulator.
Also i m thinking to buy an after market pump(external) and regulator what do u suggest?
Thanks in advance!!!

Just to let everyone know, my 05 Charcoal busa has 16k miles on it and the other day it died on me.  Sounds like a similar problem.  The bike only starts once, but then it dies after minute or 2 of idling.   When you turn the key, you can only hear the fuel pump every once in a while.  I've checked all connections, and disconnected the TRE and the PCIII.  Ive been looking all over this site to find out what it is.  

I'm also interested in the paper clip diagnostic trick i've seen mentioned.  Does anyone know how to do it?? I've seen this picture but i can't find this white wire in my bike anywere!!  PLEASE HELP!

ok i found the connector to put the bike in dealer mode. I got a c23 code when the bike shut off. I beleive it is for faulty wiring/tipover sensor. I have done nothing to any wiring recently. Does anyone have any suggestions?? Where is the tipover sensor?

Under the tank near to the front seat.It is Grey wire plug.
