i have a problem with running my Z turbo when i give full throtle it wount take it, the carbs are standard,can that be the problemthe fuel pressureregulator is from Malpassi and the pump from gpz1100,im stuck cant see the problem,Help
I posted in the other thread ,but forgot, are you sure you have all your carb vents plumbed into your air box
What does "it wount take it" mean Lean out, run rich, detonate This tell the readers what advice (if any) to offer............
good point , I just assumed (silly me) it fell flat ,as in "out of gas" , I know the story of "ass/U/me"
all4 carb vents are fixed in to one andi usethem to controlthe vaste gate/boost fuel regulator/dumb valve.
when i race it and give full throttle it ´detonates´and the air fuel monitor goes down to lean,it simply vont go higher then 0,2barand over 5-6000 rpm
the outlet on the tankis from pingel and the inlet is a bit bigger
sorry im not good at english/USA

You are indeed leaning out because your venturie pressure is greater (boost pressure) than your floatbowl pressure. You MUST vent all 4 carburetor floatbowls to the plenum (carburetor box). Plumb your wastegate, blow off valve, boost guage and boost sensitibe fuel pump to the plenum. DO NOT use carburetor floatbowl vents to operate the item listed above. By allowing caburetor venturie pressure to rise above floatbowl pressure you are actually forcing fuel out of the floatbowl and AWAY from the carburetor. This is the one thing which gave Kawasaki the edge for years with the pressurized airbox of the ZX11. Fuel pressure MUST remain 2-3 psi above boost pressure to move fuel into the carburetor floatbowl. As long as fuel pressure is 2-3 psi above carburetor venturie/floatbowl pressure, fuel will always move up and out the main jet as required.
Ok but i have boost preasure on my floatbowls! the connektions sits under the carbs and is connekted to the airboks,but the 4carbvents witch sits on the top are not connekted to the air boksis that vrong,
Make sure the floatbowl vents are connected and not the overflow tubes......
to clarify for him ,,,all over flow lines should be connected to the suction side of te pump ,, all vent lines run to the airboxOriginally Posted by rajay
Overflow lines to out side air pressure. Vent them as normal. Start at low boost and get a feel if this is working.
