    Restrictor should help/stop your oil problems,if you go in your shed/garage run the scavenge for a few seconds when you go in there. My scavenge pump is wired to a  permanent live so I can run it for a few seconds before start up and switch off of the motor,I don't have any oil issues,yes float levels can be an issue to fuel starvation. Glad to hear it's going in the right direction, if you're running a slash cut,shine a torch down it to see the colour of the turbine wheel,this will tell you how it's running,saves looking at the plugs.

    Thanks @Paulm. My scavenge is controlled by the Ignitech ECM and is switched on for 4 secs before I start it. I'll see how it goes. Will alter the floats as suggested. Good call looking at the turbine. Aim is to get it feeling right to save time on the dyno. (y)

    Boss has been out on the Turdo. He's shit hot at setting bikes up and diagnosis on the road. Got 2 psi fuel pump running, engine off. Waiting on some 40 pilots to hopefully sort slight bog off idle. Boost blew the caps of the carb tops so sorted that. Fitted restrictor to the oil feed. Seems to puke oil on initial start after being stood for a week. Maybe restrictor will help. Boss reckons it's his favourite bike to ride, and he test rides everything we do, including ZZR1400's and S1000RR etc. Only comment was it went off a bit after a speedy run, like fuel starvation. Could float heights affect fuel supply?

    This is my set up,are you getting oil in the exhaust while its running? You will almost certainly need a restrictor in the oil line and id advise putting a one way valve in that line as well to stop oil bleeding through when the motor isnt running.

    That's neat. Will look at making something similar. I've read that people fit one way valves. Any links for one? Not sure what I'm looking for.

    2 to 2.5 fuel pressure,drill a fuel main jet to i think its 1mm ,drill and tap your banjo bolt suit the jets thread and fit it to the banjo bolt for your turbo oil feed pipe which i presume is being fed from the oil gallery plug below the ign casing,also either make a small reservoir or use a big bore pipe in the oil return from your turbo,so the oil drains from the turbo properly. I put my pilot jets up one size on my 34s.

    Thanks @PaulmSeems like i need to get the fuel pressure nailed down properly before I mess with jetting. Yes turbo being fed from the gallery plug. I'm gonna see how much oil gets passed by the turbo Saturday. Not sure what quantity should be passed over say 10 seconds, but somone here will probably know. This is my turbo drain set up. received_1217797279617856.thumb.jpeg.10d272699860947864d6d3aec16efad4.jpeg

    Did you check the fuel pressure?

    I had to shorten the spring in mine, 1.5 / 2 psi is what you want.

     

    If you have everything right it should be pretty close to stock, if the bike ran alright before turbo'ing it, it should run ok with a turbo.

     

    Don't guess, meassure!!

    Can't get a steady reading on the inline guage I use for set up, maybe need a better guage.  Carbs are balanced. 
    Main jets size 115.
    Needle clip position second from the top.
    Air screws 3 turns out.

    Will try cutting the spring. 

    Thanks.

    Why do you think that you got too much oil flow?

    How is your turbo oil return made?

    Getting oil in the exhaust pipe. Read a lot now that they normally need a restrictor as the pump delivers too much oil. I have a Facet scavenge pump returning oil to the crankcase above the clutch. Checked the feed pipe banjos and no restrictor is present.

    I ended up going bigger pilots as was lean . Sometimes at the lights it would cut out  .

    I found that bringing  the tick over  up a bit helps when there turbo .

    As for the floats if it's not flooding the carbs I would leave it as is .

    Can you remember how big you went up @colinworth79? Nearly there but idle to quarter throttle is all to bollox.

    Been for the first test run :banana:

    Fuckin awesome, shoulda done it years ago B|  

    Few minor issues. Idle is very hit and miss. Bigger pilots have been suggested but could anyone recommend a size? Rough as bollox pulling away from a standstill. Clears at 2000 ish rpm.

    Malpassi regulator fitted but can't get  steady pressure whichever way I turn the screw. Anticlockwise to reduce pressure?

    Think its getting too much oil to the unidentified 'Chineseum' turbo. Any suggestions for a restrictor size. 

    Don't get a lot of time to tinker with it so any help saves time.
