    Bike was running good last fall before winter storage. Here is the list of what was done this winter:
    Cleaning the carbs with floats at 17,5mm.
    New main fuel jet, fuel screws adjusted 2.5 turn out and shimmed needles
    oem airbox open with uni filter done last year
    Valve clearance adjustment
    Fuse box
    Compression is the same on each cylindre

    When I push the start button the motor is turning but wont start. Spark seems to be ok. Fuel is going through the petcock. When I put full choke on something seems to help. With starting fuel I see fire going out of motor (exhaust uninstalled) but it wont start.. Is my problem related to fuel delivery?? Electrical?? Valves timing??
    Thank you guys for your help!!!!

    The floats should be wet-set. The measurement just gets them close. I do not think that's the problem though.

    Battery.

    Measure the resting voltage, and the voltage drop when you press the starter.

    Fair enough, though it would have been helpful to know that before. Also, the yelling...

    I see no mention of changing the pilot jets. The UNI will create a lean condition relative to the original setup.

    Original Pilot jet and main jet to 115, thats what 6sigma recommended for my setup..
    Wolf exhaust 4in1
    I had the UNI before thats why I put the kit
    Didnt try with a bigger pilot jet..
