    Sip Tech please - re: SiP Road exhaust for PX200


    Hi guys,

    What carb and ignition timing changes do I need to make to run a SiP Road on a standard PX200 please? I have tried it on my tuned 200 but have gone back to a PHBH30 and old Taffspeed pipe.

    Hi,

     

    it needs only a 120-125 main jet.

    No change on ignition is needed, but you can run it cooler with a adjusting to about 18-19 degrees BTDC.

    If you run it with a SI carb - drill 10 holes in the cover around, and a 8 mill hole over the main jet in bottom of aircleaner

     

     

    Thats all what to do to run it smooth.....

    What about if you run it with a 60mm crank and 1.5mm spacer at the bottom on an otherwise stock engine?  I'm running 18-19 degrees timing holes above idle and main jet in the air cleaner and both 120 and 125 main jet is pinking.
