    Fastest Single pipe Speeds?

    Post up your fastest GPR single pipe speeds. I'm really interested in what the fastest 1200 unported single speeds where.
    What was the fastest anyone went on a 1200 single???

    Just give general mods, size? ported? prop and rpms.



    Here are mine-

    78.3mph 1200 unported All bolt ons, boat prop at 6750rpm

    77.8mph 1300 EFI unported, all bolt ons, 14/22 at 7200rpm

    Thanks. It went 77.2mph on a 14/20 at 7320rpms also. Just all the props I had at the time. But have one on the way that should put it about 7100 and go maybe 80mph
