    is it safe to do timing to this engine? one of the main difference from the ultra 260 to the 250 is that the engine has now been bumped up 6 points i think.. would it be safe to bump it ahead still>?

    Not recommended. That is very risky.

    maybe i should rephraise my question..
    what is the fastest speed a ultra 260 can reach with mods?. no engine or supercharger mods or turbo however.. i would like to keep the engine internals & supercharger stock for warrenty reason.
