    Ultra LX N/A & STX12/15 Performance

    What I would like to have is a thread dealing with the two non supercharged Kawasakis. While the hulls are VERY different I know performance gains will be different but we can discuss what works. I know that there are many more 250/260 owners of which I will be also but for the time being I have what I have and would like to tinker with it. There are not many mods out there but we can discuss their advantages, disadvantages, and just plain waste of money. After speaking with a few other members with these skis we would like a little more info than just "go get a 260" ****Just giving you guys a hard time**** I have gotten lots of good help from many of you. I would like to have a place for us budget riders to share.

    Can the timing mod be done on it? I dont see why not? Then would have to run 93 fuel. Unless tha NA ski is already advanced in timing? I dont know, someone who has 15f chime in here.

    I dont think the timing is advanced on the stock 15f. they sell a plate for it. I have a different ECU so its all programed though it.

    You are right itīs not advanced.
    We are racing with it advanced 6* but you donīt see the big gains the 250 guys see. We only get a slightly better holeshot.
