    Why spend $250 when you can mod the stock one for less than $10........ and get the same results.....................

    better results on the timing mod on the 250 than the 15f.

    get the ada racing one if u wanna try it.

    The ADA only goes to 5 degrees. I'm looking at going higher. I have heard it working for the LX.

    According the the exploded view of your ski, the timing rotor is not the same as the LX or the 250. Other people have tried the ADA rotor and the results weren't good. They needed a higher octane gas and the only gained on low and mid range. If somebody figures something better out, let me know cause my buddy needs some more speed for his 15F.

    It's all trial and error. That's the name of the game. I know the rotors are different, but changes in performance on the LX may equate to performance on the 15f. If it doesn't work, it's only a $20 hit.

    I had the ADA unit on my 15f. I had it on 5 degrees. I didn't gain any top end with it. Accel was hard to tell but I didn't feel anything there either. The 15f comes with a good amount of timing as is and is already pretty efficient.


    The Ultra's timing is low because Kawi is worried about people grenading the motor with low octane and then blaming them. To low of timing can cause air/fuel to be burned in the exhaust instead of the cylinder and that greatly reduces efficiency. It's no wonder why guys are getting better mileage with the timing mod on the Ultra. I'll be testing the timing on the Ultra today.
