    A prop alone doesn´t help.

    Think about another air intake 4´kanaflex,and another intake grate.

    Otherwise no gains are seen.

    No idea if the aftermarket parts for the is models are available yet.

    I will pop the top off mine next week to do the 4" air. It's tight in there. I will post pic's when I do it.

    Is there a different prop available or is the drive shaft splines different?

    I heard the splines ARE different, the mounting of the pump IS different. It bolts to the rideplate on the bottom

    ....

    whats the point of moding the IS with out changing the ecu chip? i thought the ecu in the IS skis limits the skis speed VIA gps. so nomatter what it will not let you gain anything over its current performance. other then acceleration perhaps

    I've heard the speed limit story and at first it was 65 now some say 70mph. Mine did 70 stock and I will soon find out if it goes faster after mods.
