80 mph Ultra 250x
What are the main/best/cheaper mods to reach 80 mph with a 2008 Ultra250x?
Anybody have reached this speed?

you can get hp to the engine very easy, its the first step,
for speed you need perfect combo between intake grate, ride plate impeller and magnum pump.
i call it "happy testing"

In this video you can see cyrille lemoine going 80 mph wot...
you can see in the start line more than 50 skis,including many ultras
with too much $$$ invested...
If they were going 78 mph they would be at least close.....
So these speeds are, for now... a dream

Lemoine ski is very fast but we are talking about factory racing engine with not a stock rxtx hul but very modded... Aski of a lot of$ ; not about an ultra simple modded.
