    Ultra 150 CV carb mod low on rpm's?

    Took my 02 Ultra 150 out today with the new cv modded carbs from Skiworx. It ran good but the rpm's were in the low 6k range? Before the cv mod I could get almost 7k. The plugs look like a nice golden brown.Do you have any ideas?

    I took my '99 out today for the first time without premix after a fresh rebuild . I'm 6000-6200 wide open so I'm also interested in what items to look into.

    Did you send the airbox/flamearrestor along with the carbs for the mod? It is modded along with the carbs.
    Try running it up to speed with the seat off. Maybe be starving for air.
    Did you reconnect the TPS Sensor? and calibrate it?

    I fixed it it was a stuck slide.

    How did you tell the slide was stuck. Could you fill it sticking by just pushing it up/down with your fingers or ...?
