    Question 4 tec counter balance shaft

    I have a few balance shafts all the same part numbers but i have 1 that is hollow you can see through it. What year engine were these hollow shafts used? I think they they breath crankcase ventilation through the shaft. Anybody have a answer i am thinking 2004-2005 engines thanks keith 6103926065

    My rxp has the hollow shaft and was built 6/06. Also had the better valves. If those are solid they must be one heavy SOB.

    I'm Curious?
    What is the weight difference between the two?

    Hollow shafts are on the newer skis from 06 and up.The older ones had plugs on each side.
    This done because of the change of crankcase ventilation!
