    Had my shop order the parts for this upgrade. Having it done next week to my FH680V (23 to 25hp). Hope this helps on the rider with this thick growth and the E-Z Vac.

    I have a FH601v-DS22 and in the process of upgrading the carb shaft to 25hp. The carb is completely off and the old shaft is removed only to find that the new shaft Part # 16041-7025 is too thick to slide into place. The old shaft is .270" diameter and the new one is 0.275" in diameter.
    Are there raceways or sleeves that need removing?

    Well, something told me to double check part numbers and then to double check my engine plate. Its a AS22 series and needs a Part # 16041-7014. My bad.
    Guess I will need to send this one back to M&D or does anyone want one immediately.

    3400 rpm ? I ran mine for the first time today with the tach. Idle was ok at 550-575 but i have to idle it down from 600 by hand at the throttle shaft. What surprised me by this post is i'm only at 1800rpm at full throttle.

    First time I have heard of that problem.When I did mine I changed the whole carb because of another problem.You mite check your throttle cable install.

    New guy here... Just read this thread and immediately ordered all the parts to make my 19 hp FH601V a 25 hp. I just bought a gently used Country Clipper Jazee Pro and am excited to boost the power. I've got all the parts coming for the oil cooler addition and plan to Dremel the throttle shaft rather than replace it. Only thing that concerns me is the governor adjustment, but I'll read this thread again and study the shop manual. The Jazee already rocks, this should be icing on the cake. :cool:

    Part #59071-7009 Joint has been discontinued by Kawasaki. Anyone have a lead? Most websites will show the part number and let you order it, but a week later you call and find out its not in stock and not available. Need to find a dealer that has NOS.
