    My son is running MicroMax this year and with the introduction of the Rotax series in SoCal I’m thinking that I may have him run Rotax one more year instead of switching to the MiniRok. I need to have the engine done, but I know that Rotax motors are pretty good at lasting. How often (hrs) do I need to get the bottom and top end rebuild. I know the top needs it, but I’m not sure how often the bottom does. I’ve looked but haven’t found what I’m looking for in the forums. TIA

    Thor,

    Not very detailed but, see pg 35 of this:

    More downloads here:

    At least it seems to be a very lightly stressed engine.

    I question whether you could ever wear out a Micro Max motor.  I know we have run Juniors 60 hours and Mini Max motors could go that long and probably longer.  Considering a Micro Max rarely goes above 10k rpm for a motor that is designed in the hardest use (Senior and Masters classes) that can go 40-50 hours I guess a Micro Max motor could last 80-100 hours.

    Thanks for the info and the PDF from Rotax. Amazing that the Rotax motor isn’t more popular in the US, well at least in the west where I live. Hope the SoCal Rotax series takes off for next year.
