the crank is good for 2000km.
piston 500km, cyl 1000km
in the vrra, we do a little less then 500km/year. (that's doing the 4 weekend)
I read a lot of people do 600 to 750km with a piston. and they still do 2 piston per cylinder and/or 4 piston per crank.
the cost involved is more then a 4cyl. but it's not hard mecanic.
You don't need to split the cases between crank change.....(unles you crash and sand get in it...lol)
the overhaul once a year(splitting the cases) I said is to check everything just to be sure and clean everything well...it's not 100% mandatory.
