You'll need metric sockets & wrenches. Standard gear pullers can be used with a little common sense... and maybe a touch of heat. Ring sticking from carbon buildup is the most common problem, causing cylinder wall scuffing and possible in flight seizure. Regular checking through the exhaust port at regular intervals (40-60 hrs) will let you know when or if to decarbon (remove heads & cylinder walls & clean pistons & rings) the engine. I would say just about all of the 503's out there have way more than 300hrs without a crank change and the most of the 582's. Once again, a little common sense, attention to detail, & regular maintenance will keep these baby's ticking for a long, long time. These were originally snowmobile engines adapted to ultralights. Many of those have over 2 thousand hours on them. To answer about a thousand of your questions I would recommend "Deep Inside Your Rotax 2 Cycle Engine" by HomebuiltHelp. www.homebuilthelp.com BUT, unless you have the ability, desire, & confidence to work on them yourself OR you have lots of money and live close to a Rotax Repair Center you might want to consider other alternatives, if you want to spend much time in the air.

I think the one from CPS is supposed to be better.
