What all do you want to do to it?  A simple decarb is pretty easy.  Further in gets harder and requires more tools.  JImChuk

I see Bill Larson advertising all over barnstormers about doing rebuilds.  He seems to be pretty reasonable and gives you a warranty.  He is in Oregon as well.

I keep eye balling some of the Hirth engines as a possibility for an upgrade for me one of these days.

My recommendation would be to have an experienced mechanic to do anything other than minor engine work.                           These engines are very simple but require some specialist knowledge and expensive tools to be done right,the cost of failure isn't worth the risk! I have seen many failures due to "tinkering" and unfortunately the engine gets blamed,the 582 is an amazing and reliable engine .

I am fortunate that our local rotax mechanic has over the years allowed me to to work on mine under his supervision,there are a few tricks and pitfalls,if you can get the same service it will be very rewarding.

Aftermarket parts,myselfe and the local mechanic preferr them based on value for money.                                                               We recently installed a SPI?top end kit in my 582, it cost less than 1 bare genuine rotax piston(I had to purchase the rotax careless bearings)the quality was impressive and i have gained a noticeable increase in power.

I hope the rings on the SPI pistons are better than they were a few years ago.. Both Bob and I had rebuilt our engines using SPI pistons.  The pistons were fine but the rings turned to butter in under 5 hours on both our engines leaving us with the compression of a turbine engine... I am running WSM pistons in mine for the 580 seadoo and they are working out great.  I am pretty certain this is what rotax rick has been using as well. 

I have a DVD called "deep inside your rotax"  its a great DVD for someone wanting to rebuild their own engine.  The rebuild manual is also on line here and ifg you go through it step by step its hard to screw it up.  The biggest thing to remember is... drum roll please... DO NOT try to put the RV valve in when you have the engine upside down unless you really study the installation.  Yes I have done that once and it kicked my ass and took me a bit to figure out why the engine wouldnt even try to run :lol: 

As far as "specialty tools"  A dial indicator and a set of feeler gauges along with a TQ wrench is really all the specialty tools needed. You can use the exhaust manifold to line the jugs up before you torque them although the line up plates are cheap to buy.  You can also buy a leak test kit and it is very simple to check your seals at your yearly condition inspection.  I use a 30 dollar fly wheel puller to pop the mag off, its cheap and easy and work well.  There are a couple different types of loctite used, these are called out in the rebuild manual and it tells you which ones to use where.  If you have ever had an engine apart before there is nothing earth shattering about these engines.  A little reading, some due diligence and paying attention to what your doing and its easy!

If you can find a piston clip install tool, that makes it dead easy.  If not, a screwdriver with a notch filed in it works OK but be prepared to send a clip or two flying across the shop and learning a few new cuss words the first time you are trying to install them :lol:

another option that looks really nice is that Simon Victor engine we see around here every once and a while. I think that's what its called. It looks like a damn nice engine, As always 912 and Jabiru are nice replacement engines too,

You mean the 90 hp Simonini like Fred has on his bird?   There was one with 240 hours on an X-Air bird on ebay.  EDMO

The SPI kits must have got their act together as 25 hrs and all is good,the correct tooling is crazy expensive here.                         The Clip installer and the pin remover/ installer are a must have as I have a parts 582 that was rebuilt without the correct tools and experience,after 15 hours half a top end roller fell out and destroyed the engine .The aircraft landed safely but the owner will never fly behind a 2 stroke again as he now believes they are unsafe which is a unfortunate.

Justin, are you running a 670?  Or did you have him rebuild a 582 for you?  If a 670, what are you using for an exhaust system?
