Never used one in years of working on MZs. ( I have now got one somewhere that I got given when I bought a ES250/1 outfit form Germany... God knows where it is though)
Remove all the screws.( Are there 13 of them? (it's late and a while since I did it!) knock out the dowel at the front of the crankcase.Then I would play a Paint stripper hot air gun over the main bearing until I got bored and use my favourite tools, a old butter knife ground to a sharp edge and a hammer and tap round the crankcase until the cases parted enough to use a pair of tyre levers to totally remove the generator side case.
With practice I could split a Supa5 engine , replace all the bearings and seals and rebuild it over a weekend ( well it was that or not being able to get to work on Monday!). Follow the book, take it easy and they are a very simple engine to rebuild
ES250 Doppelport, ES250, ES250/1, ES250/2,ETS 250, ES150, ETS150, BK350, IWL Pitty, SR56 Wiesel, SR59 Berlin, Troll............ and thats just the German two strokes!
