Simson Enduro tuning

Hello guys, I`m from Bulgaria and I don`t know German , and Google translator isn`t good. I was hoping if there is someone that could help me with some enigne tuning on a Simson s51 enduro. I don`t mean kits or things , I am thinking about little improvements like lightening the flywheel , making the combustion chamber smaller to get higher compression . These are my ideas by now. I was wondering if you could give me any other tips about tuning my Enduro
P.S: If I posted it in the wrong section move it . I`m sorry

Re: Simson Enduro tuning

I am keeping my current Simson bike and getting another one to modify it`s engine. The tuning will be only performance , I don`t like visual tuning too. And I saw this tutorial http://www.scribd.com/doc/64106244/E…t-2-Stroke-Calc but I don`t understand so I`m helpless. What tools do you use to make the cylinder from 2 canal to 4 canal ? And are there any more pictures while somebody is working on it so I can see what exactly should I be doing ?

Needs a repaint and some other minor stuff but in general it`s an awesome bike

Zitat von STM

the instructions is long and you need some foreknowledge.

i think this is more simple [Blockierte Grafik: http://www.simson-portal.de/cache/86_0_0_images_stories_bauplan_s51_7ps.gif] this is with 4 canals

or this [Blockierte Grafik: http://www.simson-portal.de/cache/85_0_0_images_stories_bauplan_s51.gif] this is with 2 canals

Is the upper part of the picture the canals ? Because I really can`t understand much even tho I worked on my bike before , and I owned another 2 stroker which I disassembled but still can`t understand which is which on the pictures .
