Hello, Im finnish and I can speak and write only a little bit of german, so I'm going to tell it on english. I am probably going to buy this cylinder-crank-clutch kit. Is it good? How much horse power with this kind of setup I tell below. http://www.gearparts24.de/zylinder-kurbelwellenkit-top-performances:a5028.html 21mm dellorto racing, what if 24mm? turbokit carrera 80cc cross, because of cheap price from friend possibly ignition, if brother wants to of course i will buy other parts I need, like intake and possibly v-force 3. And then. What is the durability of this cylinder? How often I must change piston? Is this cylinder classed on highend or midrace? Is this cylinder good for daily use? I am driving like 4000-5000km in a year, so not that much... I could do well, if piston change is once in 3000km. How much fuel this would take in 100 kilometres? From 1-10, 10 highest, my throttle hand is probably 2-3. Very seldom driving on full throttle. If this cylinder kit isn't what I am excepting what would you guys support? Durability: about 2000-3000km. Horsepower: enough to beat 4-stroke 125cc, looking for 16-21hp cylinder with good durability. I prefer top performances Thank you guys! If you understand, i'm not sure how good german peoples english skills are but i hope better than french guys
