For the moment the bike won't start
Cylinder replate, new piston, new connecting rod, new crank bearing, new plug, new air filter, new clutch basket, new clutch plates, and fresh fuel mix. Carb fully cleaned with new seals and choke. Frame paint removed for electrical contacts. It only run 1-2 seconds with the first kick and after nothing. I got sparks when kicking. The first time I tried the carb boil was full and gas sank by the overflow pipe. I checked the float level. It's not easy to mesure but it seemed little bit too height so I corrected it. But the result was the same except for gas overflow. I find that I don't have a lot of gas on the sparkplug, like the opposite of a flooded engine.
