I cleaned the pipes (or is it called cap, I'm sorry but I'm not familiar with english terms) even better they are now shiny, I tightened the contacts of the power to the coils and i also cleaned them, they were toooo dirty and although it was raining hard last night and I was not able to ride for quite some time and the way that I wanted, the bike is in a good shape again and I could say it performs even better.
Thx for the help.
